Abstract:

The paper describes preliminary investigations concerned with workload determination and representation for on-line computer systems. Workloads are described in terms of the work required by users at terminals instead of demands on system resources, thereby avoiding biases due to the specific machine under investigation. Prominent users are identified by accounting data, and their on-line requirements are determined by trace programs, source code frequency counts, and various analytical techniques. Complete on-line test workloads can be described by a set of terminal sessions which are then simulated using the Remote-Terminal Emulator. Experimental work on the MITRE IBM 370155 is described, and it indicates that actual terminal sessions can be represented by synthetic sessions, thus minimizing the problem of developing and debugging test workloads for each new application.
