Network-Friendly One-Sided Communication through Multinode Cooperation on Petascale Cray XT5 Systems

Xinyu Que, Weikuan Yu, Vinod Tipparaju, Jeffrey S. Vetter, Bin Wang
2011 2011 11th IEEE/ACM International Symposium on Cluster, Cloud and Grid Computing  
In this paper, we describe a network-friendly communication model, multinode cooperation, to enable indirect one-sided communication.  ...  One-sided communication is important to enable asynchronous communication and data movement for Global Address Space (GAS) programming models.  ...  The servers in a multinode group then cooperate and handle one-sided requests from processes outside the group.  ...

An experimental comparison of remote procedure call and group communication

M. Frans Kaashoek, Andrew S. Tanenbaum, Kees Verstoep
1992 Proceedings of the 5th workshop on ACM SIGOPS European workshop Models and paradigms for distributed systems structuring - EW 5  
This paper suggests that a distributed system should support two communication paradigms: Remote Procedure Call (RPC) and group commumcation.  ...  We demonstrate that group communication is an important paradigm by showing that a fault-tolerant directory service is much easier to implement with groups than with RPC and is also more efficient.  ...  Acknowledgements Robbert van Renesse and Mark Wood provided comments on an eaa'lier draft of this paper, which improved its content and presentation substantially.  ...

Cooperative server clustering for a scalable GAS model on petascale cray XT5 systems

Weikuan Yu, Xinyu Que, Vinod Tipparaju, Richard L. Graham, Jeffrey S. Vetter
2010 Computer Science - Research and Development  
In cooperative server clustering, ARMCI servers are organized into clusters, and cooperatively process incoming communication requests among them.  ...  Global Address Space (GAS) programming models are attractive because they retain the easy-to-use addressing model that is the characteristic of shared-memory style load and store operations.  ...  to study the applicability of cooperative server clustering to GA and ARMCI on other petascale platforms such as Blue-Gene /P.  ...
