However, most current distributed memory MIMD architectures have too high communication latencies for exploiting all parallelism available. To cope with this, latencies must be avoided by coarsening the granularity and by message fusion. However, both techniques limit the concurrency, thereby reducing the scalability. In this paper, an implementation of a parallel LU decomposition algorithm for linear programming bases is presented for distributed memory parallel computers with noticable communication latencies. Several design decisions due to latencies, including data distribution and load balancing techniques, are discussed. An approximate performance model is set up for the algorithm, which allows to quantify the impact of latencies on its performance. Finally, experimental results for an Intel iPSC/860 parallel computer are reported and discussed.}, language = {en} } @inproceedings{DeuflhardHege1994, author = {Deuflhard, Peter and Hege, Hans-Christian}, title = {Scientific Computing in der Theoretischen Physik - Collected Abstracts}, booktitle = {Tagung organisiert von der DMV-Fachgruppe Scientific Computing in Kooperation mit dem GAMM Fachausschuss Scientific Computing}, address = {Berlin}, year = {1994}, language = {en} } @inproceedings{GrammelBackWunderlingetal.1994, author = {Grammel, Martin and Back, Godmar and Wunderling, Roland and Hege, Hans-Christian}, title = {Ein paralleles C++/C-Programmiermodell f{\"u}r ein objektorientiertes B\&C-Framework}, volume = {13}, booktitle = {GI/ITG-Workshop, Sept.1994, Mitteilungen der Fachgruppe PARS der Gesellschaft f{\"u}r Informatik (GI)}, address = {Potsdam}, pages = {50 -- 59}, year = {1994}, language = {en} } @inproceedings{WunderlingGrammelHege1994, author = {Wunderling, Roland and Grammel, Martin and Hege, Hans-Christian}, title = {Parallele LU-Zerlegung großer, unsymmetrischer, d{\"u}nn besetzter Matrizen bei hohen Kommunikationslatenzen}, volume = {13}, booktitle = {GI/ITG-Workshop, Sept.1994, Mitteilungen der Fachgruppe PARS der Gesellschaft f{\"u}r Informatik (GI)}, address = {Potsdam}, pages = {191 -- 200}, year = {1994}, language = {en} } @article{Hege1994, author = {Hege, Hans-Christian}, title = {Scaling study of pure SU(3) theory - the QCD-TARO collaboration}, volume = {34}, journal = {Nucl.
