In this paper we model the hierarchal nature of memory in order to examine the variance, and in general, all moments of the distribution of time memory access. The existence of an unbounded variance for the memory access time can lead to extremely long wait queues and a particular class of distributions that has this property is the power tailed(More)
As the modern computing environment expands memory hierarchy from CPU registers and local memory to network storage, the optimal goal of a computer architect becomes to design a memory hierarchy that maximizes the overall design of his machine with a minimal cost. This requires deciding on the number, speed and size of the hierarchical layers. As the gap(More)
Real-time resource scheduling is an important factor for improving the performance of cluster computing. In many distributed and parallel processing systems, particularly real-time systems, it is desirable and more efficient for jobs to finish as close to a target time as possible. This work models the execution time for such a stochastic environment and(More)
In modern computing environment, memory hierarchy expands from CPU registers, high speed caches and local memory to middle-tier, network storage, web cashing, internet storage, and active networks. As the gap between processor and memory speed is growing exponentially, it becomes more important to develop an analytical model to capture all these(More)
