HPC Community,
We are excited that we are close to launching Talon3! A select group of users is currently beta testing the new cluster. We anticipate launching Talon3 early next week pending feedback from testing. As such I wanted to ensure you were aware of a few items:
Research Community,
We are in the process of porting Scientific Software packages to Talon3. To help us prioritize installations, please take a moment to view the 10 most used packages:
Hi HPC Community,
Talon2 is back online and compute services have been resumed. All jobs that were suspended appear to have resumed correctly. As always, please notify us immediately if anything looks out of place.
Please note that we are still solving the Lustre Metadata high-availability issue. Lustre is extremely robust but this issue could cause loss of redundancy. However, we feel the risk of this is low enough that we can safely resume service.
A few more updates:
Research Community,
Good news and not so good news.. Good news:
We have completed the required maintenance and can see all compute nodes connected in the new fabric. We are essentially ready to restore service.
Not so good news:
Hi,
In regards to the scheduled maintenance.. Unfortunately we encountered a few unforeseen issues that set us back yesterday. However, we are about 80% complete with the work needed in order to restore services. We are fairly confident that Talon2 will be back online this afternoon/evening. Please standby for updates..
To give a scope of the work already accomplished:
- > 200 fiber cables were individually prepared and labeled
- > 100 fiber cables had to be untangled, sorted, and tested
Research Community,
Momentarily we will begin maintenance on the Infiniband infrastructure that you were notified of last Tuesday. The maintenance is required in order to finalize the upgrade to Talon3. Therefore, shortly Talon2 (talon2.acs.unt.edu) will temporarily taken offline to perform the maintenance. Compute services will be unavailable until Wednesday afternoon January 25, 2017.
As always, please message hpc-admin@unt.edu if you have any concerns or questions.
HPC Research Community,
Next Monday January 23, 2017, we plan to perform crucial maintenance on the Infiniband infrastructure that supports high speed communication on Talon2. The maintenance is required in order to finalize the upgrade to Talon3. Unfortunately Talon2 and it's Infiniband network must be temporarily taken offline to perform the maintenance. Compute services will be unavailable from Monday morning on January 23, 2017 until Wednesday afternoon January 25, 2017.
HPC Community,
UIT HPC Services is in the final stages of preparing to upgrade the Talon 2.0 HPC system to Talon 3.0. This upgrade will result in additional computational capacity while minimizing, as much as possible, complete interruption of HPC service. However, during the next two months of November and December, expect operations to continue with degraded compute capacity. This will likely increase queue wait times for submitted jobs.

The UNT HPC team has deployed another high-speed parallel filesystem affectionately named scratch2. It is running Lustre 2.5.2 on a DDN SFA7700X storage appliance. The SFA7700X is a hybrid flash storage appliance, purpose-built for Big Data requirements that enables our researchers to continue solving bigger problems. This filesystem has 1.4PB total available and can sustain speeds of up to 10GB/s over FDR Infiniband. For more info see: http://www.ddn.com/products/lustre-file-system-exascaler/
