No, they didn't. I re-ran them to just time autoreconf (is there a way

Jeff,
Is that EuroMPI2010 ob1 paper publicly available? I get involved in various
NUMA partitioning/architecting studies and it seems there is not a lot of
discussion in this area.

I don't have huge experience
I just commited the very last modifications of ROMIO (mpich2-1.3rc1)
into bitbucket.

Some of you may be unaware that recent versions of automake can run in
parallel. That is, automake will run in parallel with a degree of (at most)
$AUTOMAKE_JOBS. This can speed up the execution time of autogen.pl quite a bit
on some platforms. On my cluster at cisco, here's a few quick timin
Thanks Lisandro!
I filed https://svn.open-mpi.org/trac/ompi/ticket/2594 about this.

crcpw is a wrapper around the PML to support coordinated checkpoint restart. It
mostly just replays the call to the 'crcp' framework that tracks the signature
of messages traveling through the system.
If you are not using the C/R feature, then I would not worry about the crcpw

Oops! I messed this up:
bfo is the one I meant to write up there -- it's a fork of ob1; it adds
failover semantics.
I don't know exactly what crcpw is -- I suspect this is
