The evolution of the architecture of massively parallel computers is progressing toward systems with a hierarchical hardware design where each node is a shared memory system with several multi-core CPUs. There is consensus in the HPC community about the need to increment the efficiency of the programming paradigms used to exploit massive parallelism, if we are to make a full use of the advantages offered by these new architectures.
llc
is a language where parallelism is expressed using OpenMP compiler directives. In this paper we focus our attention on the automatic generation of hybrid
