HPC LINPACK benchmark


  1. Intro
  2. HPL + Intel MKL + Intel MPI
  4. HPL + GotoBLAS2 + Open MPI

HPL is a portable implementation of HPLinpack used to provide data for the Top500 list .
To get best result in flops, I have tried different combinations: linear algebra libraries + MPI library + compiler.
I have used Intel CPUs and I got best results with MKL + Intel MPI + icc.
Below I'll show how to compile and run LINPACK benchmark with different libraries.
