Sparse Matrix-Matrix Multiplication Benchmark Code for Intel Xeon and Xeon Phi

This repository contains the benchmark code supplementing my blog post on a matrix-matrix multiplication benchmark on Intel Xeon and Xeon Phi.

Build and Run

The following instructions are for *nix-based systems. The code should also work on Windows, but is not tested.

First run the script

$> ./init.sh

to download and extract the sparse matrices. This will pull about 350MB of data and thus may take a while.

Second, run the executables via

$> ./run_mkl_xeon
$> ./run_mkl_knl 0    # for DDR4
$> ./run_mkl_knl 1    # for MCDRAM
$> ./run_mkl_knc

This assumes that your Intel compiler variables are set accordingly. Note that for the Xeon Phi KNC you have to cross-compile on the host and run the script on the device.

The folder results/ contains the results I obtained on different systems. Feel free to paste your results in there in replot the graphs via

$> Rscript plot.R

The free open source statistics package R is required for the plots.
