Abstract
THIS PROPOSAL IS FOR THE EXPLORATION OF THE FEASIABILTY OF DEVELOPING COMPUTER SYSTEM SIMULATION PROGRAMS DIRECTLY FROM GRAPHICAL REPRESENTATIONS OF SOFTWARE SYSTEMS AND COMPUTER SYSTEM RESOURCE/DEVICE CONFIGURATIONS. THE CONCEPT IS TO EXTEND AND UTILIZE A SET OF EXISTING GRAPHICAL AND DECLARATIVE REPRESENTATIONS OF COMPUTER SYSTEM EXECUTION. THIS SET APPEARS TO BE A NEARLY ADEQUATE BASIS OF REPRESENTATION, AND INCLUDES: A) THE EXECUTION-GRAPH MODEL OF SOFTWARE SYSTEM EXECUTION BEHAVIOR PROPOSED BY SMITH AND BROWNE; B) A QUEUEING NETWORK REPRESENTATION OF A COMPUTER SYSTEM THAT INCLUDES PASSIVE RESOURCES; C) INFORMATION PROCESSING GRAPHS, WHICH REPRESENT THE FLOW OF WORK BETWEEN DEVICES ON A COMPUTER SYSTEM; D) THE PAWS SIMULATION LANGUAGE, IN WHICH THE EXECUTION BEHAVIOR OF GIVEN WORKLOAD ELEMENTS ON A GIVEN RESOURCE CONFIGURATION IS SPECIFIED IN AN ENTIRELY DECLARATIVE AS OPPOSED TO PROCEDURAL FASHION. THESE REPRESENTATIVES APPEAR TO SUFFICIENTLY SIMILAR AND TO HAVE SUFFICIENTL EXPLICITLY DEFINED RELATIONSHIPS SO THE AUTOMATION OF THE TRANSFORMATION BETWEEN THE REPRESENTATIONSCAN BE ACCOMPLISHED BY STANDARD COMPILATION TRANSLATION TECHNIQUES. THE THE RESEARCH WILL BE USED TO ESTABLISH DATA BASE SCHEMA REPRESENTATIONS OF EXECUTION GRAPHS, QUEUEING NETWORK MODELS, INFORMATION PROCESSING GRAPHS AND PAWS PROGRAMS AND TO DEFINE TRANSFORMATIONS BETWEEN THESE REPRESENTATIONS THAT WILL ALLOW AUTOMATED PROGRESSION FROM THE GRAPHICAL SPECIFICATIONS OF THE HARDWARE AND SOFTWARE SYSTEMS TO A FORTRAN SIMULATION PROGRAM.
