Low-Synch Gram-Schmidt with Delayed Reorthogonalization for Krylov Solvers

Daniel Bielich, Julien Langou, Stephen Thomas +3

The parallel strong-scaling of Krylov iterative methods is largely determined by the number of global reductions required at each iteration. The GMRES and Krylov-Schur algorithms e…

Sphynx: a parallel multi-GPU graph partitioner for distributed-memory systems

Seher Acer, Erik G Boman, Christian A Glusa +1

Graph partitioning has been an important tool to partition the work among several processors to minimize the communication cost and balance the workload. While accelerator-based su…
