Stampede KNL Nodes Now Available

We are pleased to announce that Stampede's new Knights Landing (KNL) upgrade is now available for production use by all users with Stampede allocations. The KNL upgrade prepares the way for Stampede 2 by introducing second-generation MIC technology to Stampede. The upgrade adds to the existing Stampede system a total of 508 Intel Xeon Phi 7250 KNL compute nodes that boost Stampede's performance by an additional 1.2 petaflops. The KNL represents a radical break with the first generation Knights Corner (KNC) MIC coprocessor. Unlike the older KNC coprocessor, each Stampede KNL is a stand-alone processor that is the sole processor in its node. Intel refers to the KNLs as self-hosted or self-boot processors.

The new KNL nodes and the older Sandy Bridge nodes in the main Stampede cluster share the same three Lustre file systems. In most other ways, however, the KNL nodes form a largely independent cluster distinct from the original Sandy Bridge cluster. The KNL cluster has a dedicated Haswell login node (login-knl1.stampede.tacc.utexas.edu), a separate OmniPath network, a KNL-compatible software stack, its own SLURM scheduler, and KNL-specific queues.

The updated Stampede User Guide https://portal.tacc.utexas.edu/user-guides/stampede now reflects the KNL upgrade. A self-contained KNL section near the end of the updated user guide amounts to a Quick Start for those already familiar with Stampede. We also recommend consulting the training materials, tutorials, and hands-on exercises linked to in the References section. Finally, be sure to consult Intel references, especially the rich collection accessible through the Intel Developer Zone.

A few administrative notes:
  • Note that the KNL upgrade adds new nodes (and new capabilities) to the system, but leaves the original Stampede hardware intact. The Sandy Bridge nodes and their legacy KNC coprocessors remain available to all users.
  • Note that all Stampede users have access to KNL - there are no special permissions or allocations required.
  • Access to login-knl1 requires Multi-Factor Authentication (MFA). Users can create an MFA pairing on the TACC User Portal. After logging in, go to your account profile (Home->Account Profile), then click the "Manage" button under "Multi-Factor Authentication" on the right side of the page. Please see Multi-Factor Authentication at TACC for more information and instructions.
  • Despite the fact that KNL has 68 cores per node, your allocation will be charged the lower rate of 16 SUs per KNL node-hour (the same charge as a Sandy-Bridge node-hour). It may take a few days for charges from this week's KNL jobs to show up in your allocation balance.
Thank you for your interest in TACC, and best wishes in your work on KNL.

The Lonestar 5 large memory queues are now available. Eight 512GB Haswell nodes are available to all users through the largemem512GB queue. Two 1TB Ivy Bridge nodes are available to approved users through the largemem1TB queue. These large memory compute nodes are accessible from the standard LS5 login nodes, but in many ways they form a largely independent cluster with its own Infiniband connectivity, Slurm scheduler, queues, and software stack. The TACC-largemem module provides access to the large memory nodes. 


Please see the Using the Large Memory Nodes section of the Lonestar 5 User Guide for instructions on using these special queues.  Note that the new documentation associated with the large memory queues is significantly different than the original descriptions that appeared in earlier releases of the User Guide.

We are adding an additional hardware repair to tomorrow's maintenance: Wrangler's Hadoop queue will be 50% unavailable from 11am tomorrow. Estimated duration will be 1 hour. The unaffected nodes will remain available for hadoop jobs.

Kelly Gaither, Brian McAnn, and Matthew Vaughn from the Texas Advanced Computing Center will co-teach an innovative new course at Cold Spring Harbor Laboratory December 1 - 10, 2016 aimed at jump-starting use of immersive, interactive visualization in biology. The course is aimed at researchers who wish to design and implement innovative visualization tools to help address biological or biomedical research questions. As part of their research programs, course participants will ideally have a need to visualize genomic or systems biology data, anatomical structures and models, scientific simulations, and/or other domains that generate complex, multidimensional, and often very large data sets.

The application deadline for this course is August 15, 2016.

Multi-Factor Authentication now available

Posted by Jesse Snead on Jul 13, 2016 3:43:47 PM

Effective on September 27, 2016, all users must authenticate using Multi-Factor Authentication (MFA) in order to access TACC resources. MFA adds an extra step to the login process, requiring an additional ‘factor’ other than a password to log into a machine. A factor may be: 

  • Something the user knows: a password 
  • Something the user possesses: a mobile phone, or hard token 
  • Something the user is: fingerprint or other biometric scan 
MFA typically requires users to provide two or more of these factors to authenticate. Adding another factor to the login process creates a layered security, making it far more difficult for an unauthorized user to access a resource. This provides a higher level of security for themselves and the user community as a whole. 

TACC users may NOW set up MFA on their accounts in one of three ways:  
  1. The TACC Token app 
  2. SMS (text) messaging 
  3. Possession of a TACC Hard Token 
Please visit the following URL for more information on MFA and instructions on enabling MFA for your TACC account. 

https://portal.tacc.utexas.edu/tutorials/multifactor-authentication  

Access to TACC resources through MFA will become mandatory effective Tuesday, 27 September 2016, but users are strongly encouraged to start using this method of access as soon as possible. 

Also: Note that setting up MFA for your TACC account is different than the DUO MFA solution recently announced by The University of Texas at Austin and the NSF XSEDE project. Neither DUO option will work when trying to directly connect to TACC resources. XSEDE users connecting to TACC resources via the XSEDE Single Sign Hub will NOT be required (for now) to set up MFA on their TACC accounts.

Wrangler maintenance is now complete. This was a major upgrade; many software packages have changed. 

1. Please let us know of any broken modules or problems with your workflow by submitting a ticket. 
2. Three software packages were not successfully upgraded: VLC, FFmpeg and MariaDB. If you require the first two, please submit a ticket. MariaDB will be available as soon as it is completed and tested. 
3. The login nodes and the nodes in 251-[101-143] now differ in what libraries they support. If you are rebuilding code and know that your jobs will run on the upgraded nodes, then please establish an interactive session (idev -p normal) and build in that.
4. Should your jobs be urgent, the fallback remains to run on the 252-[101-143] nodes which remain unchanged (but note that there is no GPFS file system). Testing is well underway to upgrade these nodes in the near future so it is worth at least trying your jobs on the upgraded software stack.

Wrangler's maintenance period has been extended into today, Wednesday June 29th. 

The 'hadoop' queue is still available for running jobs and the /data and /work directories are still available from those nodes.
