Scalable Unix Commands for Parallel Processors: A High-Performance Implementation
نویسندگان
چکیده
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, together with a few similar commands particular to the parallel environment.We describe the design and implementation of these programs and present some performance results on a 256-node Linux cluster. The Parallel Unix Commands are open source and freely available.

متن کاملI/O for TFLOPS Supercomputers
Scalable parallel computers with TFLOPS (Trillion FLoating Point Operations Per Second) performance levels are now under construction. While we believe TFLOPS processor technology is sound, we believe the software and I/O systems surrounding them need improvement. This paper describes our view of a proper system that we built for the nCUBE parallel computer and which is now commercially availab...
متن کاملDeveloping a Secure Grid Computing Environment Shell Engine: Containers and Services
We describe the design and features of our Grid Computing Environments Shell system, or GCEShell. We view computing Grids as providing essentially a globally scalable distributed operating system that exposes low level programming APIs. From these system-level commands we may build a higher level library of more user-friendly shell commands, which may in turn be programmed through scripts. The ...
متن کاملDesign of Digital's Parallel Software Environment
designed to support the development and execution of scalable parallel applications on clusters (farms) of distributedand shared-memory Alpha processors running the Digital UNIX operating system. PSE version 1.0 supports the High Performance Fortran (HPF) language; it also supplies generic facilities required by other parallel languages and systems. PSE provides tools to define a cluster of pro...
متن کاملParallel Spatial Pyramid Match Kernel Algorithm for Object Recognition using a Cluster of Computers
This paper parallelizes the spatial pyramid match kernel (SPK) implementation. SPK is one of the most usable kernel methods, along with support vector machine classifier, with high accuracy in object recognition. MATLAB parallel computing toolbox has been used to parallelize SPK. In this implementation, MATLAB Message Passing Interface (MPI) functions and features included in the toolbox help u...
