Fewer servers – faster results
In practice, this translates into having to maintain fewer servers, but getting the job done quicker. The new supercomputers used at Oak Ridge National Laboratory and Lawrence Livermore National Laboratory have IBM Power9 processor nodes with NVIDA GPU nodes.
For Oak Ridge, there are approximately 4600 nodes, each with 2xIBM Power9 and 6 NVIDA Volta GPUs. The previous supercomputer had over 18,999 AMD/NVIDA nodes. Even with far fewer nodes, the combination of Power9 and NVIDA really boosts performance: from 27-pet flops to 200-pet flops.
To run PowerAI, you have to download Ubuntu 16.04 for the IBM Power8, as well as the PowerAI package. These links can be found here.
The price for an S822LC (8355 GTB) with 16 Power8 cores, 256GB internal memory and 2 NVIDA GP100 GPU is around 350,000 NOK.
