Implementing OpenMP for Clusters on Top of MPI

  • Conference paper
Recent Advances in Parallel Virtual Machine and Message Passing Interface (EuroPVM/MPI 2005)

Part of the book series: Lecture Notes in Computer Science ((LNPSE,volume 3666))

Abstract

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.

This work has been partially supported by the Canary Islands government, contract PI2003/113, and also by the EC (FEDER) and the Spanish MCyT (Plan Nacional de I+D+I, contracts TIC2002-04498-C05-05 and TIC2002-04400-C03-03).
