Could you build this?
No Writing high-throughput parallel physics simulation software on CPU requires specialized expertise in low-level multithreading, memory layout optimization, and deep integration with MuJoCo's C API.
What it would actually take: This requires wrapping the C API of MuJoCo using Cython or C++ (pybind11), managing shared-memory buffers without Python GIL contention, and implementing lock-free task distribution across CPU cores with AVX/vectorized math considerations. Deep understanding of rigid body dynamics engines, memory alignment, and cache locality is mandatory.
