So, CUDA Toolkit 2.2 along with an updated CUDA SDK and drivers is released. How does it affect to folding efficiency?
Can protein folding benefit from ver 2.2 new features?

CUDA 2.2. has a new feature called "zero copy" memory access. It allows GT200 GPUs as well as MCP79 (?) integrated chipsets to access host memory directly over the PCI-e bus. This may in some cases be useful to speed up a computation because a some copying overhead from and to the GPU memory may be saved.

However to use this new feature, some program code may have to be redesigned. And it wouldn't boost G80 or G92 GPU performance at all because these GPUs lack the hardware support for this feature.
