Performance Modeling and Measurements of Real Time Multiprocessors with Time-Shared Buses
February 1988 (vol. 37 no. 2)
pp. 214-224
A closed queueing network model is constructed to address workload effects on computer performance for a highly reliable unibus multiprocessor used in real-time control. The model consists of multiserver nodes and a nonpreemptive priority queue. Use of this model requires partitioning the workload into task classes. The time-average steady-state solution of the queuing model directly produces u
