This paper introduces a hybrid Associative memory/SIMD parallel processor, APPLES, which has been specifically designed for logic simulation. Its reviews the computational structure which permits parallel execution of logic gate evaluations in memory. This facilitates fine grain execution on a massive scale of the basic tasks inherent in VLSI logic simulation. Furthermore, unlike of her SIMD approaches the simulation is not limited to a unit delay model, complex delays such as inertial delays are permissible. The processor has been implemented in Verilog and assessed using ISCAS-85 benchmarks. Gate evaluation is executed in constant time, whereas updating fan-out lists expands with circuit size. However, the APPLES architecture enables this latter task to be parallelised subject to various system parameters. The most important constraint is identified as the fan-out memory access time relative to the scan rate of the associative memory.

The simulation of incompressible fluids is one of the important problem classes in computational fluid dynamics. We consider a simulation algorithm for the convection in binary fluid mixtures, a problem where a quite simple model describes a very complex behavior: In a parallel implementation on an IBM SP2, we investigate several implementation strategies involving different data layouts and communication organizations.

A code for Me simulation of X-ray diffraction pattern of a powder has been implemented on a massively parallel SIMD platform developed in the frame of the PQE2000 Project. The code allows the evaluation of the diffraction pattern of atomic-scale models of both perfectly ordered and disordered structures. The code has been wed to investigate the structures resulting from the non-equilibrium alloying process of an immiscible metallic couple (Ag-Cu).

We show that the latest version of massively parallelprocessing associative string processing architecture (System-V) is applicable for fast Monte Carlo simulation if an effective on-processor random number generator is implemented. Our lagged Fibonacci generator can produce 10(8) random numbers on a processor string of 12K PE-s. The time dependent Monte Carlo algorithm of the one-dimensional non-equilibrium kinetic Ising model perfoms 80 faster than the corresponding serial algorithm on a 300 MHz UltraSparc.

This paper considers the application of bio-inspired systems in the design of a novel and highly parallel image processing tool to detect edges within conventional grey-scale images. The aim of the work is to implement a new image processing architecture through evolvable hardware that is able to adapt according to the particular images encountered The simulation of such a system through the toe of evolutionary algorithms and genetic programming is demonstrated for rite conventional image processing operation of edge detection. Results al-e presented for this system and evaluated with respect to a conventional Sobel edge detector.

The bubble algorithm evaluated in this paper assures message deadlock freedom in k-ary n-cube network without wing virtual channels. This algorithm is based both on a dimension order routing (DOR) and on a restricted injection policy extended to the dimension changes. An exhaustive comparison between the bubble mechanism and the classical deterministic virtual channels solution is presented here. For that purpose, the message router of both proposals has been designed by using VHDL descriptions and the Synopsys VLSI CAD tool. Additionally :formal models of the routers, based on colored Petri nets, have been carried out together with simulation techniques in order to assure the validation of the results and shorten the design cycle. The performance evaluation of n-dimension tori highlights the benefits of the bubble algorithm as both the temporal delay and the necessary silicon area of the message router ape reduced.
