Are there applications that can crunch numbers without an OS
Applications that would boot straight from boot media without needing to be run from an OS. Something like memtest86 but for crunching numbers.

If there are not, why not?

WOuld this lead to better performance, leaving the OS behind?

Or would there be no difference, basically replacing system calls with function calls?
