Hierarchical low-rank compression exploiting symmetric boundary integral equations in transmission scattering
Yasuhiro Matsumoto, Taizo Maruyama, Qianxiang Ma +1
We propose an approach using matrix symmetry to accelerate hierarchical low-rank compression for wave transmission scattering. For Helmholtz transmission problems, we introduce a s…
Emulation of Complex Matrix Multiplication based on the Chinese Remainder Theorem
Yuki Uchino, Qianxiang Ma, Toshiyuki Imamura +2
Modern computing architectures feature low-precision matrix multiplication units that achieve substantially higher throughput than their high-precision counterparts. Motivated by t…
An inherently parallel H2-ULV factorization for solving dense linear systems on GPUs
Qianxiang Ma, Rio Yokota
Hierarchical low-rank approximation of dense matrices can reduce the complexity of their factorization from O(N^3) to O(N). However, the complex structure of such hierarchical matr…
Scalable Linear Time Dense Direct Solver for 3-D Problems Without Trailing Sub-Matrix Dependencies
Qianxiang Ma, Sameer Deshmukh, Rio Yokota
Factorization of large dense matrices are ubiquitous in engineering and data science applications, e.g. preconditioners for iterative boundary integral solvers, frontal matrices in…
