Hi Cameron,
No, that's *exactly* the type of error you'd expect from that. I did
not notice the mismatch. Good catch, thanks!

I've only been sparsely following this thread, but I noticed that you're running Python 2.4.2 on Kraken, whereas you're using yt in a directory labeled python2.6. Could a mismatch of python versions cause such a problem? Isn't the default version of python on kraken 2.6.4? You could type "which python" to find out which version of python you're using, but 2.6.4 is in:
/sw/xt/python/2.6.4/sles10.1_gnu4.1.2//bin/python
If you want to switch to using 2.6.4, you could type:
$ module load python/2.6.4
Matt or Esteban, could a mismatch of python versions cause this problem in yt? Or am I totally off-base here?

Stephen,
This was being run as a batch job, 2 cores/node on 256 cores total.
I just tried loading up yt on the login node of Kraken, and hit some problems. Does any of this illuminate things?

Brian & Matt,
Hello from Boulder! I'm probably not going to be able to follow this up very quickly. Until tomorrow my internet access is limited to cafés and we have lots of other things to get done!
I'd suggest moving it out of the way for now and continuing on. Stephen, if you're listening, is it possible that the .yt file has had a ridiculous number of HDF5 groups made, which is confusing and overflowing h5py?
Nothing that I've added to yt makes use of the .yt file, so the various tools I wrote Brian mentioned shouldn't affect it. One thought is I wonder if there are memory limits on the login nodes on Kraken, and if this is being hit? Brian, where you trying this on the login node, and if so, can you try it in an interactive session (one node will suffice).
