Hi Sam,
I'm running the script using
srun pyyt ptest.py --parallel
That could well be picking up the system mpirun rather than the mpi that YT
was built with - I hadn't considered that. I'll check that.
The traceback is at the link below.
http://paste.yt-project.org/show/4174/
The version of YT is the dev version - that's what's sourced when the batch
script is run. I've tried with the stable version as well and got the
same result. I think you might be on to something with the mpirun library
issue though.
Thanks for the tip!
John
