PROFILE
Hseroussi
Contributed to the ISSMteam/ISSM repository by developing and refining data management and build configuration features for scientific computing workflows. Over four months, delivered enhancements such as configurable NetCDF data paths and host-based data routing, enabling flexible, environment-specific access to velocity and melt rate datasets. Addressed macOS build reliability by resolving library version conflicts and improving Fortran/MEXLIB integration, which reduced installation friction and improved cross-platform stability. Leveraged C++, MATLAB, and shell scripting to implement robust configuration management and data processing solutions. The work emphasized backward compatibility, reproducibility, and maintainability, supporting both end-user usability and streamlined onboarding for new contributors.

Oct 1, 2025October 2025 ISSM Development – Implemented host-based data routing for Rignot Ice Shelf Melt model data and introduced an alternate data path on the Totten host; fixed hostname mapping naming to ensure reliable data ingestion. The changes improved data availability, reduced data-load errors, and reinforced path-resolution consistency across environments.

Sep 1, 20252025-09 ISSM monthly summary focused on building reliable, cross-platform development and reducing installation/runtime friction for scientific users. Delivered critical build reliability improvements for macOS and Fortran/MEXLIB components, enabling stable, repeatable deployments and easier maintenance. Key outcomes: - Stabilized macOS builds by addressing compile-time array sizing and library version conflicts; updated PETSc to 3.23.6 with macOS libscalapack compatibility, reducing runtime stack issues and linker-related failures. - Fixed libtool-based Fortran/MEXLIB build issues by ensuring FORTRANLIB is included in MEXLIB, eliminating a known failure path on targeted machines. - Streamlined build configuration by removing problematic LDFLAGS, improving macOS compatibility across library versions (2.2.x vs 2.2) and reducing environment-specific build failures. Overall impact: - Enhanced reliability and reproducibility of builds for ISSM on macOS and Linux-like environments, lowering support burden and accelerating onboarding for contributors and users. - Strengthened cross-team collaboration through clear, reproducible fixes and references to commit-level changes. Technologies/skills demonstrated: - C/Fortran build tooling, libtool, PETSc integration, macOS build environment tuning, and cross-component compatibility with MEXLIB and libscalapack. - Diagnostics, issue isolation, and targeted fixes on multi-machine configurations.

Mar 1, 2025March 2025 – ISSM: Feature delivery and capability expansion. Delivered a configurable NetCDF data path for interpMouginotAnt2019, enabling reading velocity data from user-defined locations. The feature preserves existing default behavior when no path is provided, removing reliance on hardcoded hostname-based paths and improving deployment flexibility across environments. No major bugs were recorded this month; focus was on feature enhancement, code quality, and documentation. Business value includes increased usability for diverse workloads, easier on-boarding and reproducibility, and reduced maintenance burden. Technologies/skills demonstrated include API design for optional parameters, backward compatibility, Python/codebase integration, and robust version-control practices.
