Tackling Parallelization Challenges of Randomized Preconditioners With Dependency Tracking
Tianyu Liang, Chao Chen, Yotam Yaniv +6
Incomplete Cholesky (IC) preconditioners are the standard black-box, memory-efficient first resort for large graph Laplacian systems, but classical IC can break down on irregular g…

An O(N) distributed-memory parallel direct solver for planar integral equations
Tianyu Liang, Chao Chen, Per-Gunnar Martinsson +1
Boundary value problems involving elliptic PDEs such as the Laplace and the Helmholtz equations are ubiquitous in mathematical physics and engineering. Many such problems can be al…
