Using NVIDIA HPC

To use NVIDIA HPC in our HPC Cluster, one needs to load the corresponding module. To know the dependencies of NVIDIA HPC, run

module spider nvhpc

Load the appropriate module (version):

module load nvhpc/22.2

Copy the sample C++ source code "sortParallel.cpp" from /usr/local/doc/NVHPC to your home directory:

cp /usr/local/doc/NVHPC/sortParallel.cpp .

Request a GPU node:

srun -p gpu --gres=gpu:1 --mem=8gb --pty bash

Load nvhpc module:

module load nvhpc

Compile the code using nvhpc:

nvc++ -stdpar -o cusort sortParallel.cpp

Run:

time ./cusort

output:

Testing with 1000000 doubles...
