MPAS developers,

The ocean model is now in a state where we are testing high resolution 
simulations.  It appears that we are limited by the lack of parallel 
i/o.  I think I've seen a few commits on this.  Micheal, are there plans 
for parallel i/o for the mpas framework?

When I run with our 15km ocean mesh, which has
         nCells = 1848103 ;
         nEdges = 5578724 ;
I get an  'insufficient virtual memory' error at the time of the first 
output write.

Thanks,
Mark
