BULLY

WMPI Message Passing Interface for Win32 clusters, (Win32). Its internal architecture and user interface, and some performance test results (for release v1.1), that evaluates how much of the total underlying system capacity for communication is delivered to the MPI based parallel applications, are presented. WMPI is based on MPICH, a portable imple

Developing message-passing applications on MPICH under ensemble,ecutables having open, scalable interfaces and by scripts specifying process communication graphs, annotated with application execution information. An MPICH procgroup file is generated from scripts and executed my mpirun.

SPASM

Evaluating and modeling communication overhead of MPI primitives on the Meiko CS-2,on the size of messages exchanged and the number of involved processors. Finally, the MPI performance results on the CS-2 are compared with the performance of the Meiko Elan Widget library and the IBM SP2.

MUT

Improving the PVM daemon network performance by direct network access,/IP. The DNA includes a non-polling receive mechanism, an efficient mutual exclusion mechanism and a shared buffer management scheme, thus enabling operation in a time sharing environment. The paper describes the DNA and its integration in the PVM daemon, and presents performance results, which amount to a latency reduction of 18% for PVM tasks.

SKaMPI: A detailed, accurate MPI benchmark,s. Postprocessors support graphical presentation and comparisons of different sets of results which are collected in a public web-site. We describe the . design and implementation and illustrate its main aspects with actual measurements.

Harness: The next generation beyond PVM, extend a virtual machine‘s features to more closely match the needs of their application and to optimize for the underlying computer resources. This paper will describe the architecture and core services of this new virtual machine paradigm, our progress on this project, and our experiences with early prototypes of Harness.
