Meeting & Workshops

Introduction to High-Performance Parallel Distributed Computing Using Chapel, UPC++ and Coarray Fortran
Hosted by ECP, NERSC, and OLCF
Virtual (You must register to get the zoom joining link)
July 26-27, 12:00 PM – 3:25 PM EDT

In this tutorial, we show how example computations such as heat diffusion, k-mer counting, file processing, and distributed maps can be written to efficiently leverage distributed computing resources in the Chapel, UPC++, and Fortran parallel programming models. This tutorial should be accessible to users with little-to-no parallel programming experience, and everyone is welcome. Attendees will be shown how to compile and run these programming examples, and provided opportunities to experiment with different parameters and code alternatives while being able to ask questions and share their own observations.

Frontier Training Workshop
Virtual via Zoom
August 23-25, 2023, 1:00 PM – 5:00 PM EDT

The Oak Ridge Leadership Computing Facility (OLCF) will host a virtual Frontier Training Workshop August 23-25, 2023. This event is meant to help new Frontier users (or those intending to use Frontier) learn how to run on the system. The workshop will feature presentations and demonstrations from vendors and OLCF staff. The target audience for this workshop is OLCF users who have recently obtained access to Frontier or who intend to run on Frontier in the future. ALCC users are encouraged to attend.

HIP Training Series
Main series page:
First session:
Second session:

HIP is a parallel computing platform and and programming model from AMD that extends C++ to program GPUs, with an API very similar to CUDA but supporting Nvidia and AMD GPU targets. The HIP training series will introduce GPU programming concepts from basic GPU programming, porting your existing GPU applications to HIP, profiling and tracing your HIP code, among others. Each session will be 2 hours with a lecture and hands on portion. The hands on portion is open to existing users of OLCF’s Frontier. Registration is open for the first session at and the second session at Visit the main series page at

Upcoming Downtimes

  • The SPI Data Transfer Nodes will be unavailable from 7:00 AM until noon on Tuesday, August 1
  • Andes and the Data Transfer Nodes will be unavailable beginning at 8:00 AM on Tuesday, August 8. The DTNs will return to service at 5:00 PM; Andes will remain unavailable until 11:59 PM.

Frontier and Crusher TDS Upgraded to New System Software
During the July 18 outage, the Frontier and Crusher TDS systems were upgraded to a new version of the system software stack. This upgrade makes ROCm 5.5.1 and HPE/Cray Programming Environment 23.05 available. To exercise the new versions of these packages, users must load the `rocm/5.5.1` and `cpe/23.05` modulefiles. Please note that the Known Issues sections for Frontier and Crusher have been updated with issues identified during testing. For more information about the upgrade, please see the Frontier System Updates and Crusher System Updates sections.

If you encounter any issues or have questions, please contact

July 2023 OLCF User Conference Call – Data Transfer Overview is Today (Jul 26)
The July OLCF User Conference Call will be held from noon until 1:00 PM Eastern Time today (Wednesday, July 26). During this call, OLCF’s Suzanne Parete-Koon will give an overview of how to transfer data within OLCF. This will include transferring data between Alpine and Orion, how to use Globus, and more. This will be helpful for users looking to transition their data from Summit to Frontier. For more information, see the event page at

2023 OLCF User Meeting (Oct 17-18)
The OLCF invites you to participate in the 2023 OLCF User Meeting at Oak Ridge National Lab in Oak Ridge, TN. The purpose of the annual user meeting is to share selected computational science and engineering achievements emerging from OLCF’s user programs, to enable direct interactions among users, advance OLCF’s relationships with our user community, and provide Facility updates. The meeting will be available to virtual participants via Zoom, but elements of the meeting like the poster session and Facility tours will only be available to the onsite attendees. All attendees (whether onsite or virtual) will need to register. For more information or to register, please visit

10th WACCPD Workshop @ SC23 Call For Papers
The Call for Papers for the 10th Workshop on Accelerator Programming and Directives is now open! The workshop aims to showcase all aspects of accelerator programming for heterogeneous systems such as innovative high-level language or library approaches, lessons learned while using directives or other portable approaches to migrate scientific legacy code to modern systems, and compilation and runtime scheduling techniques. The paper submission deadline is August 4, 2023 AOE. For more information, see

1st HPCTESTS 2023 Workshop @ SC23 Call for Papers
The First International Workshop on HPC Testing and Evaluation of Systems, Tools, and Software (HPCTESTS 2023) Call for Papers is now open! HPCTESTS 2023 brings together HPC researchers, practitioners, and vendors from around the globe to present and discuss state-of-the-art HPC system testing methodologies, development of tools, benchmarks, tests, procedures, and best practices to evaluate the status of a system and its software throughout its life. The papers submission deadline is August 10, 2023 AOE. For more information, see
