Later tuning efforts had improved ASCI White
's MTBF to 55 hours, Fiala said.
ASCI Purple will cost $1.90 per gigaflops, and while this is a big improvement over the ASCI White
parallel supercomputer IBM built for DOE a few years back (which is rated at 12.3 teraflops and which cost a little over $8 per gigaflops), Blue Gene/L only cost 28 cents per gigaflops.
It became operational in March 2002 as the world's fastest supercomputer, so quick that its raw processing power equaled that of the 20 speediest US computers combined, far outpacing the previous title holder, the IBM-built ASCI white
at Lawrence Livermore National Laboratory, which is used for nuclear weapons simulations.
The largest of these is the IBM-supplied 100 Tflops ASCI Purple (following the ASCI White
and BluePacific systems already installed), which will be installed at Livermore in late 2004.
--The second fastest computer is ASCI White
built by IBM, with a score of 4,967.
(IBM and Lawrence Livermore co-developed the world's current record-breaking supercomputer, the "ASCI White
" machine now in operation at the lab.) Compaq is racing IBM to see if it can better its record in the life sciences and is collaborating with genetic database company Celera Genomics and the DOE's Sandia National Labs.
With the unveiling last week of the computer dubbed ASCI White
, they have a machine that can perform the task much more quickly.
General John Gordon, the Department of Energy's under secretary for nuclear security, said the supercomputer - known as Accelerated Strategic Computing Initiative White, or ASCI White
- was the key to the country assuring nuclear deterrence, though it has a vast number of other uses.
The supercomputer - known as Accelerated Strategic Computing Initiative White, or ASCI White
, has a mind-boggling amount of other uses, say researchers.
The IBM machine at NERSC is the second most powerful supercomputer in the world, after IBM's classified ASCI White
SETI@home contends its network of computers is rated at 15 teraflops and has cost just $500,000, while IBM's ASCI White
supercomputer is rated at 12 teraflops and costs $110 million.
Some fill entire rooms, such as IBM's ASCI White
, which is capable of running at speeds of 12.3 teraflops, or 12.3 trillion floating point operations a second.
