Performance Evaluation of OpenMP Applications with Nested Parallelism
[chapter]
2000
Lecture Notes in Computer Science
Many existing OpenMP systems do not suciently implement nested parallelism. This is supposedly because nested parallelism is believed to require a signicant implementation eort, incur a large overhead, or lack applications. This paper demonstrates Omni/ST, a simple and ecient implementation of OpenMP nested parallelism using StackThreads/MP, which i s a ne-grain thread library. Thanks to StackThreads/MP, OpenMP parallel constructs are simply mapped onto thread creation primitives of
