Improve PEBBL load balancing

Reported by: jeckstei Owned by: jeckstei
Priority: normal Milestone: Acro 2.1
Component: PEBBL Version:
Keywords: Cc:
Subcomponent: Source Code

Description

The load logging tool reveals that PEBBL load balancing with knapsack is poor -- processors are getting starved for work. This may also extend to the docking app. Try to improve load distribution (possibly by explicitly keeping processors within a certain fraction of the total load).

The basic problem was fixed some time ago. Improvements to the handling over overlapped worker-hubs will be committed soon. It isn't perfect when the subproblems are super-easy, but it's much, much better.
