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…
Adaptive Sketching Based Construction of H2 Matrices on GPUs
Wajih Halim Boukaram, Yang Liu, Pieter Ghysels +1
We develop a novel linear-complexity bottom-up sketching-based algorithm for constructing a matrix, and present its high performance GPU implementation. The construction algo…
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…
Hierarchical Matrix Operations on GPUs: Matrix-Vector Multiplication and Compression
Wajih Halim Boukaram, George Turkiyyah, David E. Keyes
Hierarchical matrices are space and time efficient representations of dense matrices that exploit the low rank structure of matrix blocks at different levels of granularity. The hi…
Batched QR and SVD Algorithms on GPUs with Applications in Hierarchical Matrix Compression
Wajih Halim Boukaram, George Turkiyyah, Hatem Ltaief +1
We present high performance implementations of the QR and the singular value decomposition of a batch of small matrices hosted on the GPU with applications in the compression of hi…
