In dynamic bulk synchronous computations, processors may change their workloads from phase to phase. Such workload change will possibly increase the duration of a phase and the overall parallel execution time. Therefore, it is necessary to redistribute workload at runtime to reduce the parallel time. However, such workload redistribution at runtime can be expensive and the overhead of frequent runtime workload redistribution may exceed the benefit of workload redistribution and balancing. The problem of finding the optimal period of runtime workload redistribution for dynamic bulk synchronous computations is motivated by the combined consideration of parallel execution time and system overhead for workload redistribution and balancing. We develop an analytical method to solve the problem in heterogeneous computing systems. We also demonstrate numerical data of the analytical method and simulation results that verify the analytical data.
simulation is a low cost alternative to experimentation on real-world physical systems. Grid technology enables coordinated use of and secure access to distributed computing resources and data sources. The service-ori...

This paper presents the parallel numerical simulation of 3-D compressible strongly rotating viscous flows by solving Navier-Stokes equations using meshless Least Square Kinetic Upwind Method (LSKUM) solver. The paper describes the LSKUM solver and also addresses the various issues that arise while parallelisation is carried out for LSKUM-NS code for viscous compressible flows using a typical distributed memory architecture. The computational fluid dynamic (CFD) simulation showed a large sized subsonic pocket with a vortex ahead of the stationary body. The parallel meshless CFD code coupled with diffusion and optimization code is capable of solving many viscous rotating flows.

Multiprocessor system-on-chip (MP-SoC) platforms represent an emerging trend for embedded multimedia applications. To enable MP-SoC platforms, scalable communication-centric interconnect fabrics, such as networks-on-chip (NoC), have been recently proposed. The shared memory represents one of the key elements in designing MP-SoCs, since its function is to provide data exchange and synchronization support. In this paper, a distributed shared memory architecture has been explored, that is suitable for low-power on-chip multiprocessors based on NoC. In particular, the paper focuses on the energy/delay exploration of on-chip physically distributed and logically shared memory address space for MP-SoCs based on a parameterizable NoC. The data allocation on the physically distributed shared memory space is dynamically managed by an on-chip Hardware Memory Management Unit. Experimental results show the impact of different NoC topologies and distributed shared memory configurations for a selected set of parallel benchmark applications from the power/performance perspective.
