While we chose MVAPICH2 for implementing our designs, any MPI

./examples/spc_example.c or ./test/spc/spc_test.c to see how to use this.

Hi,
Do you get similar results when you repeat the test? Another job could
have interfered with your run.

Hi
I am using OSU microbenchmarks compiled with openMPI 3.1.6 in order to
check/benchmark
the infiniband network for our cluster.
For that i use the collective all_reduce benchmark and run over 200 nodes,
using 1 process per node.
And this is the results i obtained 😎

Hi
I tried to install OpenMPI v 4.0.1 on our Debian cluster using Infiniband
network with following dev_info:
hca_id: mlx4_0
1) I first tried to install openMPI without UCX framework and i runs prefectly
as before
just need to add
>export OMPI_MCA_btl_openib_allow_ib=1
to remove the warning l
12 matches
