Hi Ian,
thanks for spotting that. Unfortunately there is only the hwloc
directory in external. There is an MPI file (just called MPI) in the
done directory.
I have recompiled with the fix you mentioned but I still get the same error.
Cheers,
Chris

Hi Ian,
thanks for your quick reply!
There are a couple of other guys here who have successfully used the
toolkit with this version of openmpi, so I'm not sure if this is at
fault. There is not another version of openmpi available currently on
the cluster, but I could ask for this to be remedied.
I have tried using procs=48 and num-threads=2 but I find the same
problem.
As you say, I recompiled a clean config to double check. I have also
used the May 16 version but to no avail.
Could it be something to do with compilation, that has gone wrong
somehow, even though it finishes successfully with done?
Is it possible that it is building and using its own copy of OpenMPI?
The build system is "clever", and the logic for when it decides to do
this seems a bit flaky. [I would be a lot happier if it only built a
library from the bundled source if it was explicitly asked for in the
optionlist with a BUILD setting, not as a fallback to something going
wrong when trying to use the settings the user has given.]
I noticed that you have
MPI_DIR = /apps/libs/openmpi/1.8.8-intel16.0.1/lib
in the optionlist, which is wrong; it should not have the "lib" on the
end. I didn't think anything of it at the time, since you were
specifying the other directories. But maybe the MPI thorn is deciding
that since it can't find a valid MPI installation, it will helpfully
decide to build OpenMPI for you. This version may then conflict with
the rest of the configuration.
Can you look and see if there is a built version of OpenMPI in the
config? I think it would be in configs/<config>/scratch/external.
