[mvapich-discuss] segmentation fault

[Hoot Thompson]

A little background, I've been working with Mellanox to get SR-IOV 
working between two Virtual Machines (VM). As of today, I have two real 
machines each with a VM and a virtual IB connection up between them. 
Logged into one of the VMs, I can ping and run the rdma_bw and rdma_lat 
tests between the VMs just fine. Attempts to run osu_bw (compiled with 
the Intel compiler), fails with the following................


[root at penguin1-vm1 mvapich2-1.8-r5435]# mpiexec -n 2 -hosts

Any thoughts?
