Why Are Pvm and Mpi so Diierent?

چکیده
PVM and MPI are often compared. These comparisons usually start with the unspoken assumption that PVM and MPI represent diierent solutions to the same problem. In this paper we show that, in fact, the two systems often are solving diierent problems. In cases where the problems do match but the solutions chosen by PVM and MPI are diierent, we explain the reasons for the diierences. Usually such diier-ences can be traced to explicit diierences in the goals of the two systems, their origins, or the relationship between their speciications and their implementations.

Pvm and Mpi Are Completely Diierent
PVM and MPI are often compared. These comparisons usually start with the un-spoken assumption that PVM and MPI represent diierent solutions to the same problem. In this paper we show that, in fact, the two systems often are solving diierent problems. In cases where the problems do match but the solutions chosen by PVM and MPI are diierent, we explain the reasons for the diierences. Usually such...

متن کاملComparative analysis of PVM and MPI for the development of physical applications on parallel clusters∗
PVM and MPI, two systems for programming clusters, are often compared. Each system has its unique strengths and this will remain so into the foreseeable future. This paper compares PVM and MPI features, pointing out the situations where one may be favored over the other; it explains the differences between these systems and the reasons for such differences. PVM – Parallel Virtual Machine; MPI –...
متن کاملCommunication Performance of Java based Parallel
Message passing libraries such as Parallel Virtual Machine (PVM) and Message Passing Interface (MPI) provide a common Application Programming Interface (API) to implement parallel programs across multiple computers. Such libraries provide a means to program a collection of normally independent computers to work cooperatively on a single computation. However, for programs written in C and Fortra...
متن کاملTowards Portable Message Passing in Java: Binding MPI
In this paper we present a way of successfully tackling the diiculties of binding MPI to Java with a view to ensuring portability. We have created a tool for automatically binding existing native C libraries to Java, and have applied the Java{to{C Interface generating tool (JCI) to bind MPI to Java. The approach of automatic binding by JCI ensures both portability across diierent platforms and ...
