Abstract
In this paper, the authors deal with algorithmic issues on heterogeneous pl atforms. They concentrate on dense linear algebra kernels, such as matrix m ultiplication or LU decomposition. Block-cyclic distribution techniques use d in ScaLAPACK are no longer sufficient to balance the load among processor s running at different speeds. The main result of this paper is to provide a static data distribution scheme that leads to an asymptotically perfect l oad balancing for LU decomposition, thereby providing solid foundations tow ard the design of a cluster-oriented version of ScaLAPACK.
