Lonestar6 currently has a temporary outage affecting Corral (/corral). Regular queues will remain open but jobs that attempt IO to that resource will fail. Setting jobs to "hold" (scontrol hold [JOBID] ; scontrol release [JOBID]) until we're able to restore access to the corral filesystem would preserve your place in queue for any jobs needing /corral to run.

Next Friday: OpenMP for C++
Friday 02/10/23, 9:00 AM - 1:00 PM CST 
C++ programmers have always been able to the C interface to OpenMP. In this tutorial we will discuss a number of ways that the power of C++ makes expressing algorithms in OpenMP more elegant. We will discuss: 
- range based loops and custom iterators; 
- user-defined reductions, with such applications as binning and filtering; 
- a variety of smaller topics.

Frontera Emergency Maintenance February 1 2023

Posted by Mark Brueschke on Feb 1, 2023 4:38:27 PM

Due to power issues from the ice storm, Frontera will be unavailable until power is restored and stable.

We will post an update once full service is restored.

Updated on Feb 2, 2023 4:42:39 PM

The power situation in Austin has stabilized some, but about 30% of the city is without power still.   For now, we've opened up the development, small, nvdimm and rtx queues along with half of the normal compute nodes.  We anticipate restoring the other half of the compute nodes once the power grid in Austin has improved, hopefully some time tomorrow.

Lonestar6 scratch file system usage has steadily increased over the production life of the system and has now reached thresholds for active maintenance (near 90%).

We request that all users remove any unused, old, and duplicate data from their scratch directory as soon as possible. We would also like to remind users to read the policies on /scratch usage in the user guide and keep in mind that offering filesystems with no quotas will always require active clean-up. We're hoping for assistance from the Ls6 user community with that clean-up.
 
If a significant reduction of data is not observed over the coming days, we will proceed to remove old data on behalf of users. Please also note that actively attempting to avoid the purge processes is behavior that will be monitored for, is extremely unfair on other Ls6 users, and will result in account suspension.
 
We thank you in advance for your understanding and thank you to all users who are pro-actively managing their data usage.

After three years in production, Longhorn is being retired at TACC and will be unavailable after Monday November 28 2022.


The Longhorn queues will close for the final time at 9:00 AM (CST) on Thursday, November 24 2022. No jobs will be accepted that run past that date and time.
Login nodes will remain available for data transfers through Monday, November 28 2022.
All system access will be disabled beginning on Tuesday, November 29 2022.
 
All TACC users with allocations on Longhorn are eligible to transfer to either Lonestar6 or Frontera. TACC staff are available to help with transitioning both allocations and workflows. Please submit a consulting ticket with the subject "Longhorn Transition" for more information about requesting allocations on Lonestar6 or Frontera.
 
In preparation for retirement, TACC staff have already made an administrative backup of data on Longhorn’s home and scratch filesystems on November 18 2022. Any data created after that date will not have been included in the backups. To access your data, please open a consulting ticket. These backups will only be available until February 28 2023 - please reach out for assistance as soon as possible.
 
If you need to back up additional data that has not been captured by the administrative backup (i.e. data that has been generated since November 18 2022), please refer to the Longhorn User Guide section on rsync. 
 
If you have any questions or concerns about the transition please reach out to us here:
