Call for Abstracts for Quantum Computing User Forum

The Quantum Computing User Forum will be held August 12-15, 2024 in Oak Ridge, TN. The forum serves to foster engagement between users, vendors, and subject matter experts from national laboratories, industry, and academia. The agenda will consist of invited and contributed talks from the diversity of users represented by the Quantum Computing User Program (QCUP). A summary of last year’s event is available online. The call for abstracts for contributed talks and posters is now open.

All QCUP users are eligible to submit before the deadline of March 15, 2024. Submissions must indicate the QCUP project ID and abstract summary to be considered. Additional online information may be submitted by providing the DOI number, e.g., from publication or pre-print server. Additional inquiries may be submitted to the Quantum Computing User Program administration team by emailing

Meetings & Workshops

Performance Portability for Next-Generation Heterogeneous Systems
Monday, February 26th, 2024
1:00 PM – 2:30 PM (EST)
Virtual via Zoom

Our high-performance applications must be written to embrace the full ecosystem of supercomputer design. They need to take advantage of the hierarchy of concurrency on offer, and utilize the whole processor. And writing these applications must be productive because HPC software outlives any one system. Our applications need to address the “Three Ps” and be Performance Portable and Productive. This talk will highlight the opportunities this variety of heterogeneous architectures brings to applications, and how application performance and portability can be rigorously measured and compared across diverse architectures. It will share a strategy for writing performance portable applications and present the roles that ISO languages C++ and Fortran, as well as parallel programming models and abstractions such as OpenMP, SYCL and Kokkos play in the ever-changing heterogeneous landscape.
Presenter: Tom Deakin, University of Bristol (

OLCF New User Training
Virtual via Zoom
February 28, 2024. 1:00  PM – 4:30 PM (ET)

The Oak Ridge Leadership Computing Facility (OLCF) will host a virtual New User Training Workshop on February 28, 2024. This event is meant to help new Frontier and Summit+ users learn how to run on the OLCF system. The workshop will feature presentations and demonstrations from OLCF staff.
For agenda and registration see:

February 2024 OLCF User Conference Call
Gordon Bell User Experience Talk
February 28th, noon – 1:00 p.m EST

The February OLCF User Conference Call will be held from noon until 1:00 PM Eastern Time on Wednesday, February 28th. During this call, the winners of the 2023 ACM Gordon Bell Award will give an overview of their experiences running at scale on Frontier. For more information, see the event page at

NERSC: AMReX Tutorial
March 1st, 12:00 p.m. EDT

The AMReX training session, presented by Andrew Myers, Weiqun Zhang, and Mukul Dave of LBNL, is part of the Performance Portability training series. This series, offered by OLCF, NERSC, and ALCF, features training sessions on various performance portable programming solutions to help ease developer transitions between current and emerging high-performance computing (HPC) systems, such as the NERSC Perlmutter, OLCF Frontier, and ALCF Aurora featuring NVIDIA-, AMD-, and Intel-based GPUs, respectively.

AMD & HPE Profiler Tutorial

Friday, March 1st, 2024
1:00 PM – 3:15 PM (EST)
Virtual via Zoom
Contact: Suzanne Parete-Koon (

Collecting and presenting data on the performance of kernels or full applications can help identify key optimizations in code for better performance on Frontier. To help get you started learning what tools are available for code optimization, AMD will give an Overview Omniperf, a comprehensive collection and visualization of performance counters with support for GPU Speed-of-Light Analysis, Empirical Roofline Analysis, Memory Chart Analysis and Kernel Comparisons. And HPE will give an overview of HPE’s Performance Analysis Tools, designed to provide an integrated infrastructure for measurement, analysis, and visualization of computation, communication, I/O, and memory utilization. All are welcome, but March Frontier Hackathon teams are most strongly encouraged to attend.
