Group Different MPI Size or Nodes for In-Situ Analysis #61
Description
Group Different MPI Size or Nodes for In-Situ Analysis
Currently, using MPI size N in simulations will make yt in-situ analysis run with MPI size N.
We want to make it more flexible by giving user freedom to group what MPI ranks should run simulation and what ranks for in-situ analysis.
Feature
- Use different number of MPI processes for simulations and in-situ analysis.
