Developed a comprehensive HPCToolkit hands-on tutorial and example suite for the argonne-lcf/ALCF_Hands_on_HPC_Workshop repository, focusing on practical onboarding for high-performance computing performance analysis. The work included creating setup scripts, Makefiles, and detailed READMEs to guide users through building, running, and analyzing performance data with tools like OpenMP and SYCL. By incorporating GPU offloading techniques and example programs, the contribution enabled participants to explore diverse performance scenarios and reproducible workflows. Leveraging skills in code profiling, shell scripting, and C++, the project enhanced workshop readiness and provided a structured, end-to-end workflow for hands-on learning in HPC environments.
