Re: [OMPI devel] v1.8.1 release

2014-04-22 Thread Jeff Squyres (jsquyres)
I spoke with Ralph last night (he's still on vacation); there has been a change of plan. Unfortunately, the HEAD of the v1.8 branch is currently too unstable for immediate release (and we really need to do an immediate v1.8.1 release). MTT is showing a bunch of MPI-layer failures. It does not

I need the flatten datatype call for handling true rdma in the one-sided code as well. Is there a plan to implement this feature soon? -Nathan From: devel [devel-boun...@open-mpi.org] on behalf of George Bosilca [bosi...@icl.utk.edu] Sent: Monday, April 2

[OMPI devel] v1.8[.2] CMRs this week

2014-04-22 Thread Jeff Squyres (jsquyres)
Per discussion on the call today, I'm going to start RM approving some of the most obvious / clearly-needed CMRs that are now pending for v1.8.2. This mainly includes CMRs that have the potential to improve MTT scores. For example: compiler errors, obvious bugs, etc. Other CMRs can wait until

Re: [OMPI devel] Win_fence() with assertion=MPI_MODE_NOPRECEDE|MPI_MODE_NOSUCCEED

2014-04-22 Thread Nathan Hjelm
