Meetings & Workshops
Crusher User-Experience Talks
December 9, 2022, 2:00 – 3:30 PM (EST)
Virtual via Zoom
Contact: Tom Papatheodore (firstname.lastname@example.org).
Crusher is the OLCF’s 192-node test-and-development system with identical node architecture as Frontier. It serves as the main development platform for the Frontier Center for Accelerated Application Readiness (CAAR) and Exascale Computing Project (ECP) teams as they prepare their applications and software for Frontier. In this session, we will hear from 3 of these teams, who will share their experiences porting their applications from Summit to Crusher, optimizing for the platform, and giving some helpful tips to future users of the Frontier system. Please register below to hear from the following application teams:
- Cholla – GPU-based hydrodynamics code
- NuCCOR – Nuclear physics application for deciphering the structure and reactions of atomic nuclei
- Lattice QCD – Nuclear physics application used to calculate interactions of sub-nuclear elementary particles – quarks & gluons.
All participants must register to attend this event.
Using HIP and GPU Libraries with OpenMP
December 14, 2022, 1:00 – 2:30 PM (ET), Virtual via Zoom
This training is designed for Fortran and C/C++ users who are using OpenMP or considering OpenMP for their applications on Frontier. The focus will be showing how one can augment an OpenMP program with GPU kernels and libraries written in HIP. We build on the previous OpenMP training in OLCF’s “Preparing for Frontier” series OpenMP Offload Basics and OpenMp Optimization and Data Movement. For Fortran OpenMP programmers, we will demonstrate how to build or use the C-interoperability interfaces to launch HIP kernels and call ROCm libraries (for example, rocBLAS, rocFFT, etc.), while using OpenMP to manage data allocation and movement. Users of OLCF, ALCF and NERSC are welcome to attend this training.

Frontier Training Workshop
February 15-17, 2023
Virtual via Zoom
The Oak Ridge Leadership Computing Facility (OLCF) will host a virtual Frontier Training Workshop February 15-17, 2023. This event is meant to help new Frontier users (or those intending to use Frontier) learn how to run on the system. The first day will feature presentations and a hands-on session. The last two days will feature presentations from vendors and staff. The presentations for this workshop are meant to deliver relevant information about the system (hardware, job launcher, programming methods, etc.), while the hands-on session is intended to help participants learn how to run jobs on the system. To participate in the hands-on, you must have an account on Frontier or Crusher. For more details and to register see: https://www.olcf.ornl.gov/calendar/frontier-training-workshop-february-2023/
December 2022 OLCF User Conference call
December 14, 2022, noon – 1:00 PM (EST)
The December OLCF User Conference Call will be held from noon until 1:00 PM Eastern Time on Wednesday, December 14. During this call, HPCToolkit’s John Mellor-Crummey will give an overview of HPCToolkit and how to utilize it on OLCF systems. For more information, see the event page at https://www.olcf.ornl.gov/calendar/userconcall-dec2022/
– Summit, Andes, DTN, Alpine Filesystem, Marble, Crusher, Spock, Citadel, and jupyter.olcf.ornl.gov will be unavailable from 8:00 AM, December 13 to 8:00 AM, December 14
