The Performance of the Czech National Grid Infrastructure after Major Reconfiguration of Job Scheduling System

Popis výsledku v původním jazyce

This work describes the outcomes of a large reconfiguration of the job scheduling system used in the Czech National Grid MetaCentrum which has been done in January and July 2014. MetaCentrum serves to various users and research groups. It is very important to guarantee that computational resources are used efficiently and in a fair fashion with respect to different users. With the significant growth of MetaCentrum (1,500 CPU cores in 2009 vs. 10,000 CPU cores in 2014) we recently had to revise our scheduling approaches to better reflect the increased size of the system and the growing heterogeneity of hardware resources and users' workloads. This revision took place in three major steps through the year 2014. First of all, new multi-resource aware fair-sharing algorithm was deployed, in order to improve fairness with respect to growing heterogeneity of resources and users demands. Second, large queue reconfiguration was done, in order to decrease resource fragmentation and improve util
