| Abstract | Implementing linear algebra kernels on distributed memory parallel computers raises the problem of data distribution of matrices and vectors among the processors Block cyclic distribution seems to suit well for most algorithms But one has to choose a good compromise for the size of the blocks to achieve a good e ciency and a good load balancing This choice heavily depends on each operation so it is essential to be able to go from one distribution to another very quickly We present here the algorithms we implemented in the ScaLAPACK library A complexity study is then made that proves the e ciency of our solution Timing results on a network of SUN workstations and the Cray T D using PVM corroborates the results |
