The message passing interface (MPI) is a standardized means of exchanging messages between multiple computers running a parallel program across distributed memory. In parallel computing, multiple computers – or even multiple processor cores within the same computer – are called nodes. Each node in t...

The growing number of different message-passing interfaces make it difficult to port an application program from one parallel computer to another. This is a major problem in parallel computing.

Message-passing has become the most popular programming-paradigm to overcome this problem. One hardware-approach that is driving the development of parallel systems and parallel software is clusters of workstations. Being available nearly everywhere, they offer the opportunity to get parallel performance...
Methods, apparatus, and products are disclosed for performance testing of message passing operations in a parallel computer, the parallel computer comprising a plurality of compute nodes organized into at least one operational group, that include: establishing, on a compute node of the operational grou...
The SCMP (Single-Chip Message-Passing) parallel computer system is one such architecture. The SCMP system includes up to 64 processors on a single chip, connected in a 2-D mesh with nearest neighbor connections. Memory is included on-chip with the processors and the architecture includes ...
In this approach, initial population has been divided between the processors chosen at run time. Numerical values obtained using above approach are at last compared for standard test functions. 展开 关键词: asynchronous PSO parallel computing message passing interfaces ...
An increasing number of commodity clusters are connected to each other by public networks, which have become a potential threat to security sensitive parallel applications running on the clusters. To address this security issue, we developed a Message Passing Interface (MPI) implementation to preserve...
A parallel message-passing implementation of a molecular dynamics (MD) program that is useful for bio(macro)molecules in aqueous environment is described. The software has been developed for a custom-designed 32-processor ring GROMACS (GROningen MAchine for Chemical Simulation) with communication to ...
