This October, TACC is offering training on High Performance Computing (HPC) and parallel programming for Frontera on three separate days. During the first day (10/15) we focus on parallel programming with OpenMP. We provide an introduction to OpenMP in the morning and delve into advanced topics in the afternoon. On the second day (10/22) the focus shifts to MPI, again covering an introduction and some advanced topics. We also discuss hybrid computing and the interplay between OpenMP and MPI within a single code. On the last day (10/29) we will discuss Parallel I/O, HPC tools, debugging, profiling, and best practices on TACC machines time permitting.  

Each day will have a hands-on component (lab) that will be conducted on Frontera.  

This training sessions will be available to remote attendees via webcast. Dates are tentative and registration for each of the sessions will be opened on learn.tacc.utexas.edu during the second week in September.  An additional announcement will be posted at that time.

Please email jasona@tacc.utexas.edu if you have any questions.

Frontera will be reserved for Texascale Days - very large scale runs of at least 4,000 nodes up to full system - to be held immediately following the system maintenance September 1 through Monday September 7. This event allows our researchers the opportunity to work on problems that may not be possible at the smaller scale. To be eligible to participate, your application must have already successfully run on at least 2,048 nodes in the Large Queue on Frontera.If you would like to participate in Texascale Days, please submit a ticket and include a brief description of the experiment you would like to run and how many nodes would be required.  If you have not yet run at 2,048 nodes and would like to request access to the large queue, include this in your request. This should include your own strong or weak scaling results from Frontera on up to 512 nodes.If you have already run in the large queue on at least 2048 nodes, you are qualified to request a Texascale reservation to try running at 4,000 nodes or more.

Frontera's /scratch1 filesystem currently has two of its Lustre storage targets offline due to errors on them and we are working with the vendor to restore it, but it might take some time. For now, the compute queues have been closed and the target has been deactivated on the login nodes to prevent hangs when trying to use the filesystem, but users will get errors if they attempt to access files residing on the offline target. If the repair will take more than a few hours, we will deactivate the target on the compute nodes and re-open the queues, however, jobs will fail if they try to access a file on that target. New files can be created on the other storage targets for /scratch1 without any errors.
