Re: [OMPI users] Using OSU benchmarks for checking Infiniband network

do some debugging / improvement right? Or is it meant for users too? If it is the case, how as user can i make use of MPI_T interface to find out if the fabric itself ( system ) has a problem ( and not the MPI implementation on top of it)? Cheers, Denis

Re: [OMPI users] Using OSU benchmarks for checking Infiniband network

I have seen in OSU INAM paper: " While we chose MVAPICH2 for implementing our designs, any MPI runtime (e.g.: OpenMPI [12]) can be modified to perform similar data collection and transmission. " But i do not know what it is meant with "modified" openMP

Hi Joseph Looking at the MVAPICH i noticed that, in this MPI implementation a Infiniband Network Analysis and Profiling Tool is provided: OSU-INAM Is there something equivalent using openMPI ? Best Denis From: users on behalf of Joseph Schuchart via

Re: [OMPI users] Using OSU benchmarks for checking Infiniband network

Hi I do not have so much experience with MVAPICH. Since we work with singularity container, i can create a container and install this version to compare. Cheers, Denis From: users on behalf of Joseph Schuchart via users Sent: Tuesday, February 8, 2022 4

Hi When i repeat i always got the huge discrepancy at the message size of 16384. May be there is a way to run mpi in verbose mode in order to further investigate this behaviour? Best Denis From: users on behalf of Benson Muite via users Sent: Monday
