Glenda: an environment for easy parallel programming

Introduces a software package called “Glenda”, designed to support easy parallel programming. Glenda implements a coordination language based on a global “tuple space”. This coordination language consists of seven operations to output and input tuples from within participating programs. Glenda communications are performed using PVM (Parallel Virtual Machine) message passing functions. The Glenda package consists of a preprocessor to add the coordination operations to the C programming language, a set of communication functions and a tuple server process. We show the utility of Glenda based on an underwater acoustic modeling benchmark
