Executive Summary

Modern Object oriented programming languages provide the facility of multithreading programming which provides concurrent execution of multiple threads within the same program. Basically, threads provide a way to execute code in parallel within the same program. In high performance computing today, the multi-core CPUs have become more common in nearly all computer systems. These processors have multiple execution cores on a single physical chip. They provide parallelism between instructions and operations. Therefore, the performance measurement of multithreaded programs on these processors is an important aspect. In the present paper, the detailed architectural modeling of a Dual Core processor is done by the use of well known modeling language i.e. the Unified Modeling Language (UML). The UML design for thread execution is also done.
