We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.
Benchmarking a Shared Memory System
Ronald Kriemann, Jens Burmeister and Rainer Kleinrensing
For the evaluation of shared memory systems several programs were chosen and ported to different, today available computer systems. These applications represent important aspects of our numerical and algorithmic research. Beside the evaluation of the processor performance, the programs were chosen to test the scalability of the systems w.r.t. memory and the number of CPUs. The main characteristics of the benchmarked computer systems and the results from the individual benchmarks are presented. Furthermore, problems which occurred while porting the programs are discussed.
