Optimization Strategies for Data Distribution Schemes in a Parallel File System

  • Parallel systems leverage parallel file systems to efficiently perform I/O to shared files. These parallel file systems utilize different client-server communication and file data distribution strategies to optimize the access to data stored in the file system. In many parallel file systems, clients access data that is striped across multiple I/O devices or servers. Striping, however, results in poor access performance if the application generates a different stride pattern. This work analyzes optimization approaches of different parallel file systems and proposes new strategies for the mapping of clients to servers and the distribution of file data with special respect to strided data access. We evaluate the results of a specific approach in a parallel file system for main memory.
