Optimizing Noncontiguous Accesses in MPI-IO
Rajeev Thakur, William Gropp, Ewing Lusk
The I/O access patterns of many parallel applications consist of accesses to a large number of small, noncontiguous pieces of data. If an application's I/O needs are met by making…
A Multilevel Approach to Topology-Aware Collective Operations in Computational Grids
N. T. Karonis, B. de Supinski, I. Foster +2
The efficient implementation of collective communiction operations has received much attention. Initial efforts produced "optimal" trees based on network communication models that…
Scalable Unix Commands for Parallel Processors: A High-Performance Implementation
E. Ong, E. Lusk, W. Gropp
We describe a family of MPI applications we call the Parallel Unix Commands. These commands are natural parallel versions of common Unix user commands such as ls, ps, and find, tog…
Components and Interfaces of a Process Management System for Parallel Programs
Ralph Butler, William Gropp, Ewing Lusk
Parallel jobs are different from sequential jobs and require a different type of process management. We present here a process management system for parallel programs such as those…
