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.

A real-time fault-tolerant multicast protocol is necessary for obtaining high performance in operating distributed real-time computing systems. The purpose of this paper is to show the efficiency of RFRM (Release-time based Fault-tolerant Real-time Multicast) protocol which is based on the idea of attaching the official release time to each multicast message. As a part of this, a real-time simulation based on the TMO structuring scheme is conducted to evaluate the proposed approach. We experiment a real-time multicast model which does not receive ack-messages toward reducing the message traffic on the network by employing fault detection mechanism. simulation results promised the efficiency of the proposed real-time multicast protocol.
