José-Ramón Herrero,

Universitat Politècnica de Catalunya


In this talk we will present recent research focused on producing high performance Dense Linear Algebra (DLA) codes on Asymmetric Multicore Processors (AMP). We tailor the study on representative asymmetric multicore processors present in an ARM big.LITTLE architecture specifically designed for energy efficiency. We will discuss the challenges posed by these architectures and the way we have exploited parallelism in order to produce high performance implementations of the most significant DLA kernels within BLAS and LAPACK. We will stress the need for malleability and dynamically adapting to the available resources.


José-Ramón Herrero holds a position as associate professor in the Computer Architecture Department at UPC, BarcelonaTech. He has been teaching in the Barcelona School of Informatics (FIB) since 1994 where he has taught fourteen different courses corresponding to several areas (Computer Architecture, Operating Systems, and Parallel Programming). He has carried out the duties of Vice-Dean Head of Academic Studies and Vice-dean for Institutional and International Relations at Barcelona School of Informatics (FIB). He has combined these management and teaching tasks with research in HPC, mainly in the field of High Performance Scientific Computing.
