A Flexible Multiagent Parallel File System for Clusters [chapter]

María S. Perez, Jesús Carretero, Félix García, José M. Peña, Víctor Robles
2003 Lecture Notes in Computer Science  
In this sense, parallel I/O is becoming one of the major topics in the area of high-performance systems.  ...  Many of these applications require access to huge data repositories and other I/O sources, being the I/O phase a bottleneck in the computing systems, due to its poor performance.  ...  The usage of hints related to different aspects of data distribution and access patterns allows parallel file systems to increase the performance of these operations.  ...
