[OMPI devel] Binding with --oversubscribe in 2.0.0

Hi, One of our users has noticed that binding is disabled in 2.0.0 when --oversubscribe is passed, which is hurting their performance, likely through migrations between sockets. It looks to be because of 294793c (PR#1228). They need to use --oversubscribe as for some reason the developers decided

Paul, you can download a patch at https://patch-diff.githubusercontent.com/raw/open-mpi/ompi-release/pull/1336.patch (note you need recent autotools in order to use it) Cheers, Gilles On 8/23/2016 10:40 PM, r...@open-mpi.org wrote: Looks like Solaris has a “getupeercred” - can you take

Jeff, Correct, the latest GA release is 12.5 and it correctly handles -m32 where 12.4 failed. -Paul [Sent from my phone] On Tuesday, August 23, 2016, Jeff Squyres (jsquyres) wrote: > Paul -- > > 12.5 is the latest (last?) version of the Oracle compilers, right? > > If that's correct: are you say

Re: [OMPI devel] [2.0.1.rc1] dlopen_test crashes with xlc and studio compilers

Paul -- 12.5 is the latest (last?) version of the Oracle compilers, right? If that's correct: are you saying that 12.5 (GA/not beta) *does* handle the dlopen test with -m32 properly? If so, it sounds like we should amend README to say that we support 12.5 and nothing earlier (given that 12.5 i

Re: [OMPI devel] Performance analysis proposal

Hello, I just came over this and would like to contribute some results from our system(s). Are there any specific configure options you want to see enabled beside --enable-mpi-thread-multiple? How to commit results? Best Christoph Niethammer - Original Message - From: "Arm Patinyasak

Re: [OMPI devel] [2.0.1.rc1] Solaris MPIX failure

Looks like Solaris has a “getupeercred” - can you take a look at it, Gilles? We’d have to add that to our AC_CHECK_FUNCS and update the native sec component. > On Aug 23, 2016, at 6:32 AM, r...@open-mpi.org wrote: > > I took a quick glance at this one, and the only way I can see to get that >

Re: [OMPI devel] [2.0.1.rc1] Solaris MPIX failure

I took a quick glance at this one, and the only way I can see to get that error is from this block of code: #if defined(HAVE_STRUCT_UCRED_UID) euid = ucred.uid; gid = ucred.gid; #else euid = ucred.cr_uid; gid = ucred.cr_gid; #endif #elif defined(HAVE_GETPEEREID) pmix_output_v

Re: [OMPI devel] [2.0.1.rc1] runtime failure on MacOS 10.6

Actually, I found that we already dealt with this, but the version in the 2.0.1 branch didn’t include the update. I’ll see what else is missing and ask that it be brought across. Thanks Paul Ralph > On Aug 22, 2016, at 9:25 PM, r...@open-mpi.org wrote: > > Hmmm...okay. I guess we’ll replace th

Re: [OMPI devel] Open MPI 2.0.0: Fortran with NAG compiler (nagfor)

Gilles, Jeff, In Open MPI 1.6 days, MPI_ARGVS_NULL and MPI_STATUSES_IGNORE were defined as double precision and MPI_Comm_spawn_multiple and MPI_Waitall etc. interfaces had two subroutines each. https://github.com/open-mpi/ompi-release/blob/v1.6/ompi/include/mpif-common.h#L148 https://github

Re: [OMPI devel] stdin issue with master

Thanks Ralph, I noticed an other issue (hang) with echo hello | mpirun -stdin all -np 1 cat (any number of tasks can be used) I guess this is a pretty uncommon usage, so fixing this could be low priority Cheers, Gilles On Tuesday, August 23, 2016, r...@open-mpi.org wrote: > Fixed in 921023

Thanks Paul, at first glance, something is going wrong in the sec module under solaris. I will keep digging tomorrow Cheers, Gilles On Tuesday, August 23, 2016, Paul Hargrove wrote: > On Solaris 11.3 on x86-64: > > $ mpirun -mca btl sm,self,openib -np 2 -host pcp-d-3,pcp-d-4 > examples/ring_c
