MPI-FAUN: An MPI-Based Framework for Alternating-Updating Nonnegative Matrix Factorization
Ramakrishnan Kannan, Grey Ballard, Haesun Park
Non-negative matrix factorization (NMF) is the problem of determining two non-negative low rank factors and , for the given input matrix , such that . NMF…

A communication-avoiding parallel algorithm for the symmetric eigenvalue problem
Edgar Solomonik, Grey Ballard, James Demmel +1
Many large-scale scientific computations require eigenvalue solvers in a scaling regime where efficiency is limited by data movement. We introduce a parallel algorithm for computin…

Hypergraph Partitioning for Sparse Matrix-Matrix Multiplication
Grey Ballard, Alex Druinsky, Nicholas Knight +1
We propose a fine-grained hypergraph model for sparse matrix-matrix multiplication (SpGEMM), a key computational kernel in scientific computing and data analysis whose performance…
