Good Math, Bad Math : The Real Murphy's Law

Good Math, Bad Math : The Real Murphy's Law: "The real Murphy's law: If there's more than one way to do something, and one way will result in disaster, then someone will do it that way."

We can transform single thread to multithread: Intel

We can transform single thread to multithread: Intel: "“Our answer is CT: C stands for C++ based MPI and T stands for high throughput. So programmers can run C++ like scalar code, and our CT code will do everything that an experienced programmer will do like parallelisation and vectorisation.”

Intel has already got the technology working on quad and eight core platforms, and says its existing test applications can run on upcoming terascale platforms without modification of any code.

The closing words were amusing: “If you are a programmer, please do not worry about being fired because you cannot do terascale programming, because CT will blast you into the parallel era.”
Speculative parallel threading

The next presentation was also on helping programmers with multithreading. However, with this technology, rather than programmers having to do any recoding, it’s a new compiler that can take single thread apps and make them work in a multithreaded mode.

The way it works is it analyses applications to see whether a part of the application can be selected and made to run parallelly. If it executes successfully, the software knows it can, and it allows an application to be recompiled with the settings in place for that thread to run in parallel.

Intel explained, “It’s different from CT because CT is a new progra"

InternetNews Realtime IT News – SAP Open Sources Memory Analysis

InternetNews Realtime IT News – SAP Open Sources Memory Analysis: "was an original member of the Eclipse consortium, which began in 2001, and it was a founding member of the Eclipse Foundation in 2004, so it's not surprising it chose Eclipse to contribute to.
Memory Analyzer provides a graphics-based snapshot of object-retention patterns and provides developers with the information they need to optimize memory usage without interrupting the business applications in use or crashing the Java virtual machine hosting the application.
This belated gift to the open source community comes about two weeks after SAP announced that for the first time since its debut in 2003, developers can now buy an annual developer license for its NetWeaver platform directly from its Web site at a significantly discounted price.
Both of these strategic decisions are intended to grow SAP's Developer Network from roughly 900,000 developers to more than 1.5 million developers by the end of 2008.
Michael Bechauf, vice president of standards for SAP's Global Ecosystems and Partner Group, said SAP held off on sharing the code until it was confident the Eclipse environment was developed enough to support the needs of large enterprise customers running multiple, high-volume applications at the same time.
A Memory Analyzer plug-in has been available for download from SAP's Web site at no cost for more than a year. And customers with full NetWeaver licenses have been using it even longer."

Virtualization

This paper:
What Programmers Should Care About
The previous sections highlighted the changes a program experiences when being executed in a virtual machine. Here is a summary of the points that developers must be aware of.
Accessing devices, such as hard drives, NICs, and graphics cards, can be significantly more expensive in a virtual machine. Changes to alleviate the costs in some situations have been developed, but developers should try even harder to use caches and avoid unnecessary accesses.
TLB misses in virtual environments are also significantly more expensive. Increased efficiency of the TLB cache is needed so as not to lose performance. The operating system developers must use TLB tagging, and everybody must reduce the number of TLB entries in use at any one time by allocating memory as compactly as possible in the virtual address space. TLB tagging will only increase the cache pressure.
Developers must look into reducing the code size and ordering the code and data of their programs. This minimizes the footprint at any one time.
Page faults are also significantly more expensive. Reducing the code and data size helps here, too. It is also possible to prefault memory pages or at least let the kernel know about the usage patterns so that it might page in more than one page at once.
The use of processor features should be more tightly controlled. Ideally, each use implies a check for the availability of the CPU feature. This can come in many forms, not necessarily explicit tests. A program should be prepared to see the feature set change over the runtime of the process and provide the operating system with a means to signal the change. Alternatively, the operating system could provide emulation of the newer features on older processors.

Intel set to take leap in solid-state drives Nanotech: The Circuits Blog - CNET Blogs: "Currently, the fastest SSDs from companies like Samsung approach 100MB/second for reading data. 'What I can tell you is ours is much better than that,' Winslow said. Hard drives typically read data at about half this speed.
'We will be supplementing our product line with a SATA offering,' he said. Serial ATA, or SATA, is an interface used in high-performance hard disk drives. Intel's products will be based on the SATA II specification that offers speeds of 3 gigabits (Gb) per second. Samsung is now shipping 64GB SSDs to Dell using the same technology."

Bloglines | My Feeds (2175) (1)

Bloglines | My Feeds (2175) (1): "What strikes me from reading the Nexus specs and that of the associated NX-OS operating system is how this new switch reminds me of an old mainframe. Nearly all services are virtualized, with multiple copies of the OS starting and stopping as needed. Everything is redundant, isolated, and intended for nonstop service. It is hard to imagine when, if ever, you'd even need to reboot. And while the Nexus supports network connections up to 10 gigabits per second, the really fast networking takes place in parallel between cards over a passive backplane. The Nexus 7000 is a data center in a rack, only with dramatically reduced cooling and power requirements which suggest to me that Cisco has a growth strategy for this architecture that will, over time, make it look more and more like a big computer and less like a router. Throw on a virtualized AIX or Solaris and the Nexus will eventually reveal that its true competition is less likely to be Juniper than it is IBM, HP, and Sun."

VMware Spruces up Desktop Offering

VMware Spruces up Desktop Offering: "VDM2 lets companies manage multiple desktop images running on virtual and physical servers in their datacenters. It takes all the computing required for an organization's desktops, laptops and thin clients off the hard drive on the edge of the network to virtual servers where administrators can manage hardware upgrades, monitor application use and secure data access from one central location.

Having the ability to capture 40 or 60 desktop images on a single server sounds great, particularly when these desktops can easily be moved around on virtual machines hosting other application workloads, but so far only the earliest of adopters have embraced desktop virtualization.

'It's absolutely in its infancy stage,' Michael Rose, an analyst at IDC, said in an interview with InternetNews.com.

Rose said few people are deploying server-hosted virtual desktops. 'No one is going to roll out 100,000 virtual desktops tomorrow,' he said. 'It's still very early.'"

Linux Love - Part 7

Linux Love - Part 7: "To give you some statistics: the drive is rated for 600,000 load/unload cycles, and after 2.5 months of running Feisty I’m already at more than 56,000 load/unload cycles (and only 150 power cycles), according to the SMART data. At this rate the drive will be dead after 2.5 years, and I don’t even use this computer for more than a couple of hours each day. Are YOU affected? If you’re running Ubuntu, you should know that the only way to see the number of load cycles is by using SMART tools which aren’t even installed by default. To install them, simply run: $ sudo apt-get install smartmontools Now, to find your drive’s load cycle count, run this command in a terminal (replace /dev/sda to suit your computer configuration, /dev/hda for example if you have ata drive): $ sudo smartctl -a /dev/sda | grep Load_Cycle_Count You should see an output like this: 193 Load_Cycle_Count 0x0012 095 095 000 Old_age Always - 55380 In this example, 55380 is the load cycle count which SHOULD increase by 3-5 in an HOUR. But if it’s increasing by 3, 5 or more in a MINUTE, there’s definitely a problem. Think about it: HDD manufactures are claiming that a drive will support about 600.000 load cycles, meaning that your drive should be fine for a few years. But when the count is"

It comes preloaded with a modified version of the free Linux operating system and a set of basic applications, none of them from Microsoft (nasdaq: MSFT - news - people ). There's no power-gobbling microprocessor from Intel (nasdaq: INTC - news - people ) or AMD and no optical or hard drive, just 4 gigabytes of flash memory so you can store a few files locally. The bulk of your files are stashed on the Web, thanks to a deal Zonbu struck with Amazon's S3 online storage service. The catch, if you want to call it that, is that the $99 price requires you to pay a monthly fee for support and software updates. The fee is based on storage, ranging from $13 for 25 gigabytes to $20 for 100 gigabytes. Supposedly the lower-power chip can reduce your electricity bill enough to make up for the monthly fees to Zonbu. Remains to be seen."

FrankFi's view of the world : Does IT matter? Some thoughts on SaaS

FrankFi's view of the world : Does IT matter? Some thoughts on SaaS: "So first let's think what a pure SaaS solution means: The application as well as the data is stored 'in the cloud'. (I do here a simplification I know). Is this enough? Sorry, no. But there are lots of people thinking that it actually is enough and it is totally understandable. If you see IT as a simple tool not as a strategic asset then you can stop reading here. But IT can do more if you release its powers. How can this work? Well, let's extend our definition... There is this nice architecture model with 4 distinct steps to make a SaaS application. It is all about making the application scalable and lower the invest per customer instance in CPU and memory while preserving the agility in it. Applications have to be highly customizable. It starts with the logo in the top left and ends customer specific processes. So I would add: The application is highly customizable."

TidBITS Entertainment: Amazon MP3 Takes on the iTunes Store

TidBITS Entertainment: Amazon MP3 Takes on the iTunes Store: "Amazon.com has launched a public beta of Amazon MP3, a digital music store that provides DRM-free downloads of over 2 million songs from 180,000 artists and 20,000 labels. In comparison, Apple says the iTunes Store now contains over 6 million songs."

I've already started to pick and choose what I want, getting the best "deal", as I view it -- either better price, no DRM and probably better quality from Amazon or getting more selection from iTunes.

For instance, on Saturday, the wife and I were listened to Freddy Fender song. She said "play more of those -- do you have the "teardrop" song?" Unfortunately, I didn't have any more Fender songs, so I quickly opened up itunes store and the amazon mp3 store and started digging. I was able to grab a "live" album of all the top Fender songs from Amazon for $5.95. But they didn't have the "orginial" versions of some key songs, those I had to get DRM'ed from itunes.

EETimes.com - Analyst cuts AMD forecast amid MPU snags

Earlier this month, AMD released pricing for the nine models that make up its newly launched quad-core x86 microprocessor family, codenamed "Barcelona." The processor is based on 65-nm technology.
''We believe the company's late Barcelona introduction and disappointing early performance are an early indication of a bad marriage of process technology and design that will be hard to fix before a move to 45-nm is required,'' said analyst Doug Freedman of American Technology Research Inc., in a new report.
''AMD still has a lot of work to do to fix the architectural mismatch of Barcelona with the 65-nm process node and the poor performance of R600,'' he said, referring to ATI's latest graphics chip. That chip is also late to the market.

Virtualization Brings New Data Recovery Concerns, Benefits

Virtualization Brings New Data Recovery Concerns, Benefits: "The data is backed up but the systems are not. How do you effectively recover an entire server? The data is helpful but what about the tuning parameters for a SQL server, the patches and the database drivers? Everything that goes around that data is important. The more you have to do, the longer it takes to recover your environment,' said Stetic. PlateSpin's PowerRecon software basically does an inventory of a datacenter's physical and virtual machines, telling users how much processing capacity is required to keep them humming along and helps locate excess capacity so IT managers know where and how to begin the process of consolidating their datacenters. Its PowerConvert software streams workloads between physical servers, virtual machines, blade servers and back-up archives. 'The biggest challenge of whole system recovery is resolved because you no longer need the same type of hardware to restore your data,' Stetic said. '"

At the age of 40, with the cutoff date for sabbatical being 8 months away, and never having climbed a mountain, Neal decided he'd like to climb Everest. People said he was nuts, that you need to train for years, etc. He decided to do it anyway. He started training by running 8 miles a day every day but Sunday. Sundays he'd climb a local 1200 foot mountain - twice - wearing a 50lb backpack. Then, within the next six months, he climbed Mt Rainier in Washington (14k ft), Haba mountain in China (18k ft), and mt Aconcagua in Argentina (23k ft). Then he summitted Everest this past May. Some people feel that Everest has gotten easier because you hear about all the 'for hire' expeditions that are doing it.

Now, we are getting two new errors. First, at random times, the computer will stop being able to connect to the internet. It will have a good wireless signal, and see other computers on the network fine, and the other computers on the network will see the internet, but Vista does not. Just rebooted the computer into the XP partition, and XP sees the Internet fine -- its just Vista that is broken.

Gamasutra - The Top 10 Myths of Video Game Optimization

Gamasutra - The Top 10 Myths of Video Game Optimization: "When comparing the growth rate of instructions retired in the past five years, the GPU is the winner. The CPU, by means of increased instruction level parallelism and multi-core is in second place. The slowest growth (of resources commonly utilized in game runtime) is the memory system."

Virtual PC Guy's WebLog : Detecting Microsoft virtual machines

Virtual PC Guy's WebLog : Detecting Microsoft virtual machines: "The easiest way to detect that you are inside of a virtual machine is by using 'hardware fingerprinting' - where you look for hardware that is always present inside of a given virtual machine. In the case of Microsoft virtual machines - a clear indicator is if the motherboard is made by Microsoft:"

Quote on bottleneck on Virtual Machines:

Random Musings of Jeremy Jameson : Performance of Virtual Machines: "I have seen many VM environments where organizations use a high-end server with 4 or 8 state-of-the-art processors and 'gobs' of memory and subsequently assume that they can run 4 or more VMs on this one server without a problem. However, as noted earlier, CPU and memory represent only half of the resources that can ultimately become a bottleneck. In my experience, most VMs bottleneck first on disk I/O."

Good oveview of AMD's poor benchmark showing on Barcelona..

This report summaries the current benchmark findings rather well.
And then concludes:


Barcelona needed to be a slam dunk for AMD. It has turned out to be much less. AMD now needs to focus solely on solving their manufacturing issues and releasing faster clocked Barcelonas. AMD's customers need to be knowledgeable of the fact that several of Intel's upcoming 45nm products will be here in a few months. These will likely deliver better performance on less power.

If AMD continues as they have this year. If they continue to lose large amounts of money each quarter. And if they are not able to achieve high clock speeds with their 65nm SOI technology at a pace consistent with Intel's anticipated ramping at 45nm, then this launch will be the turning point. It will prove out to be the beginning of the end for AMD.

Until we saw Barcelona numbers there was always hope. AMD knew this and kept their cards very close to their chest, not even releasing products for review until late last week. Unless AMD can turn it around and significantly ramp up the clock speed to compete with and win against Intel's 45 nm competition, then AMD may be headed into a life-threatening storm.

Microsoft Virtual Hard Disk FAQ

Microsoft Virtual Hard Disk FAQ: "Virtual machine technology serves a variety of purposes. It enables hardware consolidation, because multiple operating systems can run on one computer. Key applications for virtual machine technology include cross-platform integration as well as the following: • Server consolidation. If several servers run applications that consume only a fraction of the available resources, virtual machine technology can be used to enable them to run side by side on a single server, even if they require different versions of the operating system or middleware. • Consolidation for development and testing environments. Each virtual machine acts as a separate environment, which reduces risk and enables developers to quickly recreate different operating system configurations or compare versions of applications designed for different operating systems. In addition, a developer can test early development versions of an application in a virtual machine without fear of destabilizing the system for other users. • Legacy application re-hosting. Legacy operating systems and applications can run on new hardware along with more recent operating systems and applications. • Software demonstrations. With virtual machine technology, users can quickly recreate a clean operating system environment or system configuration. • Simplify disaster and recovery. Virtual machine "

AMD Pins Hopes on Barcelona Quad-Core Chip

Because Intel's quad-core chips have been on the market for a year now, Hestor also acknowledges that AMD must deal with a peculiar PR situation: Trying to explain to the public why two cores is actually better than four.

Apple vs. Intel

see: http://www.apple.com/hotnews/openiphoneletter/

versus:

To all Itanium customers:

I have received emails from a few of our handful of Itanium customers, and they are upset about Intel dropping the price of Itanium by $5000 two years after it went on sale. After reading every one of these emails, I have some observations and conclusions.

First, I am sure that we are making the correct decision to lower the price of the 12Mb Itanium from $5999 to $19.99, and that now is the right time to do it. Itanium is a breakthrough product, and we have the chance to 'go for it' this holiday season. Itanium is so far ahead of the competition, and now it will be affordable by even more customers. It benefits both Intel and every Itanium user to get as many new customers as possible in the Itanium 'tent'. We strongly believe the $19.99 price will help us do just that this holiday season.

Second, being in technology for 30+ years I can attest to the fact that the technology road is bumpy. There is always change and improvement, and there is always someone who bought a product before a particular cutoff date and misses the new price or the new operating system or the new whatever. This is life in the technology lane. If you always wait for the next price cut or to buy the new improved model, you'll never buy any technology product because there is always something better and less expensive on the horizon. The good news is that if you buy products from companies that support them well, like Intel tries to do, you will receive years of useful and satisfying service from them even as newer models are introduced.

Third, even though we are making the right decision to lower the price of Itanium, and even though the technology road is bumpy, we need to do a better job taking care of our early Itanium customers as we aggressively go after new ones with a lower price. Our early customers trusted us, and we must live up to that trust with our actions in moments like these.

Therefore, we have decided to offer every Itanium customer who purchased an Itanium from either Intel or its OEMs, and who is not receiving a rebate or any other consideration, a $1000 store credit towards the purchase of any product at an Intel Online Store. Details are still being worked out and will be posted on Intel's website next week. Stay tuned.

We want to do the right thing for our valued Itanium customers. We apologize for disappointing some of you, and we are doing our best to live up to your high expectations of Intel.

Linux: The Really Fair Scheduler | KernelTrap

Linux: The Really Fair Scheduler | KernelTrap: "o here all the mathematical details necessary to understand what the scheduler does, so anyone can judge for himself how solid this design is. First some basics: (1) time = sum_{t}^{T}(time_{t}) (2) weight_sum = sum_{t}^{T}(weight_{t}) Time per task is calculated with: (3) time_{t} = time * weight_{t} / weight_sum This can be also written as: (4) time_{t} / weight_{t} = time / weight_sum This way we have the normalized time: (5) time_norm = time / weight_sum (6) time_norm_{t} = time_{t} / weight_{t} If every task got its share they are all same. Using time_norm one can calculate the time tasks should get based on their weight: (7) sum_{t}^{T}(time_{t}) = sum_{t}^{T}(round(time / weight_sum) * weight_{t}) This is bascially what CFS currently does and it demonstrates the basic problem it faces. It rounds the normalized time and the rounding error is also distributed to the time a task gets, so there is a difference between the time which is distributed to the tasks and the time consumed by them. On the upside the error is distributed equally to all tasks relatively to their weight (so it isn't immediately visible via top). On the downside the error itself is weighted too and so a small error can be become quite large and the higher the weight the more it contributes to the"

AMD announces 128-bit (GPU-oriented?) SSE5 extensions to x86

AMD announces 128-bit (GPU-oriented?) SSE5 extensions to x86: "EE5 also features new instructions for fused multiply-accumulate, integer multiply-accumulate, compare and test, permutation and conditional move, and precision control, rounding, and conversion. Some of these new instructions work with a new 16-bit floating-point format that SSE5 introduces. This 'half-precision' floating-point format is popular in GPUs, so this format and related instructions are likely intended for AMD's forthcoming 'Fusion' product. All told, SSE5 adds over 100 new instructions (base instructions plus variants) to the x86 ISA. No doubt AMD hopes to repeat history here—x86-64 history, not 3DNow! history—by getting Intel to eventually adopt the extensions. However, my (still fairly preliminary) reading of Intel's QuickAssist technology suggests that Intel will take a different approach to integrating many-core, GPU-style acceleration with the x86 ISA. More on this at a later time, though."

Metaphor of the Branch Predict

"branch predict".

I was struck by that phrase in a meeting a few days ago. It was used by a software engineer describing what he thought the direction of a project management team would be regarding a new product. Rewording his statement: "My branch predict is that they will kill this program".

Of course, these type of metaphors are common. Body-based metaphors are the very common ("the leg of the table"). These are followed closely by metaphors using mechanical analogies arising from common occupations. These are generally used to describe one's internal thought processes and/or personal situation. I have a "sea of troubles", I'm "sailing against the wind", I've "got my nose to the grindstone", that really "fuels my fire" (its fun to think of these -- go ahead try it!).

And so you might expect our age of advanced computers to generate a number of such metaphors. It was interesting to hear this fairly hardware-bound metaphor move into the group think of the software folks..

Many enterprise codes, such as databases or ERP systems, experience lots of branches -- They are "branchy". The standard metric used in analysis is the average number of "instruction between branches". This is a measure on the dynamic instruction stream (tracking the instruction pointer) rather than based just on static analysis. For instance, running SAP SD's benchmark, R/3 executes on the average about 6 instructions before it hits a branch!

Because of the parallel nature of the way our microprocessors' internal architecture works, if we waited to branch our front end instruction decoder till all the conditional values that decide a branch were ready, we could not continue to fill the pipeline and the machine would stall. So we must predict with high accuracy which branch target is taken and start to work down that path. If we do this with high enough accuracy, then we can afford the occasional miss-predict, when we must re-steer the machine and throw away some temporary results.

To do this prediction, the hardware uses a number of heuristics. These are the "branch predict" of the hardware.

Some heuristics are clear. For instance, on x86, loops are written ending in a direct branch backward to the start of the loop. Since most loops actually loop in applications (isn't that nice), then on encountering a backward jump the first time, our best assumption is the take the branch. This is static branch prediction (Intel® 64 and IA-32 Architectures Optimization Reference Manual http://www.intel.com/design/processor/manuals/248966.pdf)

Other heuristics are more complicated to implement but, as you might imagine, attempt to remember the history of the branch. Nothing predicts the future as well as the past, or as Lord Byron (Letters/1821) said: "The best of prophets of the future is the past."

For the most part, the branch predictor in current hardware does a great job. For some floating point/numeric codes (SpecFP) the predictor can get 98%+ accuracy. SAP's R/3, which processes enterprise data from many users, the miss-predict rate is about 6%. (However, even at this rate, we lose 7-10% performance from what an oracle-type -- e.g. "perfect" -- predictor could delivery).

Using "branch predict" in the context that started this article has a certain natural simple charm. After all, its just a slightly geeky way of linking us to our hardware while saying the single word "predict". Which was what my colleague was doing here - simply predicting the future based on his best knowledge. He wanted to let the listener know he wasn't guessing about the future status of the program.

So, in these days, the Dilbert-ian static predict for a project is: "This project will be killed". Augmented with other dynamic knowledge (schedule slips, perceived value to the customer, etc.) my colleague was able to succulently state his informed opinion on the direction of the project he was describing to us.

The Dread of Threads: " 'We get questions along the lines of, 'What could you possibly run that needs 128 cores on a laptop?,'' Patterson told HPCwire. 'This reminds me of the story of the patent examiner in 1870 who decided that everything of importance had been invented, so he quit his job to look for something permanent. Or that 640KB ought to be enough memory for PCs. We think the most exciting software has yet to be written, and it's going to be highly parallel.' "

Percent of you ancestor woman: 2to1 over male

See: http://tierneylab.blogs.nytimes.com/2007/08/20/is-there-anything-good-about-men-and-other-tricky-questions/index.html

why was it so rare for a hundred women to get together and build a ship and sail off to explore unknown regions, whereas men have fairly regularly done such things? But taking chances like that would be stupid, from the perspective of a biological organism seeking to reproduce. They might drown or be killed by savages or catch a disease. For women, the optimal thing to do is go along with the crowd, be nice, play it safe. The odds are good that men will come along and offer sex and you’ll be able to have babies. All that matters is choosing the best offer. We’re descended from women who played it safe.
For men, the outlook was radically different. If you go along with the crowd and play it safe, the odds are you won’t have children. Most men who ever lived did not have descendants who are alive today. Their lines were dead ends. Hence it was necessary to take chances, try new things, be creative, explore other possibilities.

IBM Unveils Information Server Blade to Help Enterprises Manage Information Overload

IBM Unveils Information Server Blade to Help Enterprises Manage Information Overload
...
The system runs on Red Hat Linux and is built on IBM BladeCenter HS21 servers with Dual-Core Intel Xeon processors. Based on low-voltage industry standard processors, the energy-efficient system also uses less power and requires less cooling than larger systems.
To ease management and enhance grid and virtualization capabilities, the Information Server Blade uses the IBM Systems Director portfolio to provide users with a centralized dashboard to discover and manage all workloads and physical and virtual machines within the pooled environment. It also provides seamless, integrated grid management with Tivoli Workload Scheduler LoadLeveler so workloads can be easily managed across blades. Tivoli Workload Scheduler LoadLeveler provides high workload throughput and efficient utilization of resources within grid clusters. New blades can be simply snapped into a grid to add more processing power as needed, and Tivoli Workload Scheduler LoadLeveler can be used to coordinate workload dispatching across multiple grids.
"As customers seek to minimize datacenter complexity and power consumption without sacrificing capacity or performance, they are turning more and more to integrated blade server solutions built on Intel Xeon processors to balance these needs," said Elliot Garbus, general manager of developer relations for the Intel Software and Solutions Group. "Together, IBM and Intel have enabled a power-friendly, highly-scalable, turn-key solution to help customers more quickly and easily modernize their information management infrastructure."

Pipelines, Latencies and Unrolling

Apple documentation!

There is quite a bit of variability between implementations of x86 based processors. Small parts of the design get regular tweaking even in minor updates to the processor. It is difficult to make sweeping generalization about the exact operation of various stages of the x86 pipelines: fetch, decode, dispatch, issue, execution and completion. Please see processor specific Intel documentation for a more complete description of the particular performance characteristics of each processor that you are targeting.

Generally speaking, the smaller register file on the x86 architecture compared to PowerPC is backed by a much larger reorder buffer, to reorder the execution of instructions to keep pipelines full. From the perspective of a developer experienced with AltiVec, it may initially appear difficult to keep pipelines full with eight registers. While this would be true of a strictly in-order architecture, the large reorder window allows the processor to pull future instructions forward to fill gaps in the pipelines to help make sure that the processor stays full. The processor may pull instructions forward from the next loop iteration. Indeed, in some cores it may not be uncommon to see several loop iterations unrolled in hardware in the reorder buffers. This process occurs transparently to the developer and may perform differently on different cores.

FROM an evolutionary perspective, monogamy looks good for females and bad for males. For mothers, it means devotion as dad is going to be around to help look after the kids. For fathers it is more of a prison sentence, because it restricts a male's ability to inseminate lots of females at relatively low cost. In most circumstances, unless the young are likely to die without paternal support, a male has little incentive to stay with an individual female when he has so many other females to breed with.

That, at least, was the conventional wisdom until fairly recently. But modern genetic techniques have shown that in many species females in apparently monogamous relationships often produce families that have more than one father. To explain this, biologists have theorised that these females are mating with males who are genetically superior to their regular mates, thus getting the benefit of parental assistance from a cuckold and good genes from a Lothario.

I, Cringely . The Pulpit . Mercury Rising | PBS: "Where's Googlization for the rest of us? It's called Appistry.
Appistry application fabrics take an application and spread it across tens, even hundreds of commodity processors. If you need more computing power, just add new nodes and the application will spread to them automatically, speeding up linearly as it does. If one or more nodes fail for any reason, they are simply ignored and the job continues minus those machines.
This is hot stuff and, talking with the St. Louis, Missouri-based company you'd think finding customers would be a breeze, but it wasn't at first. 'We've always been about commoditization and virtualizing lots of machines to one, but it is hard to get people to save 80 percent on something that wasn't broken,' said Appistry founder Bob Lozano, 'Potential customers kept saying, 'Help me fix this problem I can't solve,' instead. Where customers were willing to try us was on these large computational or large data-intensive apps -- tasks for which there was no minimally acceptable solution.'"

Build high-performance apps for multicore processors

Build high-performance apps for multicore processors The RapidMind Development Platform provides a simple single-source mechanism to develop portable high-performance applications for multicore processors. In particular, you can use it to develop applications that fully exploit the power of the Cell Broadband Engine™ (Cell/B.E.) processor's unique architecture by writing only one, single-threaded C++ program using an existing C++ compiler. In this article, author Michael McCool takes you on a guided tour of the RapidMind Development Platform.
