NERSCPowering Scientific Discovery Since 1974



The Crossroads/N9 DGEMM benchmark is a simple, multi-threaded, dense-matrix multiply benchmark. The code is designed to measure the sustained, floating-point computational rate of a single node.

Required Problem Sets

The DGEMM benchmark shall be used to benchmark each type of node intended for computation in the proposed system. If a given node has configurable options, the benchmark will be used to report the performance of each configuration.
