Leo,
Thanks for the info. That is interesting. And yes, Having a CUDA aware MPI
API list would be very useful.

Hi Junchao,
First, for your second question, the answer is here:
Note that it is not advisable to run autogen from a distribution tarball.
Specifically: we include the autogen script for advanced users who want to
tweak their own Open MPI copy (without cloning from git), but 99.99% of users
can just run "./configure ..." directly (without first running
Do not use Open MPI v2.0.x -- it's ancient.
You should probably use Open MPI v3.1.x or v4.0.x.

Is there any chance that the fact that Riddhi appears to be trying to execute
an uncompiled hello.c could be the problem here?

Hi,
Evan after recompiling OpenMPI with -fdefault-real-8, it fails with same
error.
It seems to me that, it's an issue with OpenMPI itself, because:
Intel MPI + gnu compiler --- works
Intel MPI + intel compiler --- works
Open MPI + gnu compiler --- fails
Open MPI + AOCC compiler --- fails
Thanks, but this is not really helping.
Could you please build a Minimal, Reproducible Example as described at
https://stackoverflow.com/help/minimal-reproducible-example ?
Cheers,

I am not questioning whether you are facing an issue with Open MPI or not.
I am just asking for "the same application" (read minimal source code)
so I can reproduce the issue, investigate it and hopefully help you.
Meanwhile, try rebuilding Open MPI with '-fdefault-real-8' in your
FCFLAGS (since
Hi,
I've tried both gcc-8.1.0 and AOCC-2.0 compilers with openmpi-3.1.1. It
fails for both the compilers.
Posted error message was from OpenMPI-3.1.1 + AOCC-2.0 compiler.
To cross-check whether it is problem with OpenMPI or the base compiler,
compiled the same application with Intel MPI using
One more thing ...
Your initial message mentioned a failure with gcc 8.2.0, but your
follow-up message mentions LLVM compiler.
So which compiler did you use to build Open MPI that fails to build your test ?

Hi,
OpenMPI is configured as follows:
export CC=`which clang`
export CXX=`which clang++`
export FC=`which flang`
export F90=`which flang`

Hi,
Can you please post a full but minimal example that evidences the issue?
Also please post your Open MPI configure command line.
