Dreyer, Lukas

Developed and integrated forest profiling instrumentation into the DLR-AMR/t8code repository to measure the runtime performance of core forest operations, including tree offsets, forest offsets, and first descendant calculations. Using C++ and leveraging parallel computing techniques, the work focused on capturing detailed timing data for large array scenarios, enabling the identification of performance bottlenecks. Performance profiling hooks and baseline metrics were established to support future optimization and validate improvements. This targeted feature provides actionable insights for data-driven enhancements, ensuring that the codebase can efficiently handle demanding workloads and guiding ongoing efforts to optimize computational performance in forest data structures.
