TiNy threads on BlueGene/P: Exploring many-core parallelisms beyond The traditional OS

Operating Systems (OSs) have been considered as a cornerstone of the modern computer system, and the conventional operating system model targets computers designed around the sequential execution model. However, with the rapid progress of the multi-core/manycore technologies, we argue that OSes must be adapted to the underlying hardware platform to fully exploit parallelism. To illustrate this, our paper reports a study on how to perform such an adaptation for the IBM BlueGene/P multi-core system.
