The use of BLAS3 in linear algebra on a parallel processor with a hierarchical memory. (English) Zbl 0632.65024

Block algorithms are used for the LU-decomposition and the Gram-Schmidt algorithm in order to compensate for the narrow memory bandwidth and small cache size of the ALLIANT FX/8. Thus more local use of data is obtained. Why not build better hardware?
