Consider any known sequential algorithm for matrix multiplication over an arbitrary ring with time complexity O(N a ), where 2 < a [ 3. We show that such an algorithm can be parallelized on a distributed memory parallel computer (DMPC) in O(log N) time by using N a /log N processors. Such a parallel
We present a new fast and scalable matrix multiplication algorithm called DIMMA (distribution-independent matrix multiplication algorithm) for block cyclic data distribution on distributed-memory concurrent computers. The algorithm is based on two new ideas; it uses a modified pipelined communicatio
The R-matrix and Logarithmic Derivative methods are numerically very stable and are therefore ideal for integrating the large sets of coupled second-order linear differential equations which arise in non-exchange scattering problems (e.g., electron scattering by atoms and molecules). These calculati
