The extension of TORQUE scheduler allowing the use of planning and optimization in grids

Chlumsky V., Klusacek D., Ruda M.

Vol. 13 (2)

5-19

In this work we present a major extension of the open source TORQUE Resource Manager system. We have replaced a naive scheduler provided in the TORQUE distribution with complex scheduling system that allows to plan job execution ahead and predict the behavior of the system. It is based on the application of job schedule, which represents the jobs’ execution plan. Such a functionality is very useful as the plan can be used by the users to see when and where their jobs will be executed. Moreover, created plans can be easily evaluated in order to identify possible inefficiencies. Then, repair actions can be taken immediately and the inefficiencies can be fixed, producing better schedules with respect to considered criteria.

Practical experiences with Torque meta-scheduling in the Czech National Grid

Toth S., Ruda M.

Vol. 13 (2)

The Czech National Grid Infrastructure went through a complex transition in the last year. The production environment has been switched from a commercial batch system PBSPro, which was replaced by an open source alternative Torque batch system. This paper concentrates on two aspects of this transition. First, we will present our practical experience with Torque being used as a production ready batch system. Our modified version of Torque, with all the necessary PBSPro exclusive features re-implemented and further extended with new features like cloud-like behaviour, was deployed across the entire production environment, covering the entire Czech Republic for almost a full year. In the second part, we will present our work on meta-scheduling. This involves our work on distributed architecture and cloud-grid convergence. The distributed architecture was designed to overcome the limitations of a central server setup, which was originally used and presented stability and performance issues. While this paper does not discuss the inclusion of cloud interfaces into grids, it does present the dynamic infrastructure, which is a requirement for sharing the grid infrastructure between a batch system and a cloud gateway. We are also inviting everyone to try out our fork of the Torque batch system, which is now publicly available.
