Download the source.

cd ~
wget https://software.sandia.gov/hpcg/downloads/hpcg-2.4.tar.gz
tar -xf hpcg-2.4.tar.gz
cd hpcg-2.4
mkdir build

Edit the Makefile to include the -xHost compiler flag:

vim setup/Makefile.MPIICPC_OMP

Compile the benchmark:

cd build
../configure Makefile.MPIICPC_OMP
make

The benchmark can be run using MPI, OpenMP or a hybrid of the two. Two specify the number of desired OpenMP threads, set the environment variable:

OMP_NUM_THREADS=<N>

The problem size can be increased in the hpcg.dat file. To run the benchmark:

mpirun -n <N> -hostfile <HF> ./xhpl

Experimentation should be conducted to determine which approach yields the best performance.
