Tank monitor and control system (TMACS) performance analysis - under steady-state conditions

PDF Version Also Available for Download.

Description

A means to predict the performance impacts to the TMACS computer system prior to further increases in the TMACS point configuration is studied. A series of CPU utilization measurements are made on the TMACS production and development computers. These measurements are under steady-state operating conditions for I/O point processing and remote terminal support.The data from these measurements are used to derive formulas that are then used to project CPU utilization for other configuration profiles. A configuration profile is described for (1) the current TMACS production system, (2) the maximum capacity of the current TMACS production system, and (3) a much ... continued below

Description

A means to predict the performance impacts to the TMACS computer system prior to further increases in the TMACS point configuration is studied. A series of CPU utilization measurements are made on the TMACS production and development computers. These measurements are under steady-state operating conditions for I/O point processing and remote terminal support.The data from these measurements are used to derive formulas that are then used to project CPU utilization for other configuration profiles. A configuration profile is described for (1) the current TMACS production system, (2) the maximum capacity of the current TMACS production system, and (3) a much larger target system, which reflects the anticipated size of the monitoring system for the upgrade project, W-314. The derived formulas are used to calculate CPU utilization for each of these configuration profiles. The formulas are validated by comparing the calculated with the measured results for the current production configuration. An analysis is performed that shows that the current system of 1.600 points can be expanded to 4,000 points without any changes. Furthermore, the current system can be expanded to 10,000 points to meet the requirements of the target system with the planned purchase of new-generation hardware and modifications to the logging and delta-check routines.
