As the system size of supercomputers and datacenters increases, cost-efficient networks become critical in achieving good scalability on those systems. High-radix routers reduce network cost by lowering the network diameter while providing a high ...
A parallel algorithm has perfect strong scaling if its running time on $P$ processors is linear in $1/P$, including all communication costs. Distributed-memory parallel algorithms for matrix multiplication with perfect strong scaling have only recently ...
The main purpose of this paper is to develop stable versions of some Krylov subspace methods for solving linear systems of equations $Ax = b$. As in the case of Paige and Saunders's SYMMLQ [SIAM J. Numer. Anal., 12 (1975), pp. 617–624], our algorithms ...
