NERSC PMEMD Benchmark Performance Data

The first table lists processing rates (in GFLOPS/s) and corresponding machine efficiences. Floating-point operation counts were obtained using the NERSC IPM utility on Seaborg. Benchmark runtimes are presented in the second table. Machine names are hyperlinks to machine descriptions.

PMEMD uses strong scaling.

All runs were conducted during normal production periods while a full workload was running. This can introduce a variability in the measurement that differs from machine to machine.
