Invited Talk: Discussion on Hash-Table Approaches for Efficient Sparse Tensor Contraction
DescriptionSparse tensor contraction (SpTC) is a crucial operation in high-performance applications, particularly in computational chemistry, high-order tensor decompositions, and quantum sciences. This talk will explore the performance challenges associated with SpTC and review current state-of-the-art solutions. We will focus on hash-table approaches, discussing the key features of hash table design that significantly impact performance. Additionally, a novel hash method will be introduced, featuring a fast hash function with guaranteed collision-free operations to efficiently support SpTC computations.
