Parallel Performance of a Code Using Multidimensional FFTs SP is presented based on an algorithm for sound propagation through a finite inhomogeneous medium. Techniques for improving the serial and parallel efficiency of such codes is described, and the use of software tools to aid the process are illustrated.

Alternating Direction Implicit Methods on Distributed and Shared Memory Parallel Computersional space community. We shall describe different implementations of a 3D alternating direction implicit (ADI) magnetohydrodynamic (MHD) simulation code on distributed and shared memory parallel and parallel/vector computers. The specific architectures considered are the IBM SP and Silicon Graphics

Simulating Galaxy Formation on SMPSc multi-processor configuration (SMP). Parallelization is achieved using the parallelization directives in the MIPSpro Fortran 77 instruction set. We examine the performance of the code and find excellent scaling up to 8 processors. The maximum number of process elements is limited by race condition

Data Parallelism in Java’s shortcomings with respect to data-parallel programming and presents workarounds. The technical contributions of this paper are twofold: a source-to-source transformation that maps foral l statements into efficient multi-threaded Java code, and an optimization strategy that minimizes the number of

An Age-Threshold Algorithm for Garbage Collection in Log-Structured Arrays and File Systemsic idea of our algorithm is that segments that have been recently filled by writes from the system should be forced to wait for a certain amount of time (the age-threshold) before they are allowed to become candidates for garbage collection. Among segments that pass the age-threshold, we select ones

In this paper we address the exploitation of pipelining parallelism in query processing on small multiprocessor environments. We present DTE/R, a strategy for executing pipelining segments of ar

Speeding up Automatic Parallel I/O Performance Optimization in Pandantific applications, impose a great challenge in selecting high-quality I/O plans for an anticipated I/O workload in a target execution environment. Previous research has shown that a model-based approach that uses a performance model of the parallel I/O system to predict the performance of the para
