Hi Eduardo,
The OFI MTL got some new features during 2018 that went into v4.0.0 but are not
backported to older OMPI versions.
What version of libfabric are you using and where are you installing it from?
I will try to reproduce your error. I'm running some quick tests and I see it
working:
BTW, just to be explicit about using the psm2 OFI provider:
/tmp> mpirun -np 2 -mca mtl ofi -mca pml cm -mca mtl_ofi_provider_include psm2
./a
Hello World from proccess 0 out of 2
This is process 0 reporting::
Hello World from proccess 1 out of 2
Process 1 received number 10 from process 0
