Hi Richard,
the check for the GNU compilers is mostly a historic relic. We haven't
done any systematic tests with other compilers, so that test has just
remained in place.
It would certainly be good if you could update the check to also work
well with the default environment on Summit.
Thanks and best regards,
Karli

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
