| 12 | | QCG BES/AR (the successor of the OpenDSP project) is an open architecture implementation of SOAP Web service for multi-user access and policy-based job control routines by various queuing and batch systems managing local computational resources. This key service is using Distributed Resource Management Application API (DRMAA) to communicate with the underlying queuing systems. QCG BES/AR has been designed to support a variety of plugins and modules for external communication as well as to handle a large number of concurrent requests from external clients and services. Consequently, it can be used and integrated with various authentication, authorization and accounting services or to extend capabilities of existing e-infrastructures based on Unicore, gLite, Globus Toolkit, and others. QCG BES/AR service is compliant with the OGF HPC Basic Profile specification, which serves as a profile over Open Grid Forum standards like JSDL and OGSA Basic Execution Service. In addition, it offers remote interfaces for advance reservation management, and supports basic file transfer mechanisms. QCG BES/AR was successfully tested with the following queuing systems: Sun Grid Engine (SGE), Platform LSF, !Torque/Maui, PBS Pro, Condor, Apple !XGrid and !LoadLeveler. Therefore, as a crucial component in !QosCosGrid, it can be easily set up on the majority of computing clusters and supercomputers running the aforementioned queuing systems. Currently, advance reservation capabilities in QCG BES/AR are exposed for SGE, Platform LSF and Maui (a scheduler that is typically used in conjunction with Torque). Moreover, generic extensions for advance reservation have been proposed for the next DRMAA standard release. |
