During February 2026, the developer contributed to the ISSMteam/ISSM repository by building installation scripts that enable streamlined integration of PETSc-powered capabilities, specifically targeting Adjoint PETSc and a defined PETSc version. Using bash scripting and software installation expertise, they established a stable workflow that allows ISSM users to easily install and leverage PETSc for scientific computing tasks. Their work focused on reducing setup complexity and laying the technical groundwork for future PETSc-based adjoint calculations and experiments. While no bugs were addressed during this period, the developer’s efforts provided foundational infrastructure to support downstream features and performance improvements within the ISSM project.
