This is an archive of class materials presented in August 2019. Here is the course description related to that presentation.

Are you in need of highly parallel computing at an unprecedented scale? TACC is currently deploying NSF's new flagship system Frontera, which will serve the ever growing needs of the scientific community. We invite you to join us at TACC for a full day of presentations and discussions focused on Frontera’s outstanding capabilities. We will introduce the system and its new and innovative components, and will discuss how to optimally compile, launch, and execute scientific applications at large scale. Much emphasis will be put on the description of available MPI stacks and on tuning MPI and hybrid (MPI+OpenMP) applications via environment variables. The schedule will allow for many opportunities to interact with TACC staff and to discuss general and/or user specific topics. This event is open to the large early-user community that is already using Frontera, and to any current or future user of TACC resources.
