Blender (http://www.blender.org/) source code has function to do that (they needed this to set the default number of threads for renderer). So you could try converting to Pascal the code of "BLI_system_thread_count" function from: https://svn.blender.org/svnroot/bf-blender/trunk/blender/source/blender/blenlib/intern/threads.c Doesn't seem that complicated on 1st look. It's basically appropriate GetSystemInfo call on Windows, sysctl on Mac OS, and sysconf (from Libc) call on most Unixes.
