I o THE W S 360 EVALUATION PROGRAMFOR COMMUNICATIONSSYSTEMS C by G~ Greenbergo A Review by Warren Po Burrell Go Greenberg discussed this simulation model used by Worldwide Computer Services, Inco of Port Chester, New York, to provide users of 360 models 30, 40~ 50~ 65~ and 75 with the following services: * * * Proper selection of IBM hardware, before order (plus possible specials) Guidance for programming implementation~ regarding message handling. System tune up for peak performance. Planning future requirements and procedures The model encompasses OS (with Pi, P2, P3 and P4 partitions) or DOS (~Jlh Fi~ F2 and BG partitions) communications systems run with programs written in basic or queued telecommunications access macros (BTAM, QTAM). COEV input from a user employs a questionnaire for configuration (hardware and software) and load definitions Source cards are used to input and modify client application programs; with application code via PREP and flow charted activity compressed to the times taken rather than what is being done Output for management report is a print out of various statistics for run concerning resource utilization~ traffic, response and the like. An available handout exhibit depicts the form of input and output and other
