Quickstart guide
Environment modules
Before you start profiling with NVPROF, the appropriate module needs to be loaded.
NVPROF is part of the CUDA package, so run module avail cuda to see what versions are currently available with the compiler and MPImodules you have loaded. For a comprehensive list of Cuda modules, run module -r spider '.*cuda.*'.
At the time this was written these were:
- cuda/10.0.130
- cuda/10.0
- cuda/9.0.176
- cuda/9.0
- cuda/8.0.44
- cuda/8.0
Use module load cuda/version to choose a version. For example, to load the CUDA compiler version 10.0, do:
[name@server ~]$ module load cuda/10.0
