The Ull Multiobjective Framework provides the necessary tools to perform dynamic load balancing in parallel iterative problems, mainly for heterogeneous systems. It is designed to simplify complex metric gathering and algorithms with a simple interface that require few lines of code.
There are three implemented strategies to perform the dynamic load balancing:
- Calibrate
- Energy Heuristic
- Time Heuristic
Both the Calibrate and Time Heuristic perform load balance based on the differences in computational power. They differenciate from each other in how they generate new distributions. The Energy heuristic perform operations that are similar to the Time Heuristic, focused mainly in reducing energy consumption.
More details can be found in the associated publications.

Required:
- MPI, required for gathering metrics from the different parallel processes.
Optional:
- EML, for Energy measurement support
