During October 2024, Giannos focused on improving the reliability of MPI job submissions for the Zorbas cluster within the MITgcm-contrib/ecco_darwin repository. He addressed a persistent issue in the run_on_zorbas.sh script by removing spurious carriage returns and eliminating a redundant partition setting, which previously led to misconfigurations and resource contention. Using Bash and shell scripting, Giannos applied dos2unix to standardize line endings, ensuring consistent execution across environments. His work enhanced the automation and stability of high-performance computing workflows, reducing manual intervention and submission failures. The depth of the fix demonstrated practical expertise in HPC environments and cluster job management.
