IA64 Oriented OpenMP Compiler: Design and Implementation of Fortran Front End

摘要

This paper presents an OpenMP compiler Fortran Front End. It introduces principles and algorithms to deal with the implicit data parallelism, which is directed by WORKSHARE directive in OpenMP Fortran API V2.0. For implementation, automatic parallel computation division by compiler is achieved by front end's converting implicit data parallelism to explicit one in Very High WHIRL. In addition, this paper presents some optimization techniques to handle compiler-generated redundant synchronization and consistent DO loop. At the end, a performance experiment is given to prove the effectiveness of mentioned strategy.
