HPCG 3.1 Binary for NVIDIA GPUs Including Pascal
2017-04-08

This release contains additional optimizations that improve performance for ISC 2017 runs.

This new binary supports CUDA 8.0 and the new Tesla Pascal (sm 6.0). The binary also works for Kepler (sm 3.5) and Maxwell (sm 5.0).

It requires Open MPI 1.10.2 and GCC 4.8.5

HPCG 3.0 Binary for NVIDIA GPUs Including Pascal
2016-10-20

This new binary supports CUDA 8.0 and the new Tesla Pascal (sm 6.0). The binary also works for Kepler (sm 3.5) and Maxwell (sm 5.0). Additionally, there is a better "read me" and example files.

It requires Open MPI 1.6.5 and GCC 4.8.5

HPCG 3.0 Binary from NVIDIA Optimized for NVIDIA GPUs (bugfix)
2015-11-28

This is a bugfix to the binary-only code optimized by NVIDIA. It requires CUDA 6.5 and OpenMPI 1.6.5 produced with GCC 4.8.2.

The previous code had a memory allocation problem on more than 27 MPI ranks.

HPCG 3.0 Reference Code
2015-11-11
Features include:
  • Problem generation is a timed portion of the benchmark. This time is now added to any time spent optimizing data structures and counted as overhead when computing the official GFLOP/s rating. The total overhead time is divided by 500 to amortize its cost over 500 iterations.
  • Added memory usage counting and reporting.
  • Added memory bandwidth measurement and reporting
  • Added a "Quick Path" option to make obtaining results on production systems easier. With this option, obtaining a rating will take only a few minutes. This option also makes profiling and debugging easier. The Quick Path option is invoked by setting the run time to zero, either in hpcg.dat or by using the --rt=0 option.
  • Added a command line option (--rt=) to specify the run time.
  • Made a few small changes to support easier builds on MS Windows.
  • Changed the way the residual variance is computed to make sure it is zero if all residual values are identical.
  • Changed the order of array allocation in the reference code in order to improve performance.
  • Set the minimum iteration count for the optimized run to be the same as what is used in the reference run.
