We have kept mpich2-maint for a long time now to allow for transitioning
users (since many versions ago, MPICH2 README asked them to email
mpich2-maint). Direct emails to mpich2-maint have been discouraged for
a long time, but somehow we are not able to do that ourselves (so
telling users not to do that doesn't make sense).
Now that this transition period is over, I'm planning to direct all
emails sent to mpich2-maint, to mpich-discuss (trac emails go to
mpich2-bugs, not mpich2-maint).
If you don't want this change to happen, shout now.

I've added the mpich-bibs.bib file to the radix-materials repo (https://svn.mcs.anl.gov/repos/radix-materials) so that we can maintain it. Please use this version as the authoritative version.
Thanks,

From the meetings website [1], the many tickets appear to be up for votes. See the end of this email for a cut-and-paste list from the agenda.
I am currently planning on voting YES for everything except for the Fault Tolerance tickets (#323, #326, #327) and the Helper Threads ticket (#217). Rolf's slides indicate that there may be some other FT tickets up for 1st votes, namely #324. I will vote NO on all of the tickets explicitly enumerated in this paragraph.
Are we all on the same page here w.r.t. ANL's position in the Forum?

Do we have any kind of regression test suite for hydra? Hydra has a ton of different configurations and features, and I feel like we've been absurdly lucky not to have more frequent regressions than we already have.
