Building VASP on Kestrel#

Sample makefiles for vasp5 (cpu version) and vasp6 (cpu and gpu versions) on Kestrel can be found in our Kestrel Repo under the vasp folder.

Compiling your build#
Build recommendations for VASP 
#Make sure to salloc to a gpu node
salloc -N 1 --time=01:00:00 --account=hpcapps --reservation=<friendly-users-reservation> --gres=gpu:h100:4 --partition=gpu-h100

# Load appropriate modules for your build. For our example these are:
module restore
source /nopt/nrel/apps/gpu_stack/env_cpe23.sh
ml gcc
ml PrgEnv-nvhpc
ml cray-libsci/23.05.1.4
ml craype-x86-genoa

make DEPS=1 -j8 all
Running your build#
Sample job script: How to run your own build

See sample jobs scripts above for sbatch and export directives to request full or shared gpu nodes.

# Load modules appropriate for your build. For ours these are:
module restore
source /nopt/nrel/apps/gpu_stack/env_cpe23.sh
ml gcc
ml PrgEnv-nvhpc
ml cray-libsci/23.05.1.4
ml craype-x86-genoa

# Export path to your buid
