Questionnaire for user habits of compute clusters (QUHCC)

Abstract

There is an increased interest to improve existing schedulers of compute clusters. Trace data are used to analyze the performance of compute clusters and to develop improved algorithms, but the interaction of the user and the compute cluster is not considered yet. Therefore, the current study investigates user behavior and satisfaction with regard to compute clusters. The resulting data are used to model users and to run a scheduler simulation with these modeled users. A new questionnaire for User Habits of Compute Clusters (QUHCC) with 7 scales and 53 questions was developed for this purpose. Results indicate that there is considerable potential to improve the performance of computer systems, viz. users satisfaction is limited, because different kinds of user strategies are necessary to improve the performance of the system. Future work includes the further validation and improvement of the questionnaire.
