REAL WORKLOAD CHARACTERIZATION AND SYNTHETIC WORKLOAD GENERATION

Keerthi Bangari, Chittipothula C Y Rao

Abstract: In computing, the workload is the amount of processing that the computer has been given to do at a given time. Workloads are two types namely synthetic and real workload. Real workloads are not publicly available and some workloads are available in the internet like Google trace, world cup 98 trace and Clark Net trace. Synthetic workloads are generated based on our experiments. The real trace is downloaded from Google cluster data which consists of two workloads. In first trace it refers to 7 hours period with set of tasks. In second trace it refers to 30 days period of work. Each dataset is packed as set of one or more files, each provided in compressed Common Separated Values(CSV) format. In this paper we are analyzing the Google cluster data version 2 trace in IBM SPSS statistics and generating another workload called synthetic workload with the same characteristics and behavior of real workload based on formulae which is generated using linear regression in IBM SPSS statistics.
