Linear Complexity Direct Solver for Fine-Grained Parallel Architectures
Wajih Boukaram, David Keyes, Sherry Li +2
We present factorization and solution phases for a new linear complexity direct solver designed for concurrent batch operations on fine-grained parallel architectures, for matrices…
H2Opus: A distributed-memory multi-GPU software package for non-local operators
Stefano Zampini, Wajih Boukaram, George Turkiyyah +2
Hierarchical -matrices are asymptotically optimal representations for the discretizations of non-local operators such as those arising in integral equations or from…
H2OPUS-TLR: High Performance Tile Low Rank Symmetric Factorizations using Adaptive Randomized Approximation
Wajih Boukaram, Stefano Zampini, George Turkiyyah +1
Tile low rank representations of dense matrices partition them into blocks of roughly uniform size, where each off-diagonal tile is compressed and stored as its own low rank factor…
Communication Complexity of the Fast Multipole Method and its Algebraic Variants
Rio Yokota, George Turkiyyah, David Keyes
A combination of hierarchical tree-like data structures and data access patterns from fast multipole methods and hierarchical low-rank approximation of linear operators from H-matr…
