Once installed, Add a new VPN connection with a server address ‘vpn.unt.edu’ or ‘vpn2.unt.edu’.
Now turn on the AnyConnect VPN and log in with your UNT AMS EUID and password (not the same as your Talon password).
Make sure your VPN status is in connected state:
iPhone: Under Setting, VPN, make sure the ‘Status’ says ‘Connected’.
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:
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:
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:
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
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 firstname.lastname@example.org 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.
