Thread Scheduling for Multi-Core Platforms

Mohan Rajagopalan, Brian T. Lewis, Todd A. Anderson
2007 USENIX Workshop on Hot Topics in Operating Systems  
We introduce in this paper a novel scheduling framework for multi-core processors that strikes a balance between control over the system and the level of abstraction.  ...  Our framework uses high-level information supplied by the user to guide thread scheduling and also, where necessary, gives the programmer fine control over thread placement.  ...  Acknowledgments We want to thank Jim Stichnoth, Neal Glew, and Youfeng Wu for their help in preparing this paper. We also thank the anonymous referees for their helpful feedback and suggestions.  ...
