[mvapich-discuss] Failed to dealloc pd (Device or resource busy) message, what does it mean?

[Deva]

Hi Ben

This message indicates some IB resource (QP, CQ ..etc) is not freed
properly in MPI_Finalize().  As you indicated, this do not affect normal
execution of the code.
What run time options you had for this run?
