A Statistic Analysis of Nqs Parameter Effectiveness for the Resource Usage in the System

The use of PC cluster systems composed of many PCs is largely spread in these days. It is important to improve system usage keeping proper fair-share policy. Job scheduling is a function that dynamically allocates submitted jobs to hardware resource in user program execution units. This optimization problem is difficult to solve because many parameter are connected. In scheduler software, there are many parameters and the effectiveness of many parameters is related with each other complicatedly. Therefore it is more difficult to find optimal parameter configuration to improve the system usage efficiency. So in this paper, we performed various analyses of those parameters and report the results. Keyword: NQS, Job scheduler, Simulator, Correlation, ANOVA, PC clusters parameter, Optimization
