I am using Cuda 3.1. Boot your SL in 64 bits, then go to /Developer/GPU Computing/C and 'make'. Everything compiled and all bins in "/Developer/GPU Computing/C/bin/darwin/release" are, e.g.,
volumeRender: Mach-O 64-bit executable x86_64 Doing 'file /usr/local/cuda/lib/*' and all libs there are now universal, e.g.: /usr/local/cuda/lib/libcublas.dylib: Mach-O universal binary with 2 architectures /usr/local/cuda/lib/libcublas.dylib (for architecture x86_64): Mach-O 64-bit dynamically linked shared library x86_64 /usr/local/cuda/lib/libcublas.dylib (for architecture i386): Mach-O dynamically linked shared library i386 So, I believe now that finally Cuda lib and API for Mac are full 64 bits (although 'file /usr/local/cuda/bin/*' are all still i386). Now, after a couple of months, I will give another try to pycuda and pyopencl.
