SparseX-PIM: Sparse Linear Algebra on Processing-in-Memory

Sparse linear algebra is a fundamental workload in scientific computing and machine learning, but its performance is severely constrained by memory bandwidth. Processing-in-memory (PIM) has shown great potential for sparse linear algebra, yet its efficiency is heavily bottlenecked by irregular computation and memory ac...
