     53=== QCG-Coordinator === 
     54QCG-Coordinator is used to the spawning of parallel application processes on co-allocated computational resources. Since the standard methodologies used in MPI or ProActive allow to run jobs only on a single machine, it was needed to implement additional entity to support multi-cluster runs.

    5358=== Data Movement === 
    5459As many other e-infrastructures controlled by middleware services, !QosCosGrid takes advantage of the GridFTP protocol for large data transfer operations, in particular to stage in and stage out files for advanced simulations. GridFTP is a high-performance, secure, reliable data transfer protocol optimized for high-bandwidth wide area networks. It is a de facto standard for all data transfers in grid and cloud environments and extends the standard FTP protocol with functions such as third-party transfer, parallel and striped data transfer, self-tuning capabilities, X509 proxy certificate-based security, support for reliable and restartable data transfers. The development of GridFTP is coordinated by the GridFTP Working Group under the hood of the Open Grid Forum community.
