Comparison of PVM and MPI on SGImultiprocessors in a High
نویسندگان
چکیده
In this work the well known wavelet/subband decomposition algorithm (3-D case) widely used in picture and video coding is parallelized using PVM and MPI as well as with data parallel language extensions. The approaches try to take advantage of the possibilities the respective programming interfaces ooer. Experimental results are conducted on an SGI POWERChallenge GR and an SGI Origin 2000. These results show a good comparison of the programming approaches as well as the programming interfaces in a practical environment.

On-Line Monitoring Support in PVM and MPI
PVM and MPI have often been compared regarding their functionality and performance from the users' point of view. In this paper , however, we will present some comparison from a tool developer's point of view. We will show how a supporting infrastructure { the OMIS compliant monitoring system OCM { can be implemented for both PVM and MPI. Thus, we will put light onto those features of PVM and M...

This paper compares PVM and MPI features pointing out the situ ations where one may be favored over the other Application developers can determine where their application most likely will run and if it re quires particular features supplied by only one or the other of the APIs MPI is expected to be faster within a large multiprocessor It has many more point to point and collective communication...
متن کاملPVM and MPI Communication Operations on the IBM SP2: Modeling and Comparison
Most current message passing programs use the portable communication libraries PVM and MPI to realize communication. In this paper, we investigate the performance of single transfer operations and several collective communication operations, like broadcast or gather operations, using the portable communication libraries PVM and MPI on the IBM SP2. Our investigations include timings of different...
متن کاملA Performance Evaluation of Rpc, Java Rmi, Mpi and Pvm
This paper presents performance comparison of Remote Procedure Calls (RPC), Java Remote Machine Invocation (RMI), Message Passing Interface (MPI) and Parallel Virtual Machine (PVM). The Bandwidth, latency and parallel processing time are measured using standard benchmarks. The results show that the MPI performance is much closer to RPC performance.
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 –...
