Japan Unveils Next-Generation, Pascal-Based AI Supercomputer (nextplatform.com)

Posted by BeauHD on from the can't-stop-won't-stop dept.

The Tokyo Institute of Technology has announced plans to launch Japan's "fastest AI supercomputer" this summer. The supercomputer is called Tsubame 3.0 and will use Nvidia's latest Pascal-based Tesla P100 GPU accelerators to double its performance over its predecessor, the Tsubame 2.5. Slashdot reader kipperstem77 shares an excerpt from a report via The Next Platform: With all of those CPUs and GPUs, Tsubame 3.0 will have 12.15 petaflops of peak double precision performance, and is rated at 24.3 petaflops single precision and, importantly, is rated at 47.2 petaflops at the half precision that is important for neural networks employed in deep learning applications. When added to the existing Tsubame 2.5 machine and the experimental immersion-cooled Tsubame-KFC system, TiTech will have a total of 6,720 GPUs to bring to bear on workloads, adding up to a total of 64.3 aggregate petaflops at half precision. (This is interesting to us because that means Nvidia has worked with TiTech to get half precision working on Kepler GPUs, which did not formally support half precision.)

  2. Re:Pascal-based? by jbolden · · Score: 1, Redundant

    Well first off the super computers aren't about the Pascal language but the Pascal chip. I'd disagree that Pascal was all that proven out. It seemed very quickly to have had structural flaws which caused other languages to overtake it. Pascal was fairly low level yet it lacked good low level interfaces. Which is why it lost out to C. Pascal supports admit this and one of the main directions of Turbo Pascal / Delphi was to introduce into Pascal handling for lower level code (example partial compilation).

    If you think of Pascal as a higher level language where bad handling of low level code is acceptable it also wasn't competitive. Pascal is strongly typed but has a poor type system without abstractions. Making types difficult to work with under almost all conditions. It had poor handling of static vs. dynamic data including things like abstracting networks or file systems. There are lots of sacrifices in organization for ease in writing small compilers. A very good choice for early 1980s PC compilers that had to run off a floppy not a good choice since. The languages strictness on looping structures tended to result in duplicate code.

    Etc... Pascal was a partial success. But it died for good reasons.
