(1) Formerly CMP Media, CMP was acquired by United News and Media in 1999. See UBM.
(2) (Cellular MultiProcessing) An earlier multiprocessing architecture for Intel CPUs from Unisys. Providing up to 32 processors that are crossbar connected to 64GB of memory and 96 PCI cards, a CMP system provided mainframe-like architecture using Intel CPUs. CMP supported Windows NT and 2000 Server, AIX, NetWare and UnixWare and could run as one large SMP system or multiple systems with different operating systems. See SMP.

A CMP subpod contained four x86 or Itanium CPUs, which connected through a third-level memory cache to the crossbar. Each crossbar supported two subpods, two direct I/O bridges (DIBs) and connected to four memory storage units (MSUs). This diagram shows the four crossbars and all eight subpods that made up a complete CMP system.
