The production environment has been switched from a commercial<br />batch system PBSPro, which was replaced by an open source alternative Torque<br />batch system.<br />This paper concentrates on two aspects of this transition. First, we will present<br />our practical experience with Torque being used as a production ready batch<br />system. Our modified version of Torque, with all the necessary PBSPro ex-<br />clusive features re-implemented and further extended with new features like<br />cloud-like behaviour, was deployed across the entire production environment,<br />covering the entire Czech Republic for almost a full year.<br />In the second part, we will present our work on meta-scheduling. This in-<br />volves our work on distributed architecture and cloud-grid convergence. The<br />distributed architecture was designed to overcome the limitations of a central<br />server setup, which was originally used and presented stability and performance<br />issues. While this paper does not discuss the inclusion of cloud interfaces into<br />grids, it does present the dynamic infrastructure, which is a requirement for<br />sharing the grid infrastructure between a batch system and a cloud gateway.<br />We are also inviting everyone to try out our fork of the Torque batch system,<br />which is now publicly available.<br /><br />}, number={2}, journal={Computer Science}, author={Toth, Simon and Ruda, Miroslav}, year={2012}, month={Dec.}, pages={33} }
