<p>Hi Ian,</p>
<p>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.<br>
</p>
<p>I have recompiled with the fix you mentioned but I still get the
same error.</p>
<p>Cheers,</p>
<p>Chris<br>

<p>Hi Ian,</p>
<p>thanks for your quick reply!</p>
<p>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.<br>
</p>
<p>I have tried using procs=48 and num-threads=2 but I find
the same problem.</p>
<p>As you say, I recompiled a clean config to double check.
I have also used the May 16 version but to no avail.</p>
<p>Could it be something to do with compilation, that has
gone wrong somehow, even though it finishes successfully
with done?<br>

<div>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.]</div>

<div>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.</div>

</div>
<div>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.</div>
