New Corral Login Node

Posted by Jason Allison on Aug 9, 2017 11:10:15 AM

The Corral login node, accessed as corral.tacc.utexas.edu or login1.corral.tacc.utexas.edu, will soon be retired and replaced with general-purpose “data transfer nodes”, all accessed through the alias data.tacc.utexas.edu. Alongside this transition, the new nodes will require the use of TACC’s multi-factor authentication tokens ( https://portal.tacc.utexas.edu/tutorials/multifactor-authentication).

This transition will allow us to better serve our user community with improved performance, reliability, scaling and security.

The new data transfer nodes are available now for testing, and provide direct access to both the Corral 3 file systems as well as the Stockyard/work file system. These nodes have all the most common file transfer facilities installed, including the iRODS client “i-Commands" and the Globus GridFTP client tools.

If you have automated transfers or otherwise perform large-scale data transfer through the current Corral login node you should test your workflows using the new data transfer nodes as soon as possible.

Note that no data migration from the /home areas of the Corral login node will be performed since those areas are not intended for any significant data storage. If you have configuration or other files stored in $HOME on corral.tacc.utexas.edu then please migrate these files to the data transfer node or another resource in a timely manner to ensure you do not lose any data.

A follow-up notification will be sent in the coming weeks announcing the retirement date for the current Corral login node. Please ensure that you have tested any workflows relying on the current Corral login node with the new infrastructure prior to the final shutdown date.

Please submit any questions you may have via the TACC User Portal.

Updated on Aug 1, 2017 8:07:50 PM

LS5 has been returned to production. We apologize for the delay. Unfortunately the rsip service error was not resolvable within a reasonable time-frame and so the rsip errors persist. This means that some compute nodes are still unable to access outside IP addresses. We are able to make some changes towards resolving this while the system is running so please watch user news for updates to this service

Updated on Aug 1, 2017 5:08:32 PM

LS5 is still experiencing issues relating to the rsip server setup. We estimate that this can be solved within a reasonable amount of time and so are extending the LS5 until 23:00.

Stampede 2 Update: Stampede 1’s Production KNL Sub-System Moving to Stampede 2

Posted by Jesse Snead on May 10, 2017 11:20:57 AM

The Stampede 2 deployment continues to go well: we expect to begin Phase 1 production service during the week of June 7 with a full complement of 4,200 Intel Knights Landing (KNL) compute nodes. Later this summer we’ll begin Phase 2 deployment of an additional 1,736 nodes featuring an upcoming...

The Stampede 2 deployment continues to go well: we expect to begin Phase 1 production service during the week of June 7 with a full complement of 4,200 Intel Knights Landing (KNL) compute nodes. Later this summer we’ll begin Phase 2 deployment of an additional 1,736 nodes featuring an upcoming Intel processor. We will continue to downsize Stampede 1 as this transition proceeds, but Stampede 1 will remain available until Fall 2017 when Stampede 2 enters full production.

The next major step focuses on the 508 KNL nodes (https://portal.tacc.utexas.edu/user-guides/stampede#stampede-knl-cluster) that are currently in production as a sub-system of the existing Stampede cluster. On or about Wednesday, 17 May 2017 we will stop accepting new jobs on the KNL sub-system. We will do our best to allow pending jobs to run to completion before we permanently retire the login-knl1 login node. This will have no effect on the availability of your files: the Sandy Bridge and KNL sides of Stampede 1 share the same home, work, and scratch file systems.

Please watch TACC User News (https://portal.tacc.utexas.edu/user-news) for additional information over the next few weeks. For now, note that TACC will have no KNLs in production service for a 3-4 week period beginning in mid-May. The temporary absence of 508 KNL nodes will likely put additional pressure on the Sandy Bridge queues. We especially appreciate your patience with queue wait times as we continue the process of installing Stampede 2.

Please submit any questions you may have through the TACC Consulting System or feedback form.

The issues with the dvs server has been resolved and LS5 has been returned to production since 7pm CST. The queues were not emptied, however, and jobs running at the time of the failure were removed. Apologies for any inconvenience caused.

Lonestar5 Status 6 March 2017

Capacity on LS5 will be reduced and queue times are likely to increase in the short term. We will resolve this state...
