Could you build this?
No Creating a CUDA SDK that swaps memory between host RAM and GPU VRAM with a custom bounded caching system requires deep systems programming, low-level CUDA driver knowledge, and memory management expertise.
What it would actually take: Building this requires deep systems and GPU architecture expertise using C++, CUDA Driver/Runtime APIs, and low-level memory management (virtual memory paging, unified memory, pinned host memory, and asynchronous streams). The engineer must handle page faults, cache eviction strategies, and PCI-e bandwidth bottlenecks without crashing compute kernels.
