Vienna Fortran - A Language Specification. Version 1.1
Interim rept. no. 21
INSTITUTE FOR COMPUTER APPLICATIONS IN SCIENCE AND ENGINEERING HAMPTON VA
Pagination or Media Count:
This document presents the syntax and semantics of Vienna Fortran, a machine-independent language extension to FORTRAN 77, which allows the user to write programs for distributed-memory systems using global addresses. Vienna Fortran includes high level features for specifying virtual processor structures, distributing data across sets of processors, dynamically modifying distributions, and formulating explicitly parallel loops. The language is based upon the Single-Program-Multiple-Data SPMD paradigm, which exploits the parallelism inherent in many scientific codes. A substantial subset of the language features has already been implemented.
