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...

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.  

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

Updated on Jun 29, 2016 5:13:34 PM

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.

Updated on Jun 29, 2016 8:52:34 AM

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.

Parallel Computing With OpenMP Training

Updated on Mar 29, 2016 1:48:37 PM

The course description has been revised to include an agenda and additional details for this event. Please review the following updated description.

The course will cover features that are becoming more important to HPC as shared-memory microarchitectures are becoming more complex, and the need for directing the parallel execution of even more complex coding paradigms is becoming paramount to achievement of efficient programming and optimal performance.

Three major topics will be explored to address these challenges.

1.)OpenMP Tasking basics:
Syntax and operation, synchronization, data-sharing model, dependencies and prioritization. Examples and lab will show how to generate tasks and control tasking for while loops, task loops, pointer chasing and tree searchers as well as show how to set up task dependences among tasks.

2.) OpenMP SIMD basics:
SIMD syntax and combination with parallel loop directives. SIMD directives are used to advise compilers about execution of loops within the SIMD execution units (vectorization). For instance, this includes use of linear variables, alignment of arrays and forced SIMD execution. Moreover, the declare SIMD directive provides mechanism for creating vectorized functions. Examples and lab will illustrate vectorization of loops and functions for optimally executing code in SIMD logical units.

3.) OpenMP Thread Affinity basics:
Declaration of places and bind operations. OpenMP now provides a general, non-vendor-specific syntax and runtime control to place threads of a work-sharing loop (and nested loops). The control can be directed to abstract places (cores, sockets, etc.) or numbered places (cpu ids). Also, binding policies describe mapping distributions. Examples and exercises will illustrate situations where affinity may be needed for testing and/or obtaining optimal thread binding.

After presentation topics labs will provide experience for using syntax and concepts, in simple-to-understand examples; and experiments on codes will test understanding. Late afternoons will be used for lab reviews and providing assistance with users who are interested in implementing new OpenMP features in their code. (The latter is limited to availability of the three instructors.) Additional OpenMP features (including proposed 5.0 features) may be discussed in the late afternoon if time permits.

Python is a commonly used language for scientific application development. To take full advantage of modern supercomputing resources or even modest HPC clusters with Python based applications it is crucial that the developer understand how to parallelize their code.

This class will cover the Python module, mpi4py, that provides a Message Passing Interface (MPI) implementation and enables multi-node computation. In addition, the multiprocessing module, which provides general multi-process computation, will be covered. Both topics will be illustrated through hands-on examples.

This course is intended for students that have proficiency with the Python language and with the Linux OS command-line. In order to participate in the lab exercises, students' machines must have ssh/terminal capability and have logged into TACC HPC systems.
