Steve,

To detect the number of CPUs available on the system on Linux, you can use:

#include <unistd.h>

sysconf (_SC_NPROCESSORS_ONLN);

That returns the number of processors, if the value -1 is returned, it means
that the _SC_NPROCESSORS_ONLN query is not supported in that operating
system/kernel combination (should be supported for Linux as far as the eye can
see though).

But if you get -1, then another operating system specific hack can be used.
