Dear readers, when you are hunting the new book collection to read this day, using mpi portable parallel programming with the message passing interface can be your referred book. Yeah, even many books are offered, this book can steal the reader heart so much. The content and theme of this book really will touch your heart. You can find more and more(More)
MPI (Message Passing Interface) is a specification for a standard library for message passing that was defined by the MPI Forum, a broadly based group of parallel computer vendors, library writers, and applications specialists. Multiple implementations of MPI have been developed. In this paper, we describe MPICH, unique among existing implementations in its(More)
Parallel numerical software based on the message-passing model is enormously complicated. This paper introduces a set of techniques to manage the complexity, while maintaining high eeciency and ease of use. The PETSc 2.0 package uses object-oriented programming to conceal the details of the message passing, without concealing the parallelism, in a(More)
We discuss the issues involved in implementing MPI-IO portably on multiple machines and file systems and also achieving high performance. One way to implement MPI-IO portably is to implement it on top of the basic Unix I/O functions (open, lseek, read, write, and close), which are themselves portable. We argue that this approach has limitations in both(More)

We describe our work on improving the performance of collective communication operations in MPICH for clusters connected by switched networks. For each collective operation, we use multiple algorithms depending on the message size, with the goal of minimizing latency for short messages and minimizing bandwidth use for long messages. Although we have(More)
This talk will describe MPICH2, an all-new implementation of MPI designed to support both MPI-1 and MPI-2 and to enable further research into MPI implementation technology. To achieve high-performance and scalability and to encourage experimentation, the design of MPICH2 is strongly modular. For example, the MPI topology routines can easily be replaced by(More)
This paper describes current activities of the MPI-2 Forum. The MPI-2 Forum is a group of parallel computer vendors, library writers, and application specialists working together to de ne a set of extensions to MPI (Message Passing Interface). MPI was de ned by the same process and now has many implementations, both vendor-proprietary and publicly(More)
