class Ompss(Package):
    """OmpSs is an effort to integrate features from the StarSs programming
    model developed by BSC into a single programming model. In
    particular, our objective is to extend OpenMP with new directives
    to support asynchronous parallelism and heterogeneity (devices
    like GPUs). However, it can also be understood as new directives
    extending other accelerator based APIs like CUDA or OpenCL. Our
    OmpSs environment is built on top of our Mercurium compiler and
    Nanos++ runtime system.
