Great it is finally working !
nvml and opencl are only used by hwloc, and i do not think Open MPI is
using these features,
so i suggest you go ahead, reconfigure and rebuild Open MPI and see how
things go

Hi Gilles,
Yes, you're right. I wanted to double check the compile but didn't notice I
was pointing to the exec I compiled from a previous Make.
mpicc now seems to work, running mpirun hello_c gives:
Hello, world, I am 0 of 4, (Open MPI v3.0.0, package: Open MPI
tjim@DESKTOP-TA3P0PS Distribution
Was there an error in the copy/paste ?
The mpicc command should be
mpicc /opt/openmpi/openmpi-3.0.0_src/examples/hello_c.c

The issue is related to openCL, not NVML.
So the correct export would be "export enable_opencl=no" (you may want
to "export enable_nvml=no" as well).

A few things:
0. Rather than go a few more rounds of "how was Open MPI configured", can you
send all the information listed here:

That will tell us a lot about exactly how your Open MPI was configured,
installed, etc.

Hi,
I tried as you suggested: export nvml_enable=no, then reconfigured and ran
make all install again, but mpicc is still producing the same error. What
should I try next?
Many thanks,

Tim,
do that in your shell, right before invoking configure.
export nvml_enable=no
./configure ...
make && make install
you can keep the --without-cuda flag (i think this is unrelated though)

Dear Gilles,
Thanks for the mail - where should I set export nvml_enable=no? Should I
reconfigure with default cuda support or keep the --without-cuda flag?
Kind regards,

Tim,
i am not familiar with CUDA, but that might help
can you please
export nvml_enable=no
and then re-configure and rebuild Open MPI ?
i hope this will help you

In summary, I have attempted to install OpenMPI on Ubuntu 16.04 to the

added the following to my .bashrc:
export PATH="/opt/openmpi/openmpi-2.1.0/bin:$PATH"
MPI_DIR=/opt/openmpi/open
Thanks for the thoughts, I'll give it a go. For reference, I have installed
it in the opt directory, as that is where I have kept my installs
currently. Will this be a problem when calling mpi from other packages?
Thanks,

LIke before: can you compile and run mpihello.c this time – all as ordinary
user in case you installed the Open MPI into something like
$HOM
Dear Reuti,
Thanks for the reply. What options do I have to test whether it has
successfully built?
Thanks and kind regards.

Hello,
Thanks for your message. I'm trying to get this to work on a single
machine. How might you suggest getting OpenMPIworking without python and
CUDA? I don't recall setting anything for either, as the only command I had

Hello,
I have been having some issues with trying to get OpenMPI working with
mpi4py. I've tried to break down my troubleshooting into a few chunks
below, and I believe that there are a few, distinct issues that need
solving.
