among different discretization approaches, finite difference method (fdm) is widely used for acoustic and elastic full-wave form modeling. an inevitable deficit of the technique, however, is its sever requirement to computational resources. a promising solution is parallelization, where the problem is broken into several segments, and the calculations are distributed over different processors. ...

The MPI Forum This paper presents an overview of mpi, a proposed standard message passing interface for MIMD distributed memory concurrent computers. The design of mpi has been a collective eeort involving researchers in the United States and Europe from many organizations and institutions. mpi includes point-to-point and collective communication routines, as well as support for process groups,...

The Message Passing Interface (MPI) is designed as an architecture independent interface for parallel programming in the shared-nothing, message passing paradigm. We briefly summarize basic requirements to a high-quality implementation of MPI for efficient programming of SMP clusters and related architectures, and discuss possible, mild extensions of the topology functionality of MPI, which, wh...

The Message{Passing Interface (MPI) provides support for portable parallel programs, but often proves too complex to be convenient. In this paper we propose a higher{level Programmer's Message{ Passing Interface (PMPI) to the standard MPI libraries that is better suited to the needs of application programmers. PMPI largely hides the binding of message{passing routines to the programming languag...

This article describes the ongoing work of real-time message passing interface (MPI) standardization. Real-time MPI (MPI/RT) provides a consistent set of extensions and, in some cases, restrictions to the high-performance computing Message Passing Interface Standard, emphasizing changes that enable and support real-time communication and are supportable on embedded and other real-time systems.

The Message Passing Interface provides an interface for onesided communication as part of the MPI-2 standard. The semantics specified by MPI-2 allow for a number of different implementation avenues, each with different performance characteristics. Within the context of Open MPI, a freely available high performance MPI implementation, we analyze a number of implementation possibilities, includin...

Message-passing is a well known approach for parallelizing programs. The widely used standard MPI (Message passing interface) also defines C++ bindings. Nevertheless, there is a lack of integration of object-oriented concepts. In this paper, we describe our design of TPO++1, an object-oriented message-passing library written in C++ on top of MPI. Its key features are easy transmission of object...

The goal of the Message Passing Interface (MPI) is to develop a widely used standard for writing message-passing programs. The interface has become an important and increasingly popular and portable message passing system that makes the development of practical and cost-effective large-scale parallel applications possible. EPCC has been developing an MPI Simulator to be used by the Training and...

In this paper, we apply two different parallel programming model, the message passing model using Message Passing Interface (MPI) and the multithreaded model using Pthreads, to protein sequence homologous search. The protein sequence homologous search uses Hirschberg algorithm for the pair-wise sequence alignment. The performance of the homologous search using the MPI-Pthread is compared to the...
