MPI_T: multi-dimensional pvars

[mahermanns]

Problem

With multiple network devices present on a node, MPI_T could provide individual stats to each device in a multi-value pvar, but it is unclear how the array slots relate to the devices on the node.

Proposed solution

Enable the expression of a connection between pvars and enums.

Implementation

Implementations will have to add the proposed interface.
