The Texas Advanced Computing Center (TACC) will be deploying a new system, Frontera, in mid-2019, with support from the U.S. National Science Foundation as the first phase of the new NSF "Towards a Leadership Class Computing Facility" program.

This webinar will provide a brief overview of the plans for the new system and the broader project that surrounds it, review the architectural design choices made, and discuss the application community that will run on it. The presentation will also provide an update on the current landscape of systems at TACC, how they are used, and how usage is changing. 


This is the first of the upcoming series of Frontera training webinars. Please also join us for “MPI Foundations” on March 25 and “Programming for Advanced Architectures” on March 29. We’ll continue to send announcements for future Frontera training offerings.

The focus of this training will be on programming for advanced architectures on Stampede2. We'll also review the basics of vectorization, discuss the importance of multi-threaded programming, and cover the importance of hybrid programming on manycore architectures.

We will also provide practical information and advice to enable experienced OpenMP and MPI programmers to enhance applications on the manycore architectures. We'll provide recommendations regarding MPI and OpenMP task layout. Optimization methods in multithreading will be covered in depth. An overview of current profiling tools available on Stampede2 will also be presented.

Local participants are strongly encouraged to attend in-person. To register and for more information please visit: https://learn.tacc.utexas.edu/ If you have any questions please contact me at jasona@tacc.utexas.edu

This whole day workshop will instill in the participants fluency in the basic MPI constructs through a series of practical programming exercises. Participants will learn collectives, blocking and non-blocking two-sided communication, and a brief introduction to more advanced topics.

The emphasis of this workshop will be on doing hands-on exercises; there will be little lecturing. This course will be offered to in-person and webcast attendees. Local participants are strongly encouraged to attend in-person. Participants should have a basic command of Unix and a common Unix editor such as Vi or Emacs. Exercises can be done in C, Fortran, or Python.

A planned system maintenance for Stampede2 will be taken on February 26, 2019 from 8:00AM-7:30PM to install updates to the system software.  After the maintenance, the Intel 18 compiler will replace Intel 17 as the default compiler on Stampede2.  The Intel 17 compiler and software stack will remain available to those who load the appropriate modules explicitly.  See https://portal.tacc.utexas.edu/user-guides/stampede2/intel for more information.

Stampede2 will be unavailable from 8 a.m. to 7:30 p.m. (CT) on Tuesday, 8 January 2019. System maintenance will be performed during this time.

 

If you submit a job before the maintenance, and the time you request exceeds the time remaining until the maintenance begins, your job will run when the maintenance is over. The squeue command will report "ReqNodeNotAvailable" ("Required Node Not Available"). The showq utility will list the job as "BLOCKED" and report its status as "WaitNod" ("Waiting for Nodes"). Note that the hours leading up to the maintenance are an excellent time to submit shorter, smaller jobs that can complete before the maintenance begins: as the queues drain there will be many nodes available, and your wait time may be short.
