Tasking is the most significant feature included in the new OpenMP 3.0 standard. It was introduced to handle unstructured parallelism and broaden the range of applications that can be parallelized by OpenMP. This paper presents the design and implementation of the task model in the IBM XL parallelizing compilers. The task construct is significantly different from other OpenMP constructs. This paper discusses some of the unique challenges in implementing the task construct and its as- sociated synchronization constructs in the compiler. We also present a performance evaluation of our implementation on a set of benchmarks and applications. We identify limitations in the current implentation and propose solutions for further improvement.
