Frontera will be reserved for Texascale Days - very large scale runs of at least half system size (3,700 - 4,000 nodes) or full system size (7600 - 7900 nodes) Monday, February 2 through Monday, February 8. This event allows our researchers the opportunity to work on problems that may not be...

Frontera will be reserved for Texascale Days - very large scale runs of at least half system size (3,700 - 4,000 nodes) or full system size (7600 - 7900 nodes) Monday, February 2 through Monday, February 8. This event allows our researchers the opportunity to work on problems that may not be possible at the smaller scale. To be eligible to participate, your application must have already successfully run on at least 2,048 nodes in the “large” Queue on Frontera.  For access to the “large” queue, please submit a ticket with scaling data.

On the last day, Feb. 8, 2 hour blocks will be available for benchmarking efforts rather than production runs.  The other days, February 2 - February 7, will be set aside for production runs.  On these days, each project will have dedicated access to the number of nodes requested for a 24 hour period starting at 0900 CST.

To participate, please fill out and submit the form (https://forms.gle/oeTiBL9hPW6UyGZm9) before COB January 22.

This should include your own strong or weak scaling results from Frontera on up to 512 nodes.If you have already run in the large queue on at least 2,048 nodes, you are qualified to request a Texascale reservation for running at 3,800 nodes or more.

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.

The failed controller on /scratch3 continues to be worked on and DDN is investigating, but it might be offline until tomorrow. For now, we have cancelled all running jobs using /scratch3 and held pending jobs running out of /scratch3 to prevent them from failing. The queues have been re-opened for those users running out of /scratch1 or /scratch2. Users of /scratch3 should avoid submitting new jobs until the filesystem access has been restored.

Frontera will be reserved for Texascale Days - very large scale runs of at least 4,000 nodes up to full system - to be held immediately following the system maintenance September 1 through Monday September 7. This event allows our researchers the opportunity to work on problems that may not be possible at the smaller scale. To be eligible to participate, your application must have already successfully run on at least 2,048 nodes in the Large Queue on Frontera.If you would like to participate in Texascale Days, please submit a ticket and include a brief description of the experiment you would like to run and how many nodes would be required.  If you have not yet run at 2,048 nodes and would like to request access to the large queue, include this in your request. This should include your own strong or weak scaling results from Frontera on up to 512 nodes.If you have already run in the large queue on at least 2048 nodes, you are qualified to request a Texascale reservation to try running at 4,000 nodes or more.
