Using Semantics-aware Composition and Weaving for Multi-variant Progressive Parallelization

Autor: Jochen Frhlich, Uwe Amann, Immo Huismann, Johannes Mey, Sven Karol, Jrg Stiller

Publikováno v: ICCS

When writing parallel software for high performance computing, a common practice is to start from a sequential variant of a program that is consecutively enriched with parallelization directives. This process – progressive parallelization – has t

This paper investigates static load balancing models for CPU-GPU coupling from a computational fluid dynamics perspective. While able to generate a benefit, traditional load balancing models are found to be too inaccurate to predict the runtime of a
