The message passing model is now widely used for parallel computing, but is still difficult to use with some applications. The explicit data distribution or the explicit dynamic creation of parallel tasks can require a complex algorithm. In this paper, in order to avoid explicit data distribution...
Message passing is the current standard programming model for multi-compute node parallel computing systems. The idea of message passing has existed for many years. The idea of message-based networks formed the basis for what we now know as the Internet. The Internet and other wide area networks...

While there are some programming model to express parallelism, thread programming model has become a standard to support these system such as OpenMP, and POSIX threads. MPI (Message Passing Interface) which remains the dominant model used in high-performance computing today faces this challenge. ...

This paper presents F-MPJ (Fast MPJ), a scalable and efficient Message-Passing in Java (MPJ) communication middleware for parallel computing. The increasing interest in Java as the programming language of the multi-core era demands scalable performance on hybrid architectures (with both shared and...
MPI has helped in networking and parallel computing on an industrial and global scale, and helped improve the working of large-scale parallel computer applications. Basic design goals of using MPI include portability, flexibility and efficiency. Message Passing Interface is not an IEEE or IOS ...
The relationship between client-server distributed computing and message-passing parallel processing is explored in this work through an experimental RPC framework for the PVM system. The project investigates the potential for RPC to complement asynchronous message passing in PVM - both to expand the do...
2.1Message Passing Interface TheMessage Passing Interface(MPI)[2]is one of the popular programming models used for designing parallel applications. In our work, we use the MVAPICH2[11]software stack, a high performanceMPIimplementation over InfiniBand and RDMA networks, used by more than 2900 organ...
overhead of message passing. The MCIM is of much less complexity than the logic circuit based routers in most MPP systems. Comparison with SMP systems, it allows more processors contained in one “Big Node”. In MCIM parallel systems, computing nodes share the ...
