Título: OmpSs on Embedded Hardware

Resumo: In this talk, we will show the development of the OmpSs programming model in the context of the Mont-Blanc and AXIOM european projects. Mont-Blanc aims to provide low-cost embedded hardware to build a supercomputer. The main prototype is based on the Samsung Exynos chip, featuring 2 ARM Cortex A15 cores with an OpenCL-capable integrated MALI GPU. Around the main prototype we have also built a few smaller mini-clusters based on the ARM 64-bit architecture. In the AXIOM project, we are building an additional mini-cluster with an integrated FPGA based on the Xilinx Zynq chip. OmpSs allows to express the parallelism to exploit GPU and FPGA accelerators. In the talk, we will present the way of coding applications, and the results obtained Short Bio: Xavier Martorell received the M.S. and Ph.D. degrees in Computer Science from the Technical University of Catalunya (UPC) in 1991 and 1999, respectively. Since 1992 he has lectured on operating systems, parallel runtime systems and OS administration. He has been an associate professor in the Computer Architecture Department at UPC since 2001. His research interests cover the areas of operating systems, runtime systems, compilers and applications for high-performance multiprocessor systems. Prof. Martorell has participated in several long-term research projects with other universities and industries, primarily in the framework of the European Union ESPRIT, IST, FET, FP6, FP7, and H2020 programs. He spent one year working with the BG/L team in the IBM Watson Research Center. He has coauthored more than 80 publications in international journals and conferences. He has co-advised six Ph.D. theses and he is currently advising 2 PhD students. He is currently the Manager of the Parallel Programming Models team at the Barcelona Supercomputing Center. He has been participating in the HiPEAC Network of Excellence and in the SARC, ACOTES, and Intone, POP, ENCORE, MontBlanc I, and currently in MontBlanc (II and III), DEEP-ER and the AXIOM European projects.
