Linux gets heart transplant with 2.6.0 | CNET News.com: "However, commercial use of the 2.6.0 kernel is still months off for most customers.
Red Hat, the top seller of the Linux OS, plans to incorporate 2.6.0 in its Red Hat Enterprise Linux 4 product, due in 2005, said Brian Stevens, vice president of operating system development for Red Hat. SuSE Linux, the No. 2 seller, has a more aggressive schedule but doesn't expect 2.6.0 until it releases SuSE Linux Enterprise Server 9 in the summer of 2004,"

3.1. Better Performance with Bigger Integers
- Long strings of bits and bytes [i.e., using 64-bit integers for data movement, zeroing, or logical operations on bit strings.]
(This turned out to happen via long long in C, which let people write code easily portable between 32- and 64-bit CPUs.)
- Graphics
- Integer arithmetic
"Most chips make addition and subtraction of multiprecision integers
(i.e., 64-bit, 96-bit, 128-bit, etc.) reasonably fast, but multiplication
and division are often quite slow. Cryptography is a heavy user of
multiple-precision multiplies and divides. Financial calculations could
use integer arithmetic; 32-bit integers are far too small, but 64-bit
integers are easily big enough to represent objects like the US national
debt or Microsoft's annual revenue to the penny." [still true!]
Note that for all of these, hardware support of 64-bits is a SPEED
difference, not a major structural difference, with use of long long
between 32- and 64-bit CPUs similar to use of long between PDP-11 and
VAX -the same code is used, but the smaller system needs to do more
operations.
3.2 Big Time-Addressing
"Perhaps more important than using 64-bit integers for performance is
the extension of memory addressing above 32-bits, enabling applications
that are otherwise difficult to program."

List of largest production data bases...
World's Biggest Production Databases Now Include Windows
by Scott Bekker
11/13/03 � Windows servers and SQL Server 2000 now power some of the world's biggest production databases, according to an annual survey from data management analysts at Winter Corp.
Waltham, Mass.-based Winter Corp. recently released results of its Winter TopTen Program, which is done annually based on customer surveys and a script run on the databases to verify the facts submitted in the survey.
For the first time, Microsoft products made their way onto some of Winter's "All Environments" TopTen lists, which include Unix and mainframe systems. A massive SQL Server 2000 production database run by Verizon Communications placed sixth for overall OLTP database size and third for largest number of rows in an OLTP database. The Verizon database is 5.3 terabytes and has more than 33 billion rows of data.
-- advertisement --
"We think it's a great win because a lot of times customers or partners don't think about SQL Server being this enterprise, mission-critical database," says Tom Rizzo, director of product marketing for SQL Server. "It's great that it's a third-party validation. We've always been saying, 'Hey, SQL Server can scale.' A lot of people looked at that and said, 'Hey, that's Microsoft saying that.'"
Meanwhile, an Oracle database running on a Windows server at HP also made the OLTP TopTen, sliding in at No. 8 at 3.2 terabytes in size.
According to Winter Corp., the largest OLTP production database is an IBM DB2 cluster system run by Land Registry. That mainframe-based system is 18.3 terabytes.
Two other SQL Server-based databases made the TopTen list for most rows in an OLTP database across all environments. A 17-billion-row database at Commander Communication ranked fourth, and another database at Verizon with nine billion rows ranked ninth.
Microsoft products were not yet competitive in Winter's other database category -- decision support systems. The TopTen consisted entirely of Unix-based systems ranging from a 29.2-terabyte Oracle database to a 9.1-terabyte NCR Teradata database. The largest Windows-based DSS database found in the survey was an 8.9-terabyte Sybase IQ system at ComScore Networks Inc. Sybase IQ systems at ComScore accounted for the top three Windows-based DSS systems. The fourth- and fifth-largest Windows-based DSS systems were Oracle databases at HP.
The largest Microsoft SQL Server-based DSS system was sixth on the list of the TopTen Windows-based DSS systems -- a 1.6-terabyte system at Arclight Systems, LLC.
To be considered in its annual survey Winter Corp. requires Windows-based databases to be at least 500 GB in size. Some 25 SQL Server implementations were entered in the 2003 run with databases that big or larger. Of those, 15 of the databases were 1 terabyte or larger and four were 2 terabytes or larger

The Register: "HP also announced that is has reached a 'Memorandum of Understanding' with SAP. The two companies have agreed to create tighter links between their various software management packages and to go after helping larger enterprises together. Touching. "
"The adaptive enterprise is an umbrella," said Peter Blackmore, executive vice president at HP, during a press conference held today in Germany.
The most important message on the day, however, came from Nora Denzel, a senior vice president and head of the adaptive enterprise at HP. Denzel is a rising star at HP and eloquent - to say the least.
"The more standardized you are the less costly it is to manage IT," she said, during the press conference.
For all of HP's slogan slinging, this really is what the company is getting at and doing a nice job of providing.
"IBM and Sun are still in separate domains," said RedMonk's Governor. "I think from their perspectives, they realize they have to change."
HP has all the right pieces in place thus far. It has a single chip vendor strategy with Xeon and Itanium, the HP OpenView package as a leading management platform and technology such as Utility Data Center humming away in the labs for future use.

Honolulu Star-Bulletin Hawaii News: "Another seal, RM34, born on the Big Island, has recently been relocated twice. Swimmers in Kealakekua Bay said they were 'nipped and groped' by the seal Oct. 17, prompting wildlife officials to move it Oct. 20 to South Point, its birth area. By last weekend the seal was back at Kealakekua Bay.
On Tuesday, RM34 was taken by boat to Kahoolawe in hopes that the island's small population of seals and lack of humans might prove a suitable new home, said Jeff Walters, a biologist with the state Division of Aquatic Resources."

Seal swims back to Big Island bay
By Karen Blakeman
Advertiser Staff Writer
The frisky monk seal of Kealakekua Bay on the Big Island was back at his old stomping grounds this weekend after he swam back from the waters off the southern tip of the island last week.
The 2 1/2-year-old Hawaiian monk seal called RM34 was sent to his birthplace off South Point after his antics � which included nipping and groping � became a danger to himself and swimmers.
But he traveled about 50 miles back to Kealakekua Bay, where he was spotted late Saturday, said Margaret Akamine, a wildlife manager with the National Oceanic and Atmospheric Administration who overseas monk seals.
Conservation officials are asking Big Island residents and visitors to stay clear of the 300-pound, exuberant and endangered animal until they can find a new home for him.
'This is a very endangered animal,' Akamine said. 'Interacting with him is bad for people and bad for the animal.'
Bad for the animal, she said, because if RM34 is to survive in the wild, he needs to learn that he is a seal in search of other seals, not humans. Bad for people, she said, because RM34's seal games, which witnesses characterized as 'nipping and groping,' can be extremely dangerous when played with much smaller animals like people.
RM34, Akamine said, will grow to weigh more than 600 pounds. His groping behavior, she said, 'is just what it sounds like.'
'He's a young boy,' she said. 'He's just playing out normal field behavior. Unfortunately, he should be playing it out with other seals.'

Ace's Hardware: "RDRAM could make a surprising comeback, thanks to SIS. SIS and Rambus launched today the SISR659, a chipset that is capable of using 4 (16 bit) 1200 MHz RDRAM channels. When you do the math you'll see that those four RDRAM channels can deliver no less than 9.6 GB/s (4 x 2 bytes x 1200) to the chipset. Of course, this awesome amount of bandwidth is going to be bottlenecked by the 800 MHz FSB of the Pentium 4.
To get better performance out of the otherwise wasted bandwidth, a Dynamic Look-ahead Cache and Adaptive Page Management can be found within the R659 chipset. The Dynamic Look-ahead Cache Intelligently prefetches data into an on-chip chipset cache, and lowers the latency of the memory subsystem. Normally, a pagehit on a well-designed DDR 400 controller like the i875p results in a 5 cycle latency: 2 cycles through the controller, 2 cycles for the CAS latency (assuming CAS = 2) and 1 cycle back through the controller. The look ahead cache reduces this to two cycles. If a page hit does not occur, PC1200 RDRAM should have a latency that is very similar to DDR400. Rambus and SIS claim that the latency of the RDRAM channels vary between 10 (cache) and 35 ns, while DDR400 memory latency should vary between 25 and 35 ns. "

Ace's Hardware: "Thanks to Arcadian for posting about HP's recent TPC-C submission for the 64-way Itanium-based Superdome. With 64 1.5 GHz Madison Itanium processors, each sporting a 6 MB L3 cache, and 1 TB of main memory, the Superdome has achieved 1,008,144 tpmC at a cost of US$8.33/tpmC. This is the first machine to break one million transactions per minute. The score is roughly 20% higher than HP's previous result of 824,164 tpmC. The primary difference between that result and the new one is a doubling of main memory from 512 GB to 1 TB"
ENT News | News: Itanium System Breaks 1 Million Transactions on TPC-C: "The result also widens the performance gap between scale-up Unix/Oracle and scale-up Windows/SQL on HP's own 64-processor Integrity Superdome system. HP is now getting 28 percent better performance with its own Unix operating system and Oracle's new 10G database on the system than it got with Windows Server 2003, Datacenter Edition, and SQL Server 2000, Enterprise Edition. Both the Unix and Windows software stacks used in the tests are 64-bit."
ENT News | News: High-end Microsoft Stack Cheaper Than TPC Comparison Suggests: "When running basically on the same huge HP Superdome server with 64 Itanium 2 processors, the HP-UX/Oracle combo performed 17 percent better than Windows/SQL.

Monk seal moved again
By MAILE CANNON/ West Hawaii Today
A monk seal, already once removed from Kealakekua Bay, is in captivity again and en route to a new undisclosed location after reappearing at the snorkeling site over the weekend.
Authorities hope the latest attempt to relocate the seal will be effective in reintegrating it into its natural habitat and are calling on the public to help.
"These are wild animals and people need to leave them alone," said Margaret Akamine, of the National Oceanic Atmospheric Administration.
The manager of the protected resources division of the NOAA Fisheries Pacific Islands regional office said the endangered seal has been interacting with people and such behavior is detrimental to the animal and people.
The seal weighs 300 pounds and is about 3 years old, she added.
The seal was captured last week in Kealakekua Bay and returned to its birth place near South Point. Authorities began looking for the seal when radio signals from its transmitter tag stopped, Akamine said.
Relative to human development, the seal is a teenager, Akamine said. It's necessary for the seal to interact with seals its own age to properly develop and interaction with people stints that process, she said.
The options of places to relocate the seal are limited, Akamine said, and if the seal continues to interact with people it may have be kept in captivity. In an attempt to thwart the seal's efforts to get friendly with people, she said, its new locale is not being disclosed.
The estimated 1,200 to 1,400 Hawaiian monk seal population is protected by the federal Endangered Species Act and the Marine Mammal Protection Act, Akamine said. It is a crime to harass or interact with them, she added.
