So far it appears as though my initial suspicion was correct. Ocelot seems to present a single CUDA device interface which can use either the Nvidia driver or the LLVM JIT to run CUDA kernels. The eventual plan is to integrate Ocelot into a runtime system, Harmony, which presents a very high-level interface to parallel resources, and manages multiple backends to keep whatever mix of CPU and GPU cores you have busy. The plan is here (http://code.google.com/p/gpuocelot/wiki/Roadmap http://code.google.com/p/gpuocelot/wiki/Roadmap). Harmony is part of Greg Diamos' (http://gdiamos.net/ http://gdiamos.net/) ongoing PhD thesis work at Georgia Tech.
