[mvapich-discuss] mvapich 1.0.1 Got error polling CQ

[Dhabaleswar Panda]

This error indicates that when a process is able to poll Completion Queue
(CQ) of InfiniBand ntwork, it is getting an error.

On your IB set-up, are you able to carry out IB native-level (verbs-level,
not MPI-level) tests across the nodes. Please make sure that the IB set-up
is correct. Then you can carry out MPI-level tests.
