Quantification of Heterogeneity in Distributed Computing Systems
Heterogeneity is an indispensable part of modern distributed computing systems and considering it in devising system solutions (e.g., resource allocation) is decisive to optimize the system performance objective (e.g., QoS, incurred cost, and energy consumption). Even though system heterogeneity has been extensively studied in the past, there is yet to be a concrete study on measuring the impact of level of heterogeneity on the system performance objective. For that purpose, we require a measure that can quantify the system heterogeneity with respect to its impact on the performance, thereby, making the system comparable against others. Accordingly, our goal in this study is to develop a “performance-driven heterogeneity measure” that can characterize the impact of heterogeneity level of a system on its performance behavior (a.k.a. QoS) in terms of percentage of tasks meeting their deadlines.
