PCF programming model and FORTRAN bindings

Summary form only given. A progress report on the standardization activity of the Parallel Computing Forum, including the programming model and the binding of that model in FORTRAN-77, is presented. The programming model defines two methods of describing the work to be executed in parallel: iterations of a loop and single-entry multiple-exit sections of code. Nested parallelism is supported, along with a partial sharing model for programming language viewable objects. Access to shared objects is controlled by both explicit and implicit synchronization. A large collection of details ranging from input/output issues to sequential consistency and to language/machine atomicity mismatch are addressed
