Partitioning Trillion-edge Graphs in Minutes
George M Slota, Sivasankaran Rajamanickam, Karen Devine +1
We introduce XtraPuLP, a new distributed-memory graph partitioner designed to process trillion-edge graphs. XtraPuLP is based on the scalable label propagation community detection…
Task Parallel Incomplete Cholesky Factorization using 2D Partitioned-Block Layout
Kyungjoo Kim, Sivasankaran Rajamanickam, George Stelle +2
We introduce a task-parallel algorithm for sparse incomplete Cholesky factorization that utilizes a 2D sparse partitioned-block layout of a matrix. Our factorization algorithm foll…
Basker: A Threaded Sparse LU Factorization Utilizing Hierarchical Parallelism and Data Layouts
Joshua Dennis Booth, Sivasankaran Rajamanickam, Heidi K. Thornquist
Scalable sparse LU factorization is critical for efficient numerical simulation of circuits and electrical power grids. In this work, we present a new scalable sparse direct solver…
