Using PMD to Parallel-Solve Large-Scale Navier-Stokes Equations. Performance Analysis on SGI/CRAY-T3E Machine
"... Abstract. PMD (Parallel Multi-domain Decomposition) is an MPI based Fortran 90 module which objective is to parallel-solve positive definite linear elliptic second order equations. It has been used to solve unsteady Navier-Stokes equations in order to simulate an axisymmetric incompressible viscous ..."

fluid flow inside a centrifugal pump. In this paper, we will present a brief description of the implementation and will discuss the performance measurements obtained on the SGI/CRAY T3E parallel machine. 1
Fast Parallel Algorithms for Short-Range Molecular Dynamics
- JOURNAL OF COMPUTATIONAL PHYSICS
, 1995
"... Three parallel algorithms for classical molecular dynamics are presented. The first assigns each processor a fixed subset of atoms; the second assigns each a fixed subset of inter-atomic forces to compute; the third assigns each a fixed spatial region. The algorithms are suitable for molecular dyn ..."

. The algorithms are tested on a standard Lennard-Jones benchmark problem for system sizes ranging from 500 to 100,000,000 atoms on several parallel supercomputers -- the nCUBE 2, Intel iPSC/860 and Paragon, and Cray T3D. Comparing the results to the fastest reported vectorized Cray Y-MP and C90 algorithm shows
CRAY T3E and SGI Origin2000: Merging Architectures from the User’s Point of View
"... While the T3E is very well established as a highly parallel machine in many compute intensive environments, large Origin2000 sites still have to optimize their usage profile to get effective cycles for parallel codes even for moderate numbers of processors. The paper compares T3E and Origin2000 syst ..."

Using the parallel MICOM on SGI multiprocessors and the Cray T3D
, 1995
"... This paper is intended to introduce users who are familiar with running the uniprocessor version of MICOM to the parallel version developed for SGI multiprocessors and the Cray T3D. It will explain how this code works, how it differs from the standard MICOM, and what to be aware of if you want to ..."

Parallel rendering of 3D AMR data on the SGI/Cray T3E
- In: Proceedings of Frontiers ’99 the Seventh Symposium on the Frontiers of Massively Parallel Computation
, 1999
"... This paper describes work-in-progress on developing parallel visualization strategies for 3D Adaptive Mesh Refinement (AMR) data. AMR is a simple and powerful tool for modeling many important scientific and engineering problems. However, visualization tools for 3D AMR data are not generally availabl ..."
A Software-level Cray T3D Emulation Package for SGI Shared-memory Multiprocessor Systems
, 1995
"... This paper describes a library package that allows FORTRAN programs written to run on the Cray T3D using the get/put communication routines to be compiled and run on single and multiprocessor SGI systems. This package allows parallel programs to be developed on easily available SGI workstations a ..."

The state of the art in distributed query processing
- ACM Computing Surveys
, 2000
"... Distributed data processing is fast becoming a reality. Businesses want to have it for many reasons, and they often must have it in order to stay competitive. While much of the infrastructure for distributed data processing is already in place (e.g., modern network technology), there are a number of ..."

Implementation of a Portable Nested Data-Parallel Language
- Journal of Parallel and Distributed Computing
, 1994
"... This paper gives an overview of the implementation of Nesl, a portable nested data-parallel language. This language and its implementation are the first to fully support nested data structures as well as nested dataparallel function calls. These features allow the concise description of parallel alg ..."

. It runs on the Connection Machine CM-2, the Cray Y-MP C90, and serial machines. We compare initial benchmark results of Nesl with those of machine-specific code on these machines for three algorithms: least-squares line-fitting, median finding, and a sparse-matrix vector product. These results show
The Performance and Scalability of SHMEM and MPI-2 One-Sided Routines on a SGI Origin 2000 and a Cray T3E-600
