Ioannis,
### What version of Open MPI are you using? (e.g., v1.10.3, v2.1.0, git
branch name and hash, etc.)
### Describe how Open MPI was installed (e.g., from a source/
distribution tarball, from a git clone, from an operating system
distribution package, etc.)
### Please describe the system on which you are running
* Operating system/version:
* Computer hardware:
* Network type:
also, what if you
mpirun --mca shmem_base_verbose 100 ...
Cheers,
Gilles
