Subject: Re: [OMPI users] Concerning infiniband support

Hi,

Besides all these advices have been given, you may need to use --prefix
in configure script to override default installation directory since you
don't have root account. Also you might want to look at MVAPICH as an
alternative, an variant of MPICH2 that supports infiniband.

good luck,
