Whats in a Name? Terminology and Products?
The proper names for OpenVMS on the various platforms are “OpenVMS VAX”, “OpenVMS Alpha”, and “OpenVMS I64”. Use of “OpenVMS AXP” and of “VAX/VMS” are deprecated. 2-3 General Information The VAX and Alpha terms are largely interchangeably used as the names of platforms, of processor or microprocessor implementations, and of the respective computing architectures. Somewhat confusing to long-time OpenVMS users, Intel IA-32, IA-64, and EM64T, and AMD AMD64 are the names of various computing architectures and of architectural extensions. Only. These are not the names of any implementations, nor of any platforms. Intel Itanium is the name of a family of microprocessor implementations of the Intel IA-64 architecture, as Intel Pentium and Xeon are the names of families of microprocessor implementations of Intel IA-32 and (potentially) of the EM64T extensions.
