Computation of Dendrites on Parallel Distributed Memory Architectures
نویسنده
چکیده
A code for simulating the solidi cation of a pure material from its undercooled melt based on a phase eld approach has been written for parallel distributed memory architectures using MPI. The numerical scheme is based on nite di erences and results in large sparse non-linear systems which are solved by a backtracking line search modi cation of Newton's method combined with GMRES. Experiments conducted on an IBM SP2 and networks of Sun Ultra 5 workstations show that the code scales well with the number of processors.

A High Performance Parallel IP Lookup Technique Using Distributed Memory Organization and ISCB-Tree Data Structure
The IP Lookup Process is a key bottleneck in routing due to the increase in routing table size, increasing traıc and migration to IPv6 addresses. The IP address lookup involves computation of the Longest Prefix Matching (LPM), which existing solutions such as BSD Radix Tries, scale poorly when traıc in the router increases or when employed for IPv6 address lookups. In this paper, we describe a ...

متن کاملA Message-Passing Distributed Memory Parallel Algorithm for a Dual-Code Thin Layer, Parabolized Navier-Stokes Solver
In this study, the results of parallelization of a 3-D dual code (Thin Layer, Parabolized Navier-Stokes solver) for solving supersonic turbulent flow around body and wing-body combinations are presented. As a serial code, TLNS solver is very time consuming and takes a large part of memory due to the iterative and lengthy computations. Also for complicated geometries, an exceeding number of grid...
متن کاملAutomatic Scheduling for Cache Only Memory Architectures
For parallel and distributed systems to gain wider acceptance than they have to date, they must become significantly easier to program. Fundamentally, parallel programming is more difficult than sequential programming as long as data and computation must be distributed by the programmer. Cache Only Memory Architectures (COMAs) provide a Distributed Shared Memory (DSM) where data distribution is...
متن کاملParallel Implementation of Schönhage's Integer GCD Algorithm
We present a parallel implementation of Schönhage’s integer GCD algorithm on distributed memory architectures. Results are generalized for the extended GCD algorithm. Experiments on sequential architectures show that Schönhage’s algorithm overcomes other GCD algorithms implemented in two well known multiple-precision packages for input sizes larger than about 50000 bytes. In the extended case t...
