An Efficient Algorithm for Gray-to-Binary Permutation on Hypercubes
Ho, Ching-Tien; Johnsson, S. Lennart; Raghunath, M.T. (1992)Both Gray code and binary code are frequently used in mapping arrays into hypercube architectures. While the former is preferred when communication between adjacent array elements is needed, the latter is preferred for ... -
Load-Balanced LU and QR Factor and Solve Routines for Scalable Processors with Scalable I/O
Brunet, Jean-Philippe; Pederson, Palle; Johnsson, S. Lennart (1994)The concept of block-cyclic order elimination can be applied to out-of-core LU and QR matrix factorizations on distributed memory architectures equipped with a parallel I/O system. This elimination scheme provides load ...
