Download

Download CUDA Accelerated Linpack for Linux64 (hpl-2.0_FERMI_v15.gz) from NVIDIA Developer Portal

untar hpl-2.0_FERMI_v15.gz
cd hpl-2.0_FERMI_v15

Environment

This is to make sure that you don't have any issues in compiling HPL on your system because they have hard-coded in the /usr/local/cuda/ directory as the default directory in all of their makefiles. You can go through them all and change it, but it is just easier to create a link to where you have it installed.

cd /usr/local
ln -s /shared/apps/cuda/cuda-5.0 cuda

Build

module load cuda/5.0
module load openmpi/1.6.3-gpu
make arch=CUDA

Modulefile

File location: /shared/modulefiles/gpu/linpack
File name: hpl-2.0_FERMI_v15
