Abstract
We have conducted a performance analysis of a large scale multiprocessor system based on shared buses organized in a hierarchical fashion and employing an easy to implement snoopy cache protocol. · This arrangement, named TREEBUS [ 5], presents a logical extension path for multiprocessor systems based on a single shared bus whose scalability is limited by the available system bus bandwidth [26]. The multiple, independent, hierarchical buses overcome the bus bandwidth limitation and the architecture can scale to relatively large sizes. We have developed an easy to use, reasonably accurate and computationally efficient analytic model for analyzing the performance of the memory hierarchy. Our analysis presents a balanced view by incorporating cost and size of the memory subsystem, two parameters which can significantly impact the feasibility of this architecture. The results indicate that the TREEBUS can deliver high performance for a maximum of about 512 processors using available technology. For larger sizes, the problem is not the limited system bus bandwidth but the unmanageable size of the main memory and a deteriorating cost/performance ratio.
