This paper presents the design of an MPI (Message Passing Interface)-based parallel file system, MPFS. MPI-IO is an extension of MPI which supports flexible logical file partition and physical file organization as well as a rich set of file access functions. MPFS enables users to specify both logical file partitions among user processes and physical file data layouts across data servers. The pr...

The goal of this work is to overcome the learning barriers faced when first using parallelism. Currently, in order to parallelize a system such as GAP, one must embed a message passing library such as MPI, with many routines and many parameters. GAP/MPI provides a simple, task-oriented interface sitting above the MPI library. The system presents the end-user with a single SPMD (single program, ...

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...

The Message Passing Interface (MPI) is the de facto standard message-passing infrastructure for developing parallel applications. Two decades after the first version of the library specification, MPI-based applications are nowadays routinely deployed on super and cluster computers. These applications, written in C or Fortran, exhibit intricate message passing behaviours, making it hard to stati...

This paper is concerned with parallel FFT and Quick-Merge Sort. They are implemented on computers interconnected by VMIC 5579 reflective memory and a cluster of workstations (PCs) interconnected via Fast Ethernet. Message passing interface (MPI) parallel library is used for communication in a cluster of workstations. An improved parallel FFT is also presented to decrease an execution time in th...

Theoretical models are difficult to apply for the analysis of practical message passing systems used today. We propose a model which can be used for such an analysis. Our framework for message passing is in many ways similar to the framework for transactional database systems. The abstract message passing system is defined in our framework independently of hardware, operating system and means o...

1. This work was supported through NASA contract NAS 2-12961. Abstract Multidisciplinary and multi-zonal applications are an important class of applications in the area of Computational Aerosciences. In these codes, two or more distinct parallel programs or copies of a single program are utilized to model a single problem. To support such applications, it is common to use a programming model wh...

Since version 2 of the Message Passing Interface (MPI) the MPI job has the ability to start new processes dynamically at runtime. The MPI implementation has to care for the creation of new communication channels in those situations. This work desribes the implications of dynamic process creation on an communication module for the Scalable Coherent Interface (SCI). The module is developed for th...

The major contribution of this paper is the application of modern analysis techniques to the important Message Passing Interface standard, work done in order to obtain information useful in designing both application programmer interfaces for objectoriented languages, and message passing systems. Recognition of \Design Patterns" within MPI is an important discernment of this work. A further con...
