[lazy, distributed] Unnecessary communication/computation

[kaushikcfd]

One of the DAG partitions for the CNS DG operator looks like:

Many of the data being communicated/computed are data-wrappers. And both computation and communication of such values at each iteration should not happen, IMO.

Thanks!

My bad, these aren't communicated only re-evaluated at each iteration.

Thanks for looking at the partitioned DAGs carefully! I do suspect there's some stupidity in there somewhere.
