Parallel Algorithms for Sparse Matrix Multiplication and Join-Aggregate Queries
Summary: Massively parallel algorithms for sparse matrix multiplication and for join-aggregate queries with tree-structured join hypergraphs and arbitrary output attributes. Achieves asymptotic improvements over prior work, with matrix multiplication optimal in the semiring model. (summarized by gpt-5-mini on Feb 09 2026)
