> > | Starting with version 2.5 of the package dynsched-generic, the dynamic scheduler makes use of a simple collection of job statistics in order to calculate the Estimated Response Time (ERT) and the Worst Response Time (WRT). Statistics are stored in readable text files in a temporary directory, usually /var/tmp/info-dynamic-scheduler-generic, one file per batch system queue. The dynamic scheduler registers an event, consisting on timestamp, job id and elapsed time, for any job submitted; the information provider keeps a maximum number of events for each queue, removing the oldest ones in a round robin schema. The maximum number of events registered into a file can be configured, see below. The files for statistics are created dynamically by the information provider; they can be also removed dynamically if the corresponding queue is not enabled. Since the information provider runs with no root privileges, the directory containing the collection of statistics must have the correct ownership and access attributes. | |||||||
