Abstract : We compare the writing and execution of programs written in Cosmic Cube C with programs written in the graphical parallel programming environment and language Poker. Our example programs, an implementation of a Cholesky algorithm for a banded matrix, were written in both languages and compiled into object codes that ran on the Cosmic Cube. However the program written in Poker is shorter, faster and easier to write, easier to debug, and portable without changes to other parallel computer architectures. The Poker program was slower than the program written directly in Cosmic Cube C, however the experiments provided insights into changes that make Poker programs nearly as fast. Keywords: High level languages, Low level languages.
