CMP
(1) (CMP Media LLC, Manhasset, NY, www.cmp.com) Part of United Business Media, CMP is a leading integrated media company that offers a wide variety of publications and services in the information technology, electronics and healthcare fields. CMP properties include more than 45 print publications and 90 Web sites. In 1994, CMP was the first to establish Web sites for its print publications, and its TechWeb site offered the first online technology news service.
Founded in 1971 by Gerard and Lilo Leeds, CMP was acquired by U.K.-based United News and Media, which later changed its name to United Business Media (UBM).
In 2008, UBM eliminated the CMP name and restructured CMP into four business units reporting directly, each with its own CEO: TechWeb, Everything Channel, TechInsights and Think Services. TechWeb was formerly the Business Technology Group; Everything Channel was CMP Channel; TechInsights was the Electronics Group, and Think Services comprises the Game, Dr. Dobb's and International Customer Management Groups.

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