Interesting bit about nVidia Tesla V100 GPUs:
Assuming all those nodes are fully equipped, the GPUs alone will provide 215 peak petaflops at double precision. Also, since each V100 also delivers 125 teraflops of mixed precision, Tensor Core operations, the system’s peak rating for deep learning performance is something on the order of 3.3 exaflops.
Those exaflops are not just theoretical either. According to ORNL director Thomas Zacharia, even before the machine was fully built, researchers had run a comparative genomics code at 1.88 exaflops using the Tensor Core capability of the GPUs. The application was rummaging through genomes looking for patterns indicative of certain conditions. “This is the first time anyone has broken the exascale barrier,” noted Zacharia.

- yread 8y agoI wonder what the application was. There is not that much deep learning in genomics.
- alfalfasprout 8y agoThe tensor cores are simply matrix multiplication + accumulation. They don't need to be used purely for deep learning.
- dekhn 8y agoThe code is Comet https://www.sanger.ac.uk/science/tools/comet https://www.sanger.ac.uk/science/tools/comet and based on the PR I think they ran it in embarassingly (or lightly) parallel mode (IE, very little if any communication between nodes except for periodic reduces.
