Network-Friendly One-Sided Communication through Multinode Cooperation on Petascale Cray XT5 Systems
2011
2011 11th IEEE/ACM International Symposium on Cluster, Cloud and Grid Computing
One-sided communication is important to enable asynchronous communication and data movement for Global Address Space (GAS) programming models. Such communication is typically realized through direct messages between initiator and target processes. For petascale systems with 10,000s of nodes and 100,000s of cores, these direct messages require dedicated communication buffers and/or channels, which can lead to significant scalability challenges for GAS programming models. In this paper, we
