Error when loading the 21.5 BYO module:

module add nvidia/nvhpc-byo-compiler/21.5
Module ERROR: can't read "nvcompdir": no such variable
  In '/opt/modulefiles/nvidia/nvhpc-byo-compiler/21.5'
  Please contact <root@localhost>

Very sorry about this. This was an enhancement for 21.5 that crept into a module file it shouldn’t have. We will fix this for the 21.7 release.

In the meantime, you can fix the module file by simply deleting the lines that refer to $nvcompdir:

prepend-path PATH $nvcompdir/extras/qd/bin

prepend-path CPATH $nvcompdir/extras/qd/include/qd

prepend-path LD_LIBRARY_PATH $nvcompdir/extras/qd/lib

Where do we ask questions about the packages bundled in HPC SDK? For starters:

  • Does InfiniBand work with the MPI that ships with HPC SDK? The openib btl doesn’t seem to be working.
  • When using nvblas with scalapack that ships with HPC SDK, I get incorrect answers. How to troubleshoot?


Hi, will the new version on Windows10 be available this year? Thanks!
