SGI to unveil new supercomputer

SGI is set to unveil a new supercomputer that packs far more computing power per square inch than competing machines, a breakthrough that will help the company compete in what the high-end computer maker calls a Renaissance in supercomputing.

The Origin 3900, which SGI will also show off at the Supercomputing 2002 trade show beginning 18 November in Baltimore, can hold up to 128 processors and fit into a single rack, said Addison Snell, product marketing manager for high performance computing at SGI. Current SGI Origin computers can hold only 32 processors in a rack.

"The Origin 3900 effectively quadruples the maximum compute density," he said. "It has the density of a blade but the architecture of a supercomputer."

Economising on space is important for a couple of reasons. Floor space in computing rooms is valuable, so reducing the size of computers saves money and expands the places where these systems can be installed. Versions of the Origin 3900, for example, could be fit onto an oil exploration ship or a plane.

The density of the Origin 3900 is largely accomplished through the low-energy characteristics of the company's MIPS processor, which consumes about 17 watts, about the same as a notebook chip.

Additionally, density increases performance by reducing the distance that signals have to travel between the processors, memory and other subsystems. The subsets of most large supercomputers are linked through cables. Because signals can't be accelerated, the best improvement lies in pushing the machines closer together.

The often-beleaguered company is hoping that these architectural changes will help it latch onto the recent increase in activity in the scientific computing market. The 11 September 2001 terrorist attacks and other events have breathed new life into the market, prompting companies such as IBM and SGI to enhance their products and service offerings.

"Clearly there are some areas of the scientific and technical computing market that are picking up," said Jean Bozman, a research vice president at market research firm IDC.

Life sciences has become one of the more active scientific computing markets. Despite the economic downturn, biotech companies are continuing to invest in computing capabilities, according to executives, because of the nature of their businesses and the potential opportunities. Also, "they have money," said one server executive.

In September, for instance, IBM formed an alliance with life sciences giant Applera to design systems and services for pharmaceutical research companies.

Military and defence contracting have increased recently, Snell said. The bulk of the budget increases, which are classified, comes from the creation of the Department of Homeland Security. Concern about US national defence is also a contributing factor. The computing power of NEC's Earth Simulator sent shock waves through the US government because it marked the first time that Japan had a substantial lead over the United States.

"To the US government, this was a Sputnik class event," Snell said.

Large companies are also examining larger systems for testing and simulation. Proctor and Gamble, for example, uses a SGI system to study the aerodynamics of Pringle's potato chips, Snell said. The chips are moving so fast down the conveyor belt that they take flight. Through aerodynamic modeling, the company can change the shape of the chips and speed up manufacturing. P&G also uses the system to study fluid dynamics in disposable diapers.

In the next few months, SGI will come out with its first Itanium 2 computers. These systems will hold 32 processors per rack and will run Linux.

The base configuration Origin 3900 comes with four processors and 512MB of memory. A beefed-up system with 128 processors and 64GB of memory sells for $2.9 million.
