Description
An experimental open-source CUDA SDK with RAM backing and a bounded VRAM cache. The recorded RTX 3070 demo processes 11.999 GiB of matrix data on an 8 GiB GPU. Includes a Windows build, C API example and local validation. Explicit integration required.

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.
