Summary

Researchers from the University of California Berkeley, Lawrence Berkeley National Laboratory, and Georgia Institute of Technology examined Sparse Matrix Vector Multiplication (SpMV) kernel on multicore architectures, presenting two autotuned threaded implementations and benchmarking performance across four diverse architectures, comparing with leading MPI implementation. They found SpMV challenging due to irregular memory access, difficulty in exploiting instruction-level parallelism (ILP) and data-level parallelism (DLP), and low computational intensity. The study used a test suite of 14 sparse matrices, subdivided into four categories, to evaluate the performance of SpMV on multicore SMPs.
