We are pleased to announce the fourth Frontera Pathways and Frontera Large Scale Community Partnership (LSCP) allocation tracks will remain open through November 20. Resources available for request include Frontera and its GPU subsystem, as well as the Longhorn GPU resource. Pathways These are small allocations (between 10,000-250,000 SUs per year) to science teams with a strong scientific justification for access to a leadership-class computing resource, but who have not yet demonstrated code readiness to effectively utilize such a resource. LSCP These are allocations (between 25,000-1,000,000 SUs per year, up to 3 years) where we can’t strictly characterize the set of experiments to run within a 12-month allocation period, but that line up with a large team or community, a large instrument, or other large NSF investment. Detailed descriptions of all four Frontera allocation tracks can be found on the Frontera Allocations web page. How to Submit an Allocation Request Please begin by reading the Allocations Policy & Submission Guidelines that provides information regarding who is eligible to apply, minimum and maximum allocation sizes, and an outline of the information that is required to be included in your proposal. After reading the allocations policy and guidelines, you may determine that a startup allocation would be beneficial to do code performance and benchmarking to be incorporated into your Pathways or LSCP proposal. Instructions for obtaining a Startup allocation are included on the policy & guidelines web page. Please submit any questions you may have through the TACC Consulting System or feedback form. https://portal.tacc.utexas.edu/tacc-consulting https://portal.tacc.utexas.edu/feedback Thanks, Tim Cockerill Director of User Services Texas Advanced Computing Center The University of Texas at Austin
