Hi

This is system dependent. On POSIX systems, you should be able to use
sysconf(_SC_NPROCESSORS_ONLN). I think that this should work for Mac OS X,
Linux, Solaris and FreeBSD. The last time that I needed this for HP-UX, it
wasn't available, and I had to use some other system functions. I don't know
what the equivalent is on Windows.

A+
