7. Allocate a node.
Note: For ISC24 use only RM partition with up to 4 nodes allocation, or the GPU partition with single GPU allocation.
Here is an example to allocate single node. use -A with the project ID
Installing and using HPC-X (Example)
Download the above file.
tar xjfp hpcx-2.13.1.tbz
module use <path to hpcx-2.13.1>/modulefiles
module load hpcx
