Subject: [OMPI users] libibverbs and openmpi 1.2.6
From: Samuel Sarholz (sarholz_at_[hidden])

we have a some issues with the openmpi 1.2.6 and libibverbs.

We have some machines with Infiniband and some without.
We compiled openmpi with IB support.
With OpenMPI 1.2.5 it was no problem running that version on the
machines without IB.
However with 1.2.6 the library libibverbs is linked which doen't exist
on some of the machines.

Is there a way to get programs compiled on a IB machine running them on
machines without IB? (remove the dependency to libibverbs from openmpi
