MESH: MEssaging and scheduling for fine-grain parallel processing on commodity platforms

摘要

MESH is a tight integration of a user-level thread scheduler and a zero-copy messaging system that enables effiicent fine-grain parallel processing on commodity platforms with efficient support for fault-tolerance. We presnt the efficient support for fault-tolerance. We present the techniques used to deliver most of the performance of the underlying communication hardware to a multi-threaded application level, while introducing little CPU overhead. This is demonstrated by a performanc eanalysis of a MESH implementation requiring only off-the-shelf products: PCs,running the Linux operating systme, equipped with Fast and Gigabit Ethernet network interface cards.
