Junchao,
I won't be feasible to share the code but I will run a similar test
as you have done (large problem); I will
try with both MPICH and OpenMPI. I also agree that deltas are not ideal
as there they do not account for latency in the freeing of memory
etc. But I will note when we have th

have to instrument the code outside of KSPSolve(). In
