Heterogeneous tasking on SMP/FPGA SoCs: The case of OmpSs and the Zynq

OmpSs is a directive-based programming model that uses OpenMP-like directives, that allow to execute the tasks annotated on both the SMPs and as FPGA kernels on modern SoC processors, like the Xilinx Zynq platform. OmpSs includes the support for accelerators (MIC, GPUs, FPGAs) and task dependencies, like OpenMP 4.0 will support. In this paper we present our approach for the support of FPGAs and the Zynq SoC, the current status of the implementation, its analysis and performance evaluation
