In this paper we present Ariadne, a compiler that extracts parallelism from recursive function calls. Ariadne takes as input C code enhanced with directives for recursive functions and automatically produces code for multi-core architectures. It produces code for the POSIX standard, the OpenMP model and the Cilk programming language, which run on a wide variety of computing systems. Ariadne also produces code for SL, a programming language proposed for the SVP processor and model. This is of special interest, since we can map certain function calls onto SVP, which contain inherent parallelism that cannot efficiently be expressed in other programming models. Ariadne is the only compiler that extracts parallelism from various forms of recursive functions using directives. It is also the only compiler that handles all forms of reduction operations for addition, subtraction, multiplication and division. The experimental results are very promising showing significant speedups in all benchmarks.
