Eduardo,
The first part of the configure command line is for an install in /usr, but
then there is ‘—prefix=/opt/openmpi/4.0.0’ and this is very fishy.
You should also use ‘—with-hwloc=external’.
How many nodes are you running on and which interconnect are you using ?
What if you
mpirun —mca pml ob1 —mca btl tcp,self -np 2 ./a.out
Cheers,
Gilles
