Turning off the pesky MPI_INSTRUMENTATION flag since it spits out a ton of files into the run directory (one for each MPI processor) upon completion. Also document it and how to turn it back on in comments and in docs.
UPDATE1: updated to remove the #define MPI_INSTRUMENTATION from the source, and documented how to enable it through the docs (consistent with the comments I received here).
It probably should be, yes, but I honestly didn't think we even needed it at all. Sam and my performance tools cover most of this stuff, and I was just removing it from default (and documenting it) in hopes that we'd remove it entirely in a newer version of enzo.
Nathan Goldbaum makes a very valid point in the IRC channel, in that why don't we remove this module entirely? There are lots of "#ifdef MPI_INSTRUMENTATION" commands littering the code, and if no one is using this functionality (largely because of the reasons I address in the documentation in the PR), then why not just rip it out instead of leaving it around?
If there is functionality in these tools that isn't in the stuff you and Sam wrote, you should leave it in. When the functionality is totally covered, then I would vote for pulling it out. Just because it isn't used by people who are on IRC this evening doesn't mean it isn't useful
OK, I will pull out the comment in the source, and just leave the docs with how to enable it through editing one's makefile. We can look at fully reproducing this functionality in a future version of chronos.
