A shared memory multi-core computer system is a computing paradigm in which processors have more than one core to process requests and also have access to a common memory. Most existing works are limited to modeling of a shared memory single-core computer system and thus the models are not flexible enough to study the operations of multi-core computer systems. Hence, in this paper, a high-level Petri Nets formalism (Timed Coloured Petri Nets) was used to develop a simulation model for a shared memory multicore computer system. Intel HP core i5 was used as a case study in developing the TCPN model for a shared memory multi-core computer system. The developed TCPN model was simulated using Coloured Petri Net (CPN) tools. One hundred and fifty simulation runs were carried out in order to obtain average utilization rate of the shared memory and average waiting time of the processor's cores in accessing the shared memory. The developed TCPN model was validated based on both real and simulated average memory utilization of the shared memory multi-core computer system. The validation result of the developed TCPN model showed that there was no significant difference between the simulated and real average memory utilization of the shared memory multi-core computer system.
