Abstract

This paper presents a set of proposals for the OpenMP shared-memory programming model oriented towards the definition of thread groups in the framework of nested parallelism. The paper also describes the additional functionalities required in the runtime library supporting the parallel execution. The extensions have been implemented in the OpenMP NanosCompiler and evaluated in a set of real applications and benchmarks. In this paper we present experimental results for one of these applications.
