Re: [OMPI devel] Branching for 1.5.0

2009-05-05 Thread Jeff Squyres
I think we're all amenable for this for the v1.5 branch. Let's do the usual -- bring it in on the trunk, smooth out any issues that arise, and, if we've branched for v1.5 already, bring it over when it's ready. If not, it'll just be included in the branch. So either way, it'll get into v1.

[OMPI devel] renaming / v1.5 branch

2009-05-05 Thread Jeff Squyres
For those not on the call today: 1. Greg's renaming stuff is coming in tomorrow. We're intentionally breaking the "don't cause autogen-worthy changes in the middle of the workday" guideline so that others can test manually during the day. 2. There appears to be no pressing reason to branch

It took a little longer than expected, but here's the reply from a friend who works on Apple's C++ compilers (Doug G.; he's previously posted on this list): - This is more sticky than I expected. My general feeling is that GCC 4.1 is being overly eager in producing this warning: yes, OMPI

Hmm -- this looks like a different error to me. The <1% error rate sm error we were seeing was in MPI_INIT. This looks like it is beyond MPI_INIT and in the sending path...? On May 4, 2009, at 11:00 AM, Eugene Loh wrote: Ralph Castain wrote: > In reviewing last night's MTT tests for the 1

Different from what? You and Terry saw something that was occurring about 0.01% of the time during MPI_Init during add_procs. That does not seem to be what we are seeing here. But we have seen failures in 1.3.1 and 1.3.2 that look like the one here. They occur more like 1% of the time and
