[mvapich-discuss] Dual port IB, usage

Hi Troy,

Thanks for your mail.

MVAPICH supports this configuration. MVAPICH allows a process to "bind"
to a particular port. The other available ports will not be used by this
MPI application. Hence, other applications can "bind" to free port(s)
without any traffic interference.

Hope this helps.

Thanks,
