ALCF Hands-on HPC Workshop

2025 ALCF Hands-On HPC Workshop

The ALCF is hosting a Hands-on HPC Workshop which features both:

• Virtual event on September 23--25 and an
• In-person event on October 7--9, 2025, at the TCS Conference Center at Argonne National Laboratory.

The workshop will provide an opportunity for hands-on time on Aurora, Polaris and a few of the AI Testbeds focusing on porting applications to heterogeneous architectures (CPU + GPU), improving code performance, and exploring AI/ML applications development on ALCF systems.

Overview

The repo is divided into sections following the schedule of both the virtual and in-person weeks:

Virtual Week, Day 1

• Hardware Overview of Aurora
• Building, Compiling and Running Applications on Aurora
• CPU and GPU affinity on Aurora
• Programming Models

Virtual Week, Day 2

• Intel's Data Parallel Extensions for Python (DPEP)
• Learning Frameworks & Distributed Deep Learning on Aurora
• Foundation Models on Aurora
• Workflows
• Inference Service
• Agentic Workflows

Virtual Week, Day 3

• Tools

Obtaining the material and running the examples

Please clone the repo while on a Polaris or Aurora login node:

git clone --recurse-submodules https://github.com/argonne-lcf/ALCF_Hands_on_HPC_Workshop.git

Then navigate to the particular material of interest and follow the instructions for executing the hands-on examples.
