Hi,
I’m trying to do some RoCE benchmarking on a cluster with Mellanox HCA’s:
02:00.0 Ethernet controller: Mellanox Technologies MT27800 Family [ConnectX-5]
MLNX_OFED_LINUX-4.4-2.0.7.0
I’m finding it quite challenging to understand what btl is actually being used
based on openmpi’s debug output.
I ran a simple spawn test - you can find it in the OMPI code at
orte/test/mpi/simple_spawn.c - and it worked fine:
$ mpirun -n 2 ./simple_spawn
[1858076673:0 pid 19909] starting up on node Ralphs-iMac-2.local!
[1858076673:1 pid 19910] starting up on node Ralphs-iMac-2.local!
1 completed MPI_Init
