Hints to improve automatic load balancing with LeWI for hybrid applications
2014
Journal of Parallel and Distributed Computing
Preserved Fulltext
The DLB (Dynamic Load Balancing) library and LeWI (LEnd When Idle) algorithm provide a runtime solution to deal with the load imbalance of parallel applications independently of the source of imbalance ...
This work is a deep analysis of the sources of efficiency loss correlated with application characteristics, parallelization schemes and programming models. ...

We validate our approach with different benchmark suites for simulations with artificial workload as well as applications based on dynamically adaptive shallow water simulations, and investigate concurrently ...
Achieving high scalability with dynamically adaptive algorithms in high-performance computing (HPC) is a non-trivial task. ...
This sets up demands to the application developer either to extend interfaces of meshing tools supporting dynamical remeshing and load balancing or to manually implement the load balancing and data migration ...
