PROFILE
Anish Sarkar
Over four months, contributed to the quokka-astro/quokka repository by developing features and resolving bugs in computational physics and simulation modeling. Delivered a turbulence driving module that enables high-fidelity turbulent flow simulations, integrating new parameters and structures in C++ to manage turbulence effects and adding tests to ensure correctness. Enhanced build reliability and onboarding for AMD GPU users by improving documentation and build system instructions, including CMake configuration and environment setup. Addressed a critical bug in turbulent driving logic to improve output accuracy and optimized velocity dispersion computation, reducing unnecessary calculations. Demonstrated strengths in C++ development, GPU programming, and algorithm optimization.
