Is there an API that would allow me to discover the availability of

of some computationally intense code.
Anyone know of such an API, particularly one that is someone
platform-independent?
There are a number of APIs that'll return the number of processors.
The most basic BSD-level one is the hw.ncpu sysctl, which you can
access either by name or by number (CTL_HW/HW_NCPU).
I'm not aware of any cross-platform API to get this information, but
if anyone else knows of one I'd be interested in hearing about it.
sysconf() is the POSIX way of answering this question.
