- I've been looking at the IEEE Computer Society magazine for Nov.'92. There
- is a photo of what looks like a water-cooled backplane with a bunch of
- motherboards plugged into it. There is also the following blurb:
-
- Fujitsu Ltd. has developed a supercomputer that delivers 355 billion
- floating-point operations per sec with 222 processors. The VPP500 vector
- parallel processor features a proprietary crossbar network that allows
- simultaneous communication to move between individual processing
- elements (PE's) at 800 Mbyte/sec with each PE operating at 1.6 Gflops.
-
- Distributed global memory space reaches a capacity of 55,000 Mbytes.
- This allows memory space physically incorporated in each PE to be used
- for storage as well. Programmers can thus us traditional programming
- methods to develop high speed parallel programs.
-
- The upgradable LSI system uas fabricated from gallium arsenide and
- runs UNIX SVR 4. System pricing begins at approximately $10 million. The
- company plans commercial shipment in Sept. 1993.
-
-
- This raises alot of questions. Are there any Fujitsuans on the net
- who might be able to post archetectural details?
-
- Is this a new instruction-set architecture, or is it compatable with
- something else?
-
- How does it do on benchmarks like big linpacks, or preferably, SPECrate?
- Is Fujitsu a member of SPEC?
-
- How many chips make up the CPU of one PE? What's the clock rate? How
- big is the cache? is main memory DRAM? How fast?
-
- Lots more questions come to mind, but lets see if anybody out there can
- answer any of these...
