Evaluating Zoltan for Static Load Balancing on BlueGene Architectures

[摘要] The purpose of this TechBase was to evaluate the Zoltan load-balancing library from Sandia National Laboratories as a possible replacement for ParMetis, which had been the load balancer of choice for nearly a decade but does not scale to the full 64,000 processors of BlueGene/L. This evaluation was successful in producing a clear result, but the result was unfortunately negative. Although Zoltan presents a collection load-balancing algorithms, none were able to meet or exceed the combined scalability and quality of ParMetis on representative datasets.
