Fortran-S: A Fortran interface for shared virtual memory architectures

A programming environment for distributed memory parallel computers, consisting of a Fortran 77 compiler enhanced with directives to specify parallelism, is introduced. These directives are used to specify shared data structures and parallel loops. Shared data structures are implemented using the KOAN shared virtual memory that is available on an Intel iPSC/2 computer. Preliminary results obtained with the first prototype of the compiler are presented.
