Create an Account

Fill out the account request form on the TACC Account Management Portal and it will be reviewed by our User Services team.

Faculty, professional research staff, and postdoctoral researchers may request Principle Investigator (PI) eligibility for their account. PIs are responsible for requesting system allocations and managing their team.

Graduate and undergraduate students can create an account, but must be added to allocations by PIs to use the systems.

Training & Events

Best Modern CMake Practices and Performance Portability with CMake and Kokkos

The course will begin with a brief introduction to CMake, along with a refresher on writing maintainable CMake build systems to ensure that everyone attending is up to date. The course will then progress to Modern CMake best practices, including covering generator expressions, installing targets, and tips to improve your CMake scripts. Finally, the course will cover portable GPU programming with CMake and Kokkos, and then there will be time at the end of the course for an open question and answer session.

Advanced Nvidia HPC SDK Training

NVIDIA will present a two day training session software for High Performance computing developers to build and optimize applications that run on NVIDIA GPU-accelerated systems. We'll cover NVIDIA's HPC SDK, including compilers (C, C++, Fortran), libraries (math, communication), and tools, as well as cover best practices to enable scientists to effectively use NVIDIA software for high performance computing. In addition to the HPC SDK, we'll do a deeper dive on C++ Standard Parallelism, profilers and correctness tools like NSight Systems, NSight Compute, and Compute Sanitizer, as well as a tutorial on NVIDIA's newest GPU Programming model, CuTile.
