What are the supported versions of CUDA? According to the documentation, it's correct for [CUDA 6.0](http://docs.nvidia.com/cuda/cuda-runtime-api/api-sync-behavior.html#api-sync-behavior__memcpy-sync) and [CUDA 4.1](http://developer.download.nvidia.com/compute/cuda/4_1/rel/toolkit/docs/online/sync_async.html#MemcpyAsynchronousBehavior) (case 3 is ours). For other versions I'd need to consult [the archive](https://developer.nvidia.com/cuda-toolkit-archive).
