Parallel netCDF: A Scientific High-Performance I/O Interface
Jianwei Li, Wei-keng Liao, Alok Choudhary +4
Dataset storage, exchange, and access play a critical role in scientific applications. For such purposes netCDF serves as a portable and efficient file format and programming inter…
Noncontiguous I/O through PVFS
Avery Ching, Alok Choudhary, Wei-keng Liao +2
With the tremendous advances in processor and memory technology, I/O has risen to become the bottleneck in high-performance computing for many applications. The development of para…
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…
