PROFILE
Ernesto Casablanca
Ernesto contributed to the ERGO-Code/HiGHS repository by enhancing build system reliability and enabling GPU-accelerated workflows. He implemented automatic detection of compiler intrinsics and MSVC-specific optimizations in C++ to improve runtime performance and stabilized Windows builds by refining Bazel configurations and dependency management. Ernesto also introduced CUDA build support, allowing configurable GPU acceleration for CUPDLP, and updated documentation to guide adoption. His work addressed cross-platform testing issues by improving resource discovery for Windows tests, resulting in more robust CI coverage. Through focused use of Bazel, C++, and CUDA, Ernesto delivered targeted improvements that deepened the project’s build and testing infrastructure.
