[OMPI devel] cosmetic misleading mpirun error message

Hi, Playing with the 1.10.0 (just released) build I found a cosmetic misleading error message in mpirun. If by mistake you type -hosts (with an extra "s"), the error message complains about an unknown "-o" option that is actually not being used. Typing the parameters correctly fixes the issue

? Are you doing a VPATH build, or doing the build in the repo location? Also, I assume you remembered to run autogen.pl before configure, yes? On Sep 1, 2015, at 10:11 AM, Cabral, Matias A <matias.a.cab...@intel.com<mailto:matias.a.cab...@intel.com>> wrote: Hi Gilles, I deleted everythin

[OMPI devel] orted hangs on SLES12 when running 80 ranks per node

Hi, I have hit an issue in which orted hangs during the finalization of a job. This is reproduced by running 80 ranks per node (yes, oversubscribed) on a 4 nodes cluster that runs SLES12 with OMPI 1.10.2 (I also see it with 1.10.0). I found that it is independent of the binary used (I used a

Re: [OMPI devel] psm2 and psm2_ep_open problems

Hi Howard, I suspect this is the known issue that when using SLURM with OMPI and PSM that is discussed here: https://www.open-mpi.org/community/lists/users/2010/12/15220.php As per today, orte generates the psm_key, so when using SLURM this does not happen and is necessary to set it in the

Hi Howard, Couple more questions to understand a little better the context: - What type of job running? - Is this also under srun? For PSM2 you may find more details in the programmer’s guide:

[OMPI devel] MPI_Init() affecting rand()

Hi All, Doing quick test with rand()/srand() I found that MPI_Init() seems to be calling a function in their family that is affecting the values in the user application. Please see below my simple test and the results. Yes, moving the second call to srand() after MPI_init() solves the

Re: [OMPI devel] Default tag for OFI MTL

imit via the MPI_TAG_UB. I personally would prefer a solution where we can alter the distribution of bits between bits in the cid and tag at compile time. We can also envision this selection to be driven by an MCA parameter, but this might be too costly. George. On Sat, Mar 3, 2018

[OMPI devel] Default tag for OFI MTL

Hi all, I'm working on extending the OFI MTL to support FI_REMOTE_CQ_DATA (1) to extend the number of ranks currently supported by the MTL. Currently limited to only 16 bits included in the OFI tag (2). After the feature is implemented there will be no limitation for providers that support

Hi Edgar, I also saw some similar issues, not exactly the same, but look very similar (may be because of different version of libpsm2 ). 1 and 2 are related to the introduction of the OFI BTL and the fact that it opens an OFI EP in its init function. I see that all btls call the init function
