Power Profiling Shows Simple Changes To Save Megawatts of Power On Leadership Supercomputers
A challenge with profiling applications lies in how to interpret the profile results. In particular, most programmers do not give the power profile plots more than a cursory glance. Following is an example waterfall plot showing the power utilization for an NWChem run on Intel Xeon Phi coprocessors: My recent column in Scientific Computing, "Using Profile Information for … [Read more...]
Preparing For Knights Landing – Stay in HBM Memory
NERSC published an informative preparatory article for programming the forthcoming Cori supercomputer that notes each Intel Xeon Phi “Knight’s Landing” (KNL) devices will be running in a “self-hosted” mode, meaning that there will be no host/traditional processor. Everything - including the operating system - will run on KNL. This eliminates concerns about data movement as … [Read more...]
