Two electrical engineering applications from industry partners dealing with sparse matrices were analyzed regarding cache efficiency and scalability on modern multi core systems. Two different contemporary multi-core architectures have been investigated, namely Intel's Westmere and AMD's Magny-Cours. This paper can be regarded as a continuation of the investigations presented in [14] and [15]. In addition, the SuiteSparseQR library for efficiently computing QR factorizations of sparse matrices was evaluated regarding scalability and cache efficiency.
