All activities of the Frontera project support the overriding project goal of serving "as a national resource for providing predictable and sustained long-term leadership computing capabilities for science and engineering to push the frontiers of knowledge...". In the context of Frontera, we believe this means enabling computation-based scientific discovery, with a particular focus on "big science." At least 80% of the capacity of Frontera, or about 55 million node hours, will be made available to scientists and engineers around the country.
In general, proposers must show compelling science or engineering challenges that require multi-petascale computing resources, and they must be prepared to demonstrate that they can effectively exploit the multi-petascale computing capabilities offered by Frontera. Proposals from or including junior researchers are encouraged, as one of the goals of this solicitation is to build a community capable of using petascale computing. The Frontera team will offer consulting support and assistance to each project team that is granted access through this solicitation.
Described below, we offer four allocation tracks to accommodate a range of research needs for large-scale discovery science. As proposal submission windows become available, we will post those opportunities on this web page.
For more information on the Allocations process via the National Science Foundation, please review the Dear Colleague Letter: Frontera Leadership-Class Computing Allocations.
Leadership Resource Allocation (LRAC) – Large allocations to science teams with a strong scientific justification for access to a leadership-class computing resource to enable research that would otherwise not be possible. Successful applicants must demonstrate readiness to use the allocated cycles, as well as current peer-reviewed research funding to support the activities conducted on Frontera. LRAC submission deadlines will be at least once per year, possibly twice depending on availability of compute time.
Pathways – Small allocations 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. Successful applicants will use the allocation award to work with the Frontera team to scale their codes in order to effectively use the system. Successful applicants must demonstrate existing research funding to support the required code and algorithm development activities on Frontera. Additionally, early career scientists and engineers with an outstanding publication record investigating novel techniques for solving potentially transformative S&E research topics are encouraged to apply. Pathways submission deadlines will be quarterly.
Large-Scale Community Partnerships (LSCP) – Extended allocations of up to three years to support long-lived S&E experiments. Successful applicants must demonstrate current peer-reviewed research funding to support the activities conducted on Frontera for the time period requested. The LSCP process will make merit-based allocation awards annually for allocations spanning three years, with years 2 and 3 awarded after successful completion of a progress review.
Director Discretionary Allocations (DD) – Allocations for projects that don’t fit well into the three tracks described above, such as: areas of urgent need, educational usage, and industrial collaborations/research. Submissions will be accepted on a rolling basis.
Additionally, users may request archive space for their data on TACC’s tape storage system.
Archival Storage (Ranch) – Ranch is TACC’s tape archive storage system. Ranch recently underwent upgrades which, among other things, dramatically increased the disk cache of the archive to approximately 30PB. This enables all archive data that has been used in recent months to remain on disk, and to keep small files on disk for up to several years if occasionally being re-used. Behind the disk storage are multiple tape libraries with capacity scalable to an exabyte or more. One of the tape options will offer encryption and appropriate compliance to store controlled unclassified information. (If CUI data is required, users should specify this in the allocation request.)
For questions about allocations, please submit a ticket via the TACC Ticket System, and select Other in the System/Resource dropdown menu.
