Users often behave speculatively, submitting work that initially they do not know is needed. Farm computing often consists of single node speculative tasks issued by, e.g., bioinf...
It is common to evaluate scheduling policies based on their mean response times. Another important, but sometimes opposing, performance metric is a scheduling policy’s fairness....
Sleeping is an important method to reduce energy consumption in many information and communication systems. In this paper we focus on a typical server under dynamic load, where en...
