I don't know that I'd agree with that. Would a book snob really bother to have slogged through the last few WoT books before having the author die on him? I'm not hard to entertain; if I don't like your writing, there's something SERIOUSLY wrong. I'll put up with acres of bad writing if I'm already invested in an author or story.

I'd decided that Python was to be my next learning project, but it looks like that's going on hold and I'm going to actually learn MPI. My 3D convection code is parallelized. Not massively, 12 processors (6 nodes) is typical, but it does make heavy use of MPI. I should point out that I'm not the one who originally parallelized this code. While I understand and have contributed to the C code, I've never really messed with the MPI routines. I've always been more concerneded in the science than the computing details.

But I'm getting think there's something seriously wrong with the Beowulf cluster (upsand) at work (it's old and nodes are dying and there's no funding to replace them). I don't think the problem lies with my code, but I don't know MPI well enough to really be sure that's not the case.

I expect soon to have access to the computing facilities at Berkeley, so if it's a hardware/configuration issue I'm facing, that may be solved soon. But it's clear that I should learn MPI, if I'm to continue in this field. I really do have odd gaps in my education for having the PhD. Any recommendations for resources on learning MPI? Through the UC library system, I can get access to all of the O'Reilly books online, but I welcome other suggestions.
