Re: [OMPI devel] Warnings in v1.7.4: rcache
Yes, that is from one of my CMRs. I always configure with -enable-picky but that did not pick up this warning. I will fix this in the trunk in the morning (watching the Red Sox right now :)) and then file CMR to bring over.

Ralph, et al., Kathy Yelick is featured in this month's ACM Member News sidebar (p. 17). It also turns out she will be giving a lecture at SC13. http://sc13.supercomputing.org/content/sc13-feature-acm-athena-lecturer-katherine-yelick Check it out.

Re: [OMPI devel] [OMPI svn] svn:open-mpi r29489 - trunk/orte/mca/plm/base
I reverted this changeset from the trunk as it incorrectly re-added the
local coprocessor data to the HNP's hash table. This is already being done
in the ess/hnp module, and there is no value in duplicating it again every
time a daemon calls back.
As noted in the revert comment, if we want host daemons to retain their
coprocessor info in a hash table, then we need to do that somewhere else,
not where this was done. At this time, I don't see the daemons using that
info anywhere.

[OMPI devel] .mailmap added for github mirror
Based on discussion with Mellanox around the recent GitHub mirror updates, I've added a .mailmap file in r29494. It helps address two goals: 1) To be able to fix misspelled names without rewinding the Git history. 2) To be able to add email addresses incrementally without rewinding Git history. Mellanox would like email addresses so that they can automatically send build failure emails from their Jenkins continuous integration server. The initial version only contains email addresses for Cisco contributors. I've put commented-out templates for all other contributors listed in the AUTHORS file. If you are a contributor and you would like to opt-in to having your email address listed in this format, please follow the editing instructions listed in that file on the trunk. At some point I'll CMR the latest state of the file to the v1.7 branch as well. For more information about git's usage of the .mailmap file, see the man page for git-shortlog: https://www.kernel.org/pub/software/scm/git/docs/git-shortlog.html -Dave
