Grid Branch-and-Bound for Permutation Flowshop, the two can be used as a benchmark of maturity of parallel processing environment. Grid systems pose a number of hurdles which must be overcome in practical applications. We give a report on applying parallel branch-and-bound for flowshop in grid environment. Methods dealing with the complexities

An Experimental Comparison of Load Balancing Strategies in a Web Computing Environmentrograms. The PUB-Web library developed by us supports this kind of usage of computing resources. A major problem for the efficient execution of such parallel programs is load balancing. In the Web Computing context, this problem becomes more difficult because of the dynamic behavior of the underlyin

Scheduling Parallel Programs Based on Architecture–Supported Regionstational functions. Multi CMP (Chip Multi-Processor) systems can be composed as a set of dedicated and general purpose computational modules interconnected by a global data exchange network. The paper proposes special program scheduling algorithms for such systems. Dedicated CMP modules assumed in t

Genetic Algorithm Calibration for Two Objective Scheduling Parallel Jobs on Hierarchical Gridse, jobs are allocated to a suitable Grid site, while at the second stage, local scheduling is independently applied to each site. In this environment, one of the big challenges is to provide a job allocation that allows more efficient use of resources and user satisfaction. In general, the criteria

Portable Explicit Threading and Concurrent Programming for MPI Applicationsupport for concurrency. Due to online query processing and multi-user operation, we need to concurrently maintain and analyze the data. While the Portable Operating System Interface (POSIX) defines a thread interface that is widely available, and while modern implementations of the Message Passing I

Parallelization of an XML Data Compressor on Multi-coresents our research aimed at building parallel XML compressors, using Java and OpenMP (with C++). Our findings show that OpenMP is a preferred choice achieving better results than Java using a multi-core platform.

Comparing CUDA, OpenCL and OpenGL Implementations of the Cardiac Monodomain Equationsomprises a nonlinear system of partial differential equations and its numerical solution represents a very intensive computational task due to the required fine spatial and temporal resolution. Recent studies have shown that the use of GPU as a general purpose processor can greatly improve the perfo
