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…
Asynchronous One-Level and Two-Level Domain Decomposition Solvers
Christian Glusa, Paritosh Ramanan, Erik G. Boman +2
Parallel implementations of linear iterative solvers generally alternate between phases of data exchange and phases of local computation. Increasingly large problem sizes on more h…
