Job schedul in Grid batch farms
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.
Feasibility of pump speed control analyzed; control method selection compared. Discussion given on the necessity of wide spread application in coal preparation plants of variable frequency speed control technology, its development and main field of application. Pointed out were the problems to be considered on appliances selection and operation. Its application at Matou Coal Preparation Plant is taken as an example to explain the economic benefit thereof.
