Fellow PETSc developers,
If I try to configure PETSc with CUDA support on the ORNL Summit system using
non-GNU compilers, I run into an error due to the following code in
packages/cuda.py:
def configureTypes(self):
import config.setCompilers
if not config.setCompilers.Configure.isGNU(self.setCompilers.CC, self.log):
raise RuntimeError('Must use GNU compilers with CUDA')
...
Is this just because this code predates support for other host compilers with
nvcc, or is there perhaps some more subtle reason that I, with my inexperience
using CUDA, don't know about? I'm guessing that I just need to add support for
using '-ccbin' appropriately to set the location of the non-GNU host compiler,
but maybe there is something that I'm missing. I poked around in the petsc-dev
mailing list archives and can find a few old threads on using non-GNU
compilers, but I'm not sure what conclusions were reached.
Best regards,
Richard
