June 2017 Results

Here are the results for the fourth order (operators.fv4.c) HPGMG-FV implementation (v0.3). Each machine was allowed to use any amount of memory per node, but three problem sizes were benchmarked: h(max), 2h(max/8), and 4h(max/64). Note, 'OMP' represents the number of OpenMP (or other) threads per process while 'ACC' represents the number of accelerators per process.  Multiple entries represent baseline and optimized implementations.

Currently, machines are ranked based on peak DOF/s (almost invariably problem size h). Nevertheless, we are considering alternate metrics such as the sum, mean, geometric mean, and median. Feedback from the community is welcome. Note, due to scheduling and allocation limitations, some machines were evaluated at reduced concurrency.
