The Technology Investigation Service (TIS) award within XSEDE is a five-year project supported by the National Science Foundation (NSF).

The TIS team includes the National Center for Supercomputing Applications (NCSA), the Texas Advanced Computing Center (TACC), the Pittsburgh Supercomputing Center (PSC), and the National Institute for Computational Sciences (NICS) and is led by principal investigator John Towns (NCSA). Co-principal investigators are Maytal Dahan (TACC), J Ray Scott (PSC), and Victor Hazlewood (NICS).

TIS is responsible for identifying and tracking hardware and software technologies that can enable XSEDE to improve its operations, capabilities, and user impact.  A subset of the identified technologies is selected for evaluation by the TIS team.  The team focuses on technologies that offer new capabilities presented by technology opportunities and stimulated by emerging science challenges.  Results of the evaluations are made publically available through the XSEDE TIS website.  These results will be useful to a much broader audience of cyberinfrastructure users, developers and providers outside the XSEDE context. 

To accomplish this mission, TIS is comprised of two teams.

The Technology Identification and Tracking team develops and maintains the XSEDE Software Search and the Technology Investigation Service web pages.

To view the evaluations that have been completed and review the technologies under consideration please visit the Technology Evaluations page.

The Technology Evaluation Process (TEP) team conducts evaluations of technologies and produces reports describing their findings.  This team works closely with the XSEDE Architecture & Design group as well as the XSEDE User Engagement team to determine appropriate technologies for evaluations.  Input from developers and scientists outside XSEDE is welcome.  Evaluations are documented through the XTED website.  To perform the evaluations, the TEP team assembles system resources from dedicated TIS systems as well a community resources such as FutureGrid and XSEDE Service Providers.  A sub-team within TEP has responsibility for identifying the resources and provisioning the base software to enable the evaluations.

We encourage questions and feedback on TIS through the Feedback mechanism.
