Abstract. A fault tolerant parallel virtual file system is designed and implemented to provide high I/O performance and high reliability. A queuing model is used to analyze in deta...
We are working on a system for the optimised access and replication of data on a Data Grid. Our approach is based on the use of an economic model that includes the actors and the ...

As computing breaches petascale limits both in processor performance and storage capacity, the only way that current and future gains in performance can be achieved is by increasi...
In this paper, we propose a modified parallel virtual file system that provides snapshot functionality. Because typical file systems are exposed to various failures, taking a s...
