Results for HPL on GPU

  • CentOS 7.1 - Kernel 3.10.0-229.20.1.el7.x86_64
  • CUDA-7.5
  • OpenMPI 1.8.5
  • Intel Compiler and MKL 2013_3.174
Some observations from runs with 128GB RAM:
  • A larger N value allows for a larger DGEMM_SPLIT value.
  • Performance suffers significantly when using large N values 100k+ with low core count's per GPU (<3).
  • In some instances oversubscribing cores per GPU will offer a performance boost.
  • The N values for the 128GB runs were the maximum obtainable for that particular GPU configuration
