symmetrical multiprocessing

   A multiprocessing design that assigns a task to a processor in response to system load as the application starts running. This design makes for a much more flexible system than asymmetrical multiprocessing, in which the programmer matches a specific task to a certain processor while writing the program.
   In symmetrical multiprocessing, the overall workload is shared by all processors in the system; system performance increases as more processors are added into the system. The drawback is that symmetrical multiprocessing operating systems are much harder to design than asymmetrical multiprocessing operating systems.
