Eric, You are correct, our builds do not show lustre support:
MCA io: information "io_romio_user_configure_params" (value: <none>, data source: default value) So to enable this, when I build OpenMPI I should pass: --with-io-romio-flags='--with-file-system=testfs+ufs+nfs+lustre' We have Lustre, local filesystems (ufs), and NFSv3 and NFSv4 clients. So that list should be good for our site. Would this be a good recommendation for us to include in all our MPI builds?
