In this paper we present the design and implementation of tasks in the context of the \ompi\ \openmp\ compiler. The modular architecture of \ompi's runtime system allows a wide range of choices for experimenting with \openmp\ structures. We present two fully-fledged implementations of tasks: one based on \posix\ threads, with the addition of a tasking layer, and another one based on an almost unmodified user-level threading library. Both allow the tuning of their scheduling parameters so as to optimize memory consumption and execution times, resulting in highly competitive performance.
