Job scheduling in Grid batch farms

摘要

We present here a study for a scheduler which cooperates with the queueing system TORQUE and is tailored to the needs of a HEP-dominated large Grid site with around 10000 jobs slots.Triggered by severe scaling problems of MAUI, a scheduler, referred to as MYSCHED, was developed and put into operation.We discuss conceptional aspects as well as experiences after almost two years of running.
