TACC is offering this training on High Performance Computing (HPC) and parallel programming for Frontera and other TACC resources (Stampede2) on three separate days. During the first day (2/13) 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 (2/20) 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. The day ends with a session on parallel I/O. On the third day (2/27) we will cover advanced topics not discussed in previous sessions.

Most of the training segments have a hands-on component (lab) that will be conducted on Frontera (or Stampede2).  

This training is available to both in-person and remote attendees via webcast. Local participants are strongly encouraged to attend in-person.

Registration for each day closes 2 days before at 5pm CT. For more information and to register for each day of the event, please visit: https://learn.tacc.utexas.edu/

We are pleased to announce the Introduction to PETSc Training being held on February 6th, 2020 from 9am to 4pm CT.

The Portable Extensible Toolkit for Scientific Computing (PETSc) provides a framework for the development of computational science codes. Its focus is on solving linear and nonlinear systems, but it is more than a collection of algorithms: it is a complete toolkit supporting parallel data structures, linear algebra, PDEs, meshes. PETSc is designed for scalable parallelism and contains debugging and profiling support. This course will discuss the basic PETSc objects and how they make up a PETSc code. Upon completion of this course, you should be able to independently develop scalable scientific simulation codes with the PETSc library.

This training will be available to both in-person and remote attendees via webcast. Local participants are strongly encouraged to attend in-person. 

Registration for this event closes at 5pm CT on February 4th, 2020. To register for each session and for more information please visit: https://learn.tacc.utexas.edu/

We are pleased to announce the Containers @ TACC Training being held on December 6th, 2019 from 9am to 3pm CT.

Software containers are an important common currency for portable and reproducible computing.  Learn best practices on building, using, and sharing Docker and Singularity containers in this hands-on workshop.  Also learn how to run those containers on TACC HPC systems, including MPI and GPU aware containers.

This training is available to both in-person and remote attendees via webcast. Local participants are strongly encouraged to attend in-person.

Registration for this event closes at 5pm CT on December 4th, 2019. To register and for more information please visit:

We are pleased to announce the HPC Application Tutorial: VASP on Frontera and Stampede2 Training being held on December 5th, 2019 from 1pm to 4pm CT. This new training module helps beginner and intermediate users of the VASP software package to carry out calculations with desirable performance and efficient usage of resources on TACC systems. It covers basic procedures for running VASP on TACC systems like Frontera and Stampede2, including:

- how to use a TACC supercomputer,
- how to gain access to the TACC installed VASP software environment,
- how to build VASP in licensed user's accounts for debugging, and
- how to build VASP in licensed user’s accounts with 3rd-party extensions.

The training also introduces the general steps for determining the task topology for optimal performance and scaling of VASP jobs under the TACC computing environment. Furthermore, we present and explain some of the most common issues and solutions to help users save effort in troubleshooting VASP related errors.

This training focuses on the system and computing environment aspects and how to run VASP efficiently on TACC systems. It is not a tutorial for researchers on how to use VASP to solve science problems. Users need to refer VASP manual and forum for that purpose.

Registration for this event closes at 1pm CT on December 4th, 2019. To register and for more information please visit:
