:rocket: Parallel/dynamic load balancing #616

Closed kks32 closed 4 years ago

kks32 commented 4 years ago

Describe the PR Dynamic load balancing with graph updates at a fixed frequency. This improves performance with 4 MPI tasks by 1.6x compared to the case of no load balancing.

Additional context Graph class is split to multiple functions to construct graph at different stages to calculate # of particles/cell and repartition graph
