2005 Proceedings IEEE International Conference on Cluster Computing  
In addition to 10GigE's advantage with respect to compatibility to wide-area network infrastructures, e.g., in support of grids, our results show that 10GigE also delivers performance that is comparable  ...  to traditional high-speed network technologies such as IBA and Myrinet in a system-area network environment to support clusters and that 10GigE is particularly wellsuited for sockets-based applications  ...  PVFS supports a set of feature-rich interfaces, including support for both contiguous and noncontiguous accesses to both memory and files.  ...

P. Balaji, Wu-chun Feng, D.K. Panda
2006 IEEE Micro  
PVFS also supports a set of feature-rich interfaces, including support for both contiguous and noncontiguous accesses to both memory and files.  ...  This is likely due to the MPI-Tile-I/O benchmark's noncontiguous data-access pattern, which adds significant overhead.  ...

Demotion-based exclusive caching through demote buffering

Jiesheng Wu, Pete Wyckoff, Dhabaleswar K. Panda
2003 Proceedings of the international workshop on Storage network architecture and parallel I/Os - SNAPI '03  
In this paper, we propose a DEMOTE buffering mechanism over storage networks to reduce the visible costs of DEMOTE operations and provides more flexibility for optimizations.  ...  Multi-level buffer cache architecture has been widely deployed in today's multiple-tier computing environments. However, caches in different levels are inclusive.  ...  This work was supported in part by Sandia National Laboratory's contract #30505, Department of Energy's Grant #DE-FC02-01ER25506, and National Science Foundation's grants #EIA-9986052 and #CCR-0204429.  ...
