 OmpSs-2 is a programming model composed of a set of directives and library routines that can be used in conjunction with a high-level programming language in order to develop concurrent applications. Its name originally comes from two other programming models: **OpenMP** and **StarSs**. The design principles of these two programming models constitute the fundamental ideas used to conceive the OmpSs philosophy.

 OmpSs-2 **thread-pool** execution model differs from the **fork-join** parallelism implemented in OpenMP.
