The StarLight Consortium provides support for the Open Science Grid, which is operated by the OSG Consortium and is dedicated to the advancement of open science via the practice of distributed High Throughput Computing, and the advancement of its state of the art. High-throughput computing (HTC) is the execution of computational work in the form of numerous, self-contained tasks to optimize their overall completion across available computing resources. Specialized by the OSG, distributed high-throughput computing (dHTC) involves the operation of HTC-optimized infrastructure across many independent, collaborating administrative domains. The OSG provides various open-source software, other technologies, and services for researchers and research organizations to support their dHTC compute requirements. OSG software and technologies allow research organizations to build dHTC systems at-scale from shared computing and data resources, and to make these resources available to researchers within virtual clusters (“pools”).

Some pools or participating organizations provide application-specific interfaces or datasets, such that researchers may not even be aware of integration with OSG and its services/technologies. Many OSG technologies and services are based upon or directly leverage the HTCondor Software Suite (HTCSS), in addition to other open-source tools that enable shared computing and data capabilities. These can be deployed by a research organization to create their own dHTC pool across participating compute and data components, making their federated capacity available to the researchers they serve.
