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

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)
Cheers,
Gilles

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,

i am not familiar with CUDA, but that might help
can you please
export nvml_enable=no

Hello,
Apologies to bring up this old thread - I finally had
a chance
to try again with openmpi but I am still have trouble
getting
it to run. I downloaded version 3.0.0 hoping it would
solve
some of the problems but on running mpicc for the previous
test case, I am still getting an undefined reference
error. I
did as you suggested and also configured it to install
without
cuda using
./configure --without-cuda
--prefix=/opt/openmpi/openmpi-3.0.0
and at the end of the summary, CUDA support shows 'no'.
Unfortunately, the error is still the same, and for some
reason, mpicc still seems to have referenced my
cuda targets.

I also attempted to test mpirun, as suggested in the

Open MPI tried to fork a new process via the "execve"

failed. Open MPI checks many things before attempting
to launch a
child process, but nothing is perfect. This error may be
indicative
of another problem on the target host, or even
something as
silly as
having specified a directory for your application.
Your job

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 $HOME/local/openmpi-2.1.1 and
set paths
accordingly. There is no need to be root to
install a
personal
Open MPI version in your home directory.
