Happy to discuss more about this.

Why comment out the uw.mpi.call_pattern part? This was useful for dealing with sequential or parallel hdf5 implementations on various HPCs.

From tests I've done it hasn't made a difference to the order of the array. If anything needed to be sequential it would be the gathering of the data on the root processor not the creation of the array on each processor. I'm not sure how Gatherv gathers the data but from those tests thee array is in the same order each time.
