Hey, I just downloaded DevCenter using the first link you provided, and uncompressed in my computer. A folder with name DevCenter has been created, and there are four elements in that folder: CHANGELOG.md, DevCenter, examples (a folder) and README.md. (285.86 or later for Windows, 290.10 for Linux and the CUDA 4.0 driver extension for Mac). For the Mac, the driver extension module supplied with CUDA 4.0 or later will need to be installed. Driver versions beginning with 285.53 include very large speedup to OptiX compile times.
