A hybrid approach for the modelling and simulation of a virtually shared memory parallel computer architecture

Modelling and simulation have been assigned crucial roles in the design, de velopment, analysis and evaluation of computer architectures. The design of parallel architectures in particular is a complex and difficult endeavour that makes modelling and simulation essential tools. In this case, high sim ulation performance is a prerequisite since, large workloads need to be sim ulated for a realistic analysis of the parallel system. This paper presents the approach that has been followed for the modelling and simulation of Pi SMA, a virtual shared memory parallel architecture, scaleable up to 100 s o f processors.
