[mvapich-discuss] Erros with MVAPICH2-0.9.3

[Amit H Kumar]

Hi Lei Chai,

Thank you for your feedback.

The -env VIADEV_ENABLE_AFFINITY 0 fixed the Affinity errors. But I still
get those VIP errors. Is there is any immediate fix for that.

Does it mean that the VAPI library setup needs to be re-visited on our
system.
Or this is something which we can ignore? Also jobs resulting in these
errors never get terminated.

Thank you,
Amit
