Open Science Grid (OSG)
The Open Science Grid (OSG) facilitates access to distributed high-throughput computing (dHTC) via a partnership of national labs, universities, and other organizations who share computing capacity for use by researchers across and beyond the United States. A number of resources exist for organizations who would like to contribute local computing and data capacity and/or to coordinate it with collaborators at other institutions. Individual researchers, institutions, or multi-institutional collaborators can gain access to run work on OSG via local submission points or through the OSG Connect service (available to U.S. academic, government, and non-profit researchers).
The OSG is perhaps the most scalable resource for computational work that can be run as numerous independent jobs, making it an ideal fit for many existing and future gateways. Individual users regularly occupy thousands of CPU cores across jobs when each runs for less than a day on a single core, achieving greater parallelization than on a single cluster. Computational work runs in the OSG via the HTCondor job scheduler, which can be integrated with numerous workflow tools (Pegasus, TOIL, CCTools, HTCondor's own DAG Manager, etc.) and made interchangeable with submission to other schedulers. Available capacity includes not only the significant CPU and data storage in OSG, but also GPUs and seamless integration with cloud resources. The OSG offers multiple services in support of the Science Gateway Community, including consulting on workflow design/optimization, data handling, and software solutions via email@example.com.
