Addressing volume and latency overheads in 1d-parallel sparse matrix-vector multiplication
(Springer, 2017-08-09)The scalability of sparse matrix-vector multiplication (SpMV) on distributed memory systems depends on multiple factors that involve different communication cost metrics. The irregular sparsity pattern of the coefficient ... -
Latency-centric models and methods for scaling sparse operations
(Bilkent University, 2016-07)Parallelization of sparse kernels and operations on large-scale distributed memory systems remains as a major challenge due to ever-increasing scale of modern high performance computing systems and multiple con icting ... -
Partitioning models for scaling parallel sparse matrix-matrix multiplication
(Association for Computing Machinery, 2018)We investigate outer-product--parallel, inner-product--parallel, and row-by-row-product--parallel formulations of sparse matrix-matrix multiplication (SpGEMM) on distributed memory architectures. For each of these three ...
