We are pleased to announce the BOINC@TACC Training being held on May 10th, 2019 from 1pm to 3pm CT.
The BOINC@TACC project is based on the Volunteer Computing (VC) model. It helps the TACC/XSEDE researchers in running applications from a wide range of scientific domains on the laptops, desktops, tablets, or cloud-based Virtual Machines (VMs) owned by volunteers. With BOINC@TACC, students and researchers can run small high-throughput computing jobs (that is, the jobs that involve small amounts of data transfer and processing), without spending their active project allocations.
This training will be available to both in-person and remote attendees via webcast. Local participants are strongly encouraged to attend in-person.
Please contact me at jasona@tacc.utexas.edu if you have any questions.
The workshop will alternate lectures with lab exercises, which can be done in C/C++/Fortran90/Fortran2008 and Python. Prerequisites: a mastery of basic MPI and use of Unix, including text editors.

In this class, our TACC Vis Staff will provide and overview on software data visualization as well as training on the use of the Paraview software package to visualize data sets on Stampede2 and Lonestar5.
Lonestar5 will not be available from 8 a.m. to 5:30 p.m. (CT) on Tuesday, 2 April 2019. System maintenance will be performed during this time.
GPU and VIS queues have been reopened after a correction to the Nvidia drivers.
Lonestar5 has been returned to production and the queues reopened.
At this time, maintenance has been finished.
Access to all TACC systems will be unavailable from 8:00 AM CDT until 4:00 PM CDT on March 31, 2019 to allow for upgrades to the TACC core network hardware. Jobs will continue to run, but users will have no access to TACC services and systems until the upgrade is complete.
This is the first session in a two part training series that will cover an introduction to the Machine Learning and Big Data processing platforms, programming models as well as libraries and tools that are specifically designed for data-driven analysis.
Each session will be three and a half hours long with approximately three hours of lecture and a half hour of hands-on practice. More details on the specific content covered during each session will be available closer to the session start date.

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.
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.
Lonestar5 will not be available from 8 a.m. to 5:30 p.m. (CT) on Tuesday, 12 February 2019. System maintenance will be performed during this time.
LS5 maintenance on Tuesday 2/12/19 is no longer necessary and has been cancelled.
Lonestar5 is experiencing a maintenance issue and the Lonestar5 administrators are working to correct the problem.
Access to LS5 has been restored. Running jobs affected by the outage will need to be resubmitted. We are sorry for any inconvenience this may have caused.
Due to Lonestar5 issues, we are initiating an emergency maintenance period. Lonestar5 will be down during this period and we will continue to update user news.
The following TACC systems will be unavailable from 8:30 a.m. to 5 p.m. (CST): Jetstream, Maverick, Maverick2, Catapult, Chameleon, Lonestar5, Wrangler, Fabric. Scheduled maintenance will be performed during this time.
Maverick and Maverick2 are back in production.
Queues on Lonestar5 have been opened again.
A maintenance window has been scheduled this Thursday, January 10th from 5pm-6pm CST for license update. Individual server instances will be intermittently unavailable during the maintenance.
TACC personnel will observe the University of Texas at Austin winter break from 5 p.m. (CST) on Friday, 21 December 2018, and will resume normal business hours on Wednesday, 2 January 2019. A staff member will be on site to monitor the status of all TACC resources. TACC support staff will monitor the consulting system throughout the break and address critical system issues. The staff will address other issues beginning Wednesday, 2 January 2019.
Please submit any questions you may have via the TACC Consulting System.
Due to an issue with DVS servers we've had to temporarily suspend the itar queue. We'll resume this queue as soon as we have a resolution.
Access to all TACC systems will be unavailable from 8:30 AM CDT until 1:30 PM CDT on December 9, 2018 to allow for upgrades to the TACC core network hardware. Jobs will continue to run, but users will have no access to TACC services and systems until the upgrade is complete.
Maintenance on listed systems has been completed.
Lonestar5 will not be available from 8 a.m. to 5:30 p.m. (CT) on Tuesday, 11 December 2018. System maintenance will be performed during this time.
The Lonestar5 maintenance scheduled for 11 December, 2018 is being postponed and will be announced, with the usual 2 week notice period, for a date in 2018.
Lonestar5 currently has issues with the scratch filesystem and some jobs are likely to fail. We're currently working to restore full access from all clients.
The scratch filesystem on ls5 was returned to service earlier in the day.

Lonestar5 is back in production. We apologize for the extended outage.
The maintenance on Lonestar5 is being extended for further testing prior to release.
Lonestar5 is having issues with queuing jobs at present. Administrators are working on it and we hope to resolve this as soon as possible.
All Lonestar5 queues are now running properly. Thank you for your patience.
Due to errors on the backend storage of LS5. We are going to reboot LS5. We will bring it back into service as soon as possible.
The Corral-TACC Filesystem has been restored on Lonestar 5.
