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?
