Re: [OMPI devel] [OMPI users] bus error with openmpi-1.8.2 and gcc-4.9.0

[Kawashima, Takahiro]

Hi Siegmar, Ralph,

I forgot to follow the previous report, sorry.
The patch I suggested is not included in Open MPI 1.8.2.
The backtrace Siegmar reported points the problem that I fixed
in the patch.

  http://www.open-mpi.org/community/lists/users/2014/08/24968.php

Siegmar:
Could you try my patch again?

Ralph (or someone committer):
Open MPI 1.8 needs custom patch that I posted. See my previous mail.
Could you review it and commit it to v1.8 branch?

Regards,
Takahiro

[OMPI devel] Migrating Trac wiki and tickets to Github

[Jeff Squyres (jsquyres)]

As part of moving the final OMPI SVN repo to Github, we're also converting the 
Trac wiki and tickets.

I have a first attempt at converting the OMPI trac wiki to Github's Markdown:

   https://github.com/jsquyres/ompi-test/wiki

*** Note: there's a lot of stale content there -- because there's a lot of 
stale content on the Trac wiki.  I really didn't make an effort to update any 
stale (Trac) content, other than adding a small number "this page needs to be 
re-written for git/github.  The intent here is to make sure that there are no 
egregious Trac->Github wiki conversion errors.

Please feel free to make any changes/updates you want -- it's easy to move this 
wiki to its final location (i.e., when we establish the actual/final OMPI 
Github repo).

(ticket conversion is still in the works)
