So far what I have gathered is this:
The correct answer depends on the processor architecture, of course, but
for example in most Intel-based architectures there's a physical controller
chip named APIC (Advanced Programmable Interrupt Controller) that's used
for, among other things, wake up additional processors/cores and make them
run specified code.
What I still can't figure out is how exactly you tell the APIC to do that.
