 for symmetric multiprocessing
From The Free On-line Dictionary of Computing (30 December 2018) :

  symmetric multiprocessing
  symmetric multiprocessor
      (SMP) Two or more similar processors connected
     via a high-{bandwidth link and managed by one operating
     system, where each processor has equal access to I/O devices.
     This is in contrast to the "{compute server" kind of
     parallel processor where a front-end processor handles all
     I/O to disks, terminals and local area network etc.
     The processors are treated more or less equally, with
     application programs able to run on any or perhaps all
     processors in the system, interchangeably, at the operating
     system's discretion.  Simple MP usually involves assigning
     each processor to a fixed task (such as managing the file
     system), reserving the single main CPU for general tasks.
     OS/2 currently supports so-called HMP (Hybrid
     Multiprocessing), which provides some elements of symmetric
     multiprocessing, using add-on IBM software called MP/2.  OS/2
     SMP was planned for release in late 1993.
