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/5.0.1.035/bin64/mpivars.sh intel64 source /opt/intel/bin/compilervars.sh intel64 source /opt/intel/mkl/bin/mklvars.sh intel64
Download the source from the website:
cd ~ mkdir HPCC cd HPCC wget http://icl.cs.utk.edu/projectsfiles/hpcc/download/hpcc-1.5.0a.tar.gz 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
Benchmark
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
./format.pl -w -f hpccoutf.txt
