Symmetrical Multi-Processing
Symmetrical Multi-Processing SMP enables all CPUs in the system
simultaneously to service interrupts, access system memory, and perform I/
O operations. If your operating system does not support SMP, the system
adjusts the processing mode to Asymmetrical, meaning only the first CPU
accepts I/O interrupts, while the successive CPUs accept only
interprocessor interrupts.
