Detailed Description

Simple default static load balancing strategy suitable for many cases.

This load balancing strategy assigns one collector rank for each model index, one worker per group and proceeds to evenly split groups across indices. It clearly makes no further assumptions on the model, and would best be used together with dynamic load balancing during runtime.
