Many important applications have a heterogeneous structure, and can be implemented efficiently only with task parallelism. This paper presents a set of extensions to Fortran to build task parallel programs for multicomputers consisting of distinct nodes either private memory parallel machines, or autonomous computers connected by a high speed network. The design of these extensions is driven by the following objectives 1 The compiler should handle inter-node communication, not the programmer 2 The task extensions should be integrated into an existing parallel programming language, so that existing programs can benefit from task parallelism, existing libraries can be used, and the users do not have to learn a new language and 3 Current compiler technology should be able to produce efficient parallel programs that are competitive with hand parallelized codes.
