General Info

HPC Challenge is a benchmark suite comprising 7 micro benchmarks designs to assess a number of HPC system characteristics. The suite includes HPL, DGEMM and FFT which test floating point performance. STREAM and RandomAccess are included to access memory performance. PTRANS and 'Communication bandwidth and latency' are used to assess network performance. source

Installation Guide

source Intel Compiler, MKL and MPI.

source /opt/intel/impi/ intel64
source /opt/intel/bin/ intel64
source /opt/intel/mkl/bin/ intel64

Download the source from the website:

cd ~
mkdir HPCC
tar -xf hpcc-1.5.0a.tar.gz
cd hpcc-1.5.0a

Use the Makefile which is adapted from the HPL which ships with the Intel MKL package:

cp Makefile.intel64 ~/HPCC/hpcc-1.5.0a/hpl

Make with:

make arch=intel64


Before running the benchmark, edit the hpccinf.txt file. Set appropriate N, NB, P and Q values (using the calculator linked above.)

Run the benchmark using:

mpirun -np <N> -hostfile <HF> ./hpcc

Download this script to format the output data: format.tar

./ -w -f hpccoutf.txt

Below is the result from the Dell C4130, with its 24 Haswell cores.
