Most current shared-memory parallel programming environments are based on thread packages that allow the exploitation of a single level of parallelism. These thread packages do not enable the spawning of new parallelism from a previously activated parallel region. Current initiatives (like OpenMP) include in their definition the exploitation of multiple levels of parallelism through the nesting of parallel constructs.This paper analyzes the requirements towards an efficient multi-level parallelization and reports some conclusions gathered from the experience in the parallelization of two benchmark applications. The underlying system is based on: i) an OpenMP compiler which accepts some extensions to the original definition and ii) a user-level threads library that supports the exploitation of both fine-grain and multi-level parallelism.
