AMD brings GPU technology to high-performance computing

AMD is introducing a high-performance chip package that uses a technology commonly
found in graphics processors, called parallelism, and applies it to general
purpose computing, the company announced Thursday.

Parallelism breaks computing work into individual tasks that are worked on
by a processor concurrently, or in parallel, instead of one after the other,
as many general purpose processors do today.

Parallelism has been in use for a long time in graphics chips from companies
like ATI and Nvidia. AMD, which bought ATI last year, said the technology also
works well for some types of mathematical computation, so it is using it to
speed up other applications.

Called the FireStream 9170, the chip package is aimed initially at high performance
computers (HPCs) like those used by scientists for climate research and oil
exploration, and by financial analysts for advanced number crunching. But it
could also be used more widely in the enterprise for tasks like video-editing
and security tasks, AMD said.

The 9170 will be priced at US$1,999, making it one of AMD's most expensive
products, but it offers up to 500 gigaflops of computing power, according to
AMD, or about 100 times the performance of one of its dual core Opterons. It
will be offered in new computers, but it could also be added to an existing
server or workstation with a PCI Express 2.0 x16 interface.

Software applications will need to be modified to take advantage of the FireStream's
architecture, and AMD will release a software developer kit along with the chip
package for application tuning.

AMD calls the computing style Stream
Computing, and it began life at ATI before it was bought by AMD. ATI announced
the first Stream product last year, but AMD didn't work hard to promote it.
It is throwing more weight behind the second iteration.

The FireStream is being manufactured on an advanced, 55 nanometer manufacturing
process and will use a "double precision" floating point technology
for scientific and engineering calculations. The processor board includes 2G
bytes of GDDR3 (Graphics Double Data Rate 3) RAM, a type of memory designed
by ATI, and consumes under 150 watts of power, AMD said.

AMD also announced it has joined Hewlett-Packard's HPC Accelerator Program,
suggesting the product will be offered in computers from HP.
