ML: Issue 3565

James Willenbring requested to merge rhoope:ml_issue3565 into develop

Created by: rhoope

Fix to allow user-supplied MPI_Comm in the C-API.

@trilinos/ Request review by @csiefer2

Description

The C-API for MLCreate was hard-coded to use MPI_COMM_WORLD which breaks MPMD uses.

Motivation and Context

Closes Issue #3565 (closed)

How Has This Been Tested?

I ran the application code in MPMD code to verify the previous error is no longer encountered.
