QCG-Computing

QCG-Computing (formerly known as  Smoa Computing) 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 in QosCosGrid is using Distributed Resource Management Application API (DRMAA) to communicate with the underlying queuing systems. QCG-Computing 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. QCG-Computing 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-Computing was successfully tested with the following queuing systems:

  • Grid Engine,
  • Platform LSF,
  • Torque/Maui,
  • PBS Pro,
  • Condor,
  • Apple XGrid,
  • SLURM,
  • LoadLeveler.

Therefore, as a primary computing element of  QosCosGrid stack, 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-Computing are exposed for SGE, Platform LSF, Maui/Moab (a scheduler that is typically used in conjunction with Torque) and PBS Professional. Moreover, generic extensions for advance reservation have become a part of the DRMAA 2.0 standard release.
