[mvapich-discuss] MVAPICH2 spawn problem

[wei huang]

Hi,

Thanks for using mvapich2. Unfortunately, the spawn support is not there
yet with the native IB stack. We are taking a look at this issue and plan
to support this in our future releases soon. TCP/IP stack using IPoIB
should always work for you.

Thanks.

Regards,
Wei Huang
