llc
is a language designed to extend OpenMP to distributed memory systems. Work in progress on the implementation of a compiler that translates
llc
code and targets distributed memory platforms is presented. Our approach generates code for communications directly on top of MPI. We present computational results for two different benchmark applications on a PC-cluster platform. The results reflect similar performances for the
llc
compiled version and an
ad-hoc
MPI implementation, even for applications with fine-grain parallelism.
