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)
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)
Storage systems in current day computing machines are in a variety of forms: registers, caches, main memory, disks, tapes, network storage systems, and so on. Each storage system provides the basic functions of storing data and holding the data until it is retrieved at a later time. The main differences between the various storage systems are their speed,(More)
