Hello, Thank for the advice, it works with NFS !
But : 1) it doesn't work anymore, if I remove --prefix /Network/opt/openmpi-1.4.2 (is there a way to remove it on OSX, already declared ?) 2) I must use the option -static-intel at link else i have a problem with libiomp5.dylib not found Christophe Message: 3 List-Post: users@lists.open-mpi.org Date: Sat, 15 May 2010 08:14:42 -0400 From: Jeff Squyres <jsquy...@cisco.com> Subject: Re: [OMPI users] openmpi + share points To: "Open MPI Users" <us...@open-mpi.org> Message-ID: <6b0cfd91-0e2a-498c-97bd-c6eb974f9...@cisco.com> Content-Type: text/plain; charset=us-ascii Sorry for the delay in replying. It is probably much easier to NFS share the installation directory so that the exact same installation directory is available on all nodes. For example, if you installed OMPI into /opt/openmpi-1.4.2, then make /opt/openmpi-1.4.2 available on all nodes (even if they're mounted network shares). Can you try that?
