Reducing software overheads in parallel linear algebra libraries

Strazdins, Peter


Software overheads can be a significant cause of performance degradation in parallel numerical libraries. This paper examines the nature and extent of software overheads in an implementation of parallel LAPACK on distributed memorymultiprocessors, where block-partitioned algorithms with a general block-cyclic matrix distribution scheme present special challenges. It then describes various techniques that have been used to reduce these overheads, and evaluates their effectiveness. While there is...[Show more]
