This paper describes an efficient implementation of one-sided communication on top of the GM low-level message-passing library for clusters with Myrinet. This approach is compatible with shared memory, exploits pipelining, nonblocking communication, and overlapping memory registration with memory copy to maximize the transfer rate. The paper addresses critical design issues faced on the commodity clusters and then describes possible solutions for matching the low-level network protocol with user-level interfaces. The performance implications of the design decisions are presented and discussed in context of a standalone communication benchmark as well as two applications. Finally, the paper offers some indications on what additional features would be desirable in a communication library like GM to better support one-sided communication.
