[yt-users] TimeSeriesData.piter() exiting early

[Nathan Goldbaum]

Hi all,

I'm processing some simulations that i have stored on Pleiades at NASA Ames.  This machine using SGI's version of MPI so it's possible that this issue is isolated to this MPI.

When I ts.piter() on this machine, it will sometimes die early, before all of the parameter files have been processed, with the following error:

MPI: MPI_COMM_WORLD rank 7 has terminated without calling MPI_Finalize()
MPI: aborting job

This particular script saves a bunch of plots to disk.  Taking a look at the list of plots that have been saved, it seems that it got about halfway through before dying.  The first ~third of the plots are all on disk, most of the middle ~third are saved although there are some missing plots, and the last ~third haven't been saved at all.

Any ideas what's going wrong here?  Is there something simple I can do to fix it?  This isn't game-ending since I can always process my data in serial but it is a bit annoying.

Cheers,

Nathan
