CUDA Developers: Fermi Tuning Guide and CUDA Programming Guide Updated
NVIDIA has updated the Fermi tuning guide (version 1.2) and the CUDA C programming guide (version 3.1.1).
The version 1.2 of the Fermi tuning guide adds this advice:
For CUDA Driver API applications, the use of 32-bit device code within a 64-bit host application is no longer recommended, as support for this mixed-bitness mode will be removed in CUDA 3.2. (Note that the CUDA Runtime API already requires that the device code and host code have matching bitness.)
