Multithreaded Dense Linear Algebra on Asymmetric Multi-core Processors

“…Models were important in the characterization of the operations in order to gain insights of the potential bottlenecks of each one. Those models were built for BLAS kernels [27,9] and LAPACK operations [29,8] on both symmetric and asymmetric platforms. Moreover, analyses about fault tolerance and their cost were performed as a critical issue on very low-power platforms [33,7,25].…”
