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.
