A survey of the NARSIM C/S middleware

This document describes the Client/Server system architecture of NARSIM - the NLR Air Traffic control Research Simulator- focussing on the socalled middleware: the infrastructure that enables all the seperate parts of the simulator to interact with each other. To show the full scope of the architecture, first a somewhat abstract architecture...

Structured parallelization of a multi-block Navier-Stokes solver targeting distributed memory platforms

SOLEQS is a sequential three-dimensional multi-block multi-zone compressible Navier-Stokes solver, produced by NLR. In this paper is described how this large-scale application code in the order of 120,000 lines can be parallelized towards different computing platforms in a structured and manageable way. This paralellization is done step-wise,...

Implementation aspects of a decompressor for compressed METEOSAT data on a VME/68000 system

This report describes the results of a feasibility study into some aspects of a proposed METEOSAT image data compression unit. The study was performed to support the preparation of a proposal for ESOC. For the considered algorithms (ESTEC 1 & MEANDER 1) an estimate of the needed processing power based on the 68000 instruction set was made. This...
