We are planning on changing the way load balancing is implemented in Charm++. The main reasons for these changes are to allow for more sophisticated load balancing scenarios such as node level load balancing, improved performance, and cleanup of years of accumulated cruft.

Part of this effort involves removing many of the current load balancers, instead focusing on a smaller set of well maintained and generally applicable load balancers.

Please respond if you think the list below should be expanded to include other load balancers, as well as with other relevant suggestions on the new forum topic: https://charm.discourse.group/t/cleanup-the-set-of-load-balancing-strategies/34

We intend to keep at least the following set:

DistributedLB

DummyLB

GreedyLB

GreedyRefineLB

MetisLB/ScotchLB/ZoltanLB

RandomLB

RefineLB (and TempAwareRefineLB variant)

RotateLB
