Linux: 64-bit support, mmap, CUDA, everything is happy.
OS X: CUDA does not support 64-bit. ARGH.
Windows: VS2008 Express Edition doesn't have 64-bit compilers by default, Windows doesn't have mmap support!

*irritated*

The initial release may be Linux only for full support. This sucks, but I had no idea I'd run into these issues going to Windows/OS X.

Windows: Use a recent Windows SDK, Windows has VirtualAlloc instead of mmap (this might be useful, too)

Most interesting. Thank you, I will look into that!

As I'm a proud owner of a legal MSDNAA account (hehe-he) I'm pretty lucky. Oh, and x64 C++-programming on Windows is just as easy as x86 if you never programmed anything on a *nix machine before
