In tins impel we discuss the implementation of a simple pedestrian simulation that, uses a multi agent based design pattern developed by the CoSMoS research group Given the nature of Multi Agent Systems (MAS), parallelprocessing techniques are inevitably used in their implementation Most, of these approaches rely on conventional parallel programming techniques;such as threads, Message Passing Interface (MPI) and Remote Method Invocation (RMI) the CoSMoS design pattern us are founded on the use of Communicating Sequential Processes (CSID) a pal and computing paradigm that emphasises a process or rather than object oriented programming perspective

Numerical homogenization is used for up-scaling of a linear elasticity tensor of strongly heterogeneous micro-structures Utilized approach assumes presence of a periodic micro-structure and thus periodic boundary conditions Rotated trilinear Rannacher-Turek finite elements are used for the discretization while a parallel PCG method is used to solve arising large-scale systems with sparse, symmetric, positive semidefinite matrices Applied preconditioner is based on modified incomplete Cholesky factorization MIC(0) the test problem represents a trabecular bone tissue, and takes into account only the elastic response of the solid phase the voxel micro-structure of the bone is extracted from a high resolution computer tomography image Numerical tests performed on parallel computers demonstrate the efficiency of the developed algorithm

In tins paper we take a look at what the new Quad-Core Intel Xeon Processor code name Nehalem brings to high performance computing. We compare Intel Xeon 5400 series based system with a server utilizing his successor the new Intel Xeon X5560. We compare both CPU generations utilizing dual socket platform us using a number of HPC benchmarks. the results clearly prove that the new Intel Xeon processor 5500 family provide significant performance advantage on typical HPC workloads and demonstrate to be a right choice for many of HPC installations.

Real-time syntactic pattern recogniton imposes strict computing time constraints on new techniques developed. Recently, a method for an analysis of hand postures of the Polish Sign Language based on the ETPL(k) graph grammars (Flasinski: Patt. Recogn. 26 (1993);1-16;theor. Comp. Sci. 201 (1998), 189-231) has been constructed. In order to make a system implemented more feasible for the users, a research into parallelization of a pattern recognition process has been led. Possible techniques of tasks distribution have been tested. It has allowed us to define an optimum strategy of parallelization. the results are presented in the paper.

In this paper we propose a strategy of partial data replication for efficient parallel computing of the Discrete Wavelet Transform in a distributed memory environment. the key is to avoid the communications needed between computation of different wavelet levels, by replicating part of the data and part;of the computations, avoiding completely communications (except maybe at the setup phase). A similar idea. was proposed in a paper by Chaver et. al.;however, they proposed to replicate completely the data, which can require too much memory in each processor. In this work we have determined exactly how many data items shall be needed for each processor, in order to compute the DWT without extra communications and using only the memory strictly necessary.
this paper proposes a reconfigurable multi-core architecture, called hyperscalar that enables many scalar cores to be united dynamically as a larger superscalar processor to accelerate a thread. To accomplish this, we...
