Abstract

A new grid programming environment for remote procedure call (RPC) based master-worker type task parallelization is presented. The environment is realized through the use of a set of compiler directives, called OpenGR, and is implemented in the present study based on the Omni OpenMP compiler system and Ninf-G grid-enabled RPC system as a parallel execution mechanism. Using OpenGR directives, existing sequential applications can be readily adapted to the grid environment as master-worker parallel programs using the RPC architecture. The combination of OpenGR and OpenMP directives also allows for the hybrid parallelization of sequential programs, supporting both synchronous and asynchronous parallelism.
