....restricted subset of the functionality of MPI Comm join in MPI 2.0 [12] It is impossible to merge the bridge s inter communicator into a global intra communicator over all processes. Therefore, one can not execute existing MPI applications with PVMPI on a cluster of parallel systems. In the PLUS [3] project at PC 2 at the University of Paderborn a bridge has been developed too. With this bridge MPI and PVM worlds can be combined. Inefficient TCP implementations of some vendors have been substituted by an own protocol based on UDP. It is optimized for wide area networks. As in PACX MPI the ....

Some environments [5, 3] have been developed to integrate interoperability. In this paper, we describe our multi cluster approach based on PM 2 . PM 2 [11] is a parallel programming environment which is not based upon message passing procedures: its programming paradigm is to express a parallel program as a set of ....

Some of the issues concerningmetacomputer access and job submission, scheduling, and load balancing are discussed in the next sections. Within the MOL partner project, the PLUS lightweight communication interface [2] addresses inter operability between heterogeneous platforms and different message passing layers. PLUS encapsulates message passing specific communication primitives (e.g. MPI Send, pvm send) and enables inter operability between MPI and PVM applications. 3.1 Resource Management in the Polder ....

....and has partially replaced PVM on MPPs. The aim was therefore to use MPI also in metacomputing. However, there is no implementation of MPI available today that allows to integrate several MPPs for one single application. Some tools that aim to support metacomputing try to bridge that gap [4, 5, 6] but require the user to change his application. MPICH [7] that aims to support heterogeneous clusters is currently not supporting Cray T3E. The goal of PACX was to not change the code and supply the user with a standard MPI environment. So applications could run without change on more than one ....
