Analysis and Clustering of Workload in Google Cluster Trace Based on Resource Usage

摘要

Cloud computing has gained interest amongst commercial organizations, research communities, developers and other individuals during the past few years. In order to move ahead with research in field of data management and to enable processing of such data, we need benchmark datasets and freely available data which are publicly accessible. Google in May 2011 released a trace of a cluster of 11k machines referred as "Google Cluster Trace". This trace contains cell information of about 29 days. This paper provides analysis of resource usage and requirements in this trace and is an attempt to give an insight about such kind of production trace similar to the ones in cloud environment. The major contributions of this paper include statistical profile of jobs based on resource usage, clustering of workload patterns and classification of jobs into different types based on k-means clustering. Though there have been earlier works for analysis of this trace, but our analysis provides several new findings such as jobs in a production trace are trimodal and there occurs symmetry in the tasks within a long job type.
