Title:
A Case Study for a New Invasive Extension of Intel’s Threading Building Blocks 
Abstract:
We study codes deploying multiple MPI ranks to one node where each rank is parallelised with TBB. A static assignment of cores to ranks here is disadvantageous if the load is not perfectly balanced, the runtime is subject to fluctuations or one MPI rank runs through phases with low concurrency. We propose an extension to TBB where developers manually annotate which code parts could exploit further cores. The cores are then dynamically associated with ranks. Our approach is decentralised, lightwe...    »
