ALCF Hands-on HPC Workshop
Held in October at Argonne, the 2025 ALCF Hands-on HPC Workshop welcomed 90 participants, including both current and new ALCF users. The workshop was organized as a two-part program, both virtual and in-person, designed to help users build and advance their skills in HPC and AI. The virtual week introduced the fundamentals of building, compiling, and running applications on ALCF systems and was strongly recommended for new users. The in-person week provided in-depth sessions and hands-on time with ALCF staff and industry experts. Participants worked on Aurora, Polaris, and AI Testbed systems, focusing on porting applications to heterogeneous architectures (CPU + GPU), optimizing code performance, and developing AI/ML workflows.

ALCF INCITE GPU Hackathon
In May, the ALCF hosted its annual INCITE GPU Hackathon, a hybrid event designed to help developers accelerate their codes on ALCF systems and prepare for the INCITE call for proposals. The multi-part hackathon included a three-day virtual week, a special session on DAOS, and a three-day in-person event that brought together more than 100 participants. Attendees had access to ALCF systems and were supported by experts from DAOS, Intel, TAU, and HPCToolkit. Many teams successfully integrated new tools during the event, and more than 90% indicated plans to apply for the INCITE program. For a recap of the event, read the article about the 2025 hackathon.
ATPESC
The annual Argonne Training Program on Extreme-Scale Computing (ATPESC) is an intensive two-week program focused on essential skills and tools for using supercomputers in scientific research. Organized by ALCF staff, the program features talks from leading computer scientists and HPC experts, along with hands-on training using DOE leadership-class systems at ALCF, Oak Ridge Leadership Computing Facility, and NERSC. In 2025, ATPESC welcomed 75 attendees from 48 institutions worldwide.
INCITE Proposal Writing Webinars
In the spring, the INCITE program, ALCF, and the Oak Ridge Leadership Computing Facility jointly hosted two webinars on tips and strategies for writing a strong INCITE proposal.
Monthly ALCF Webinars
The ALCF continued to host the monthly ALCF Developer Sessions, aimed at training researchers and increasing the dialogue between HPC users and the developers of leadership-class systems and software. Speakers in the series included developers from Argonne and HPE, covering topics such as accelerating AI training and inference on Aurora, best practices for coupling simulation and AI on ALCF systems, and using the ALCF Inference Service.
Getting Started on Aurora Bootcamps
In February 2025, Argonne hosted the Getting Started on Aurora Bootcamps, a virtual event introducing users to Aurora. Attendees explored early production workflows, best practices for compiling and running applications, hardware overviews, debugging and profiling tools, AI frameworks, and DAOS, with live demonstrations and Q&A supported by Argonne staff.

ALCF Service-Enabled Science Training Series
Launched in 2025, the ALCF’s Service-Enabled Science training series helps researchers leverage the full suite of ALCF computing resources, services, and tools to accelerate scientific discovery. Participants learn to streamline workflows; enable secure collaboration; and access advanced capabilities including Globus, the ALCF Inference Service, data sharing platforms, and workflow tools. The series includes webinars and hands-on sessions with real-world datasets, featuring success stories from teams using these services to advance their research. The first session was held in October and highlighted how on-demand computing and Globus tools support experiment-time analysis on Polaris.
