Improving the Performance of the POSIX I/O Interface to PVFS

The ever-increasing gap in performance between CPU/memory technologies and the I/O subsystem (disks, I/O buses) in modern workstations has exacerbated the I/O bottlenecks inherent in applications that access large disk resident data sets. A simultaneous development in recent times has seen the maturity of Linux-based offthe-shelf clusters of PCs for low-cost, high-performance computing solution...

I/O in Parallel Applications: the Weakest Link

Parallel computers are increasingly being used to run large-scale applications that also have huge I/O requirements. However, many applications obtain poor I/O performance on modern parallel machines. This special issue of IJSA contains papers that describe the I/O requirements and the techniques used to perform I/O in real parallel applications. We rst explain how the I/O application program i...

ChemIo: High Performance Parallel I/o for Computational Chemistry Applications

Recent developments in I/O systems on scalable parallel computers have sparked renewed interest in out-of-core methods for computational chemistry. These methods can improve execution time significantly relative to “direct” methods, which perform many redundant computations. However, the widespread use of such out-of-core methods requires efficient and portable implementations of often complex ...

A Study of I/O Techniques for Parallel Visualization

This paper presents two parallel I/O methods for the visualization of time-varying volume data in a high-performance computing environment. We discuss the interplay between the parallel renderer, I/O strategy, and file system, and show the results of our study on the performance of the I/O strategies with and without MPI parallel I/O support. The targeted application is earthquake modeling usin...

Speeding up Automatic Parallel I/o Performance Optimization in Panda

The large number of system components and their complex interactions in a parallel I/O system, together with dynamically changing I/O patterns in scientiic applications, impose a great challenge in selecting optimal I/O plans for an anticipated I/O workload in a target execution environment. Previous research has shown that a model-based approach that uses a performance model of the parallel I/...

Heuristics for Scheduling I/O Operations

The I/O bottleneck in parallel computer systems has recently begun receiving increasing interest. Most attention has focused on improving the performance of I/O devices using fairly low-level parallelism in techniques such as disk striping and interleaving. Widely applicable solutions, however, will require an integrated approach which addresses the problem at multiple system levels, including ...
