The Question is:
Compaq has announced that OpenVMS is being ported to Intel's Itanium. A search
for "AMD" using the "Search OpenVMS" turned up no results. Does that mean that
OpenVMS will not be able to run on AMD (Hammer or Sledgehammer which also are
64 bit archs)?
The Answer is :
At present, there are two platform architectures with OpenVMS support,
and exactly one port of OpenVMS announced: VAX and Alpha have support,
and a port of OpenVMS to the Intel Itanium Processor Family Architecture
is presently underway.
Compaq has not announced any plans to port OpenVMS to any other platform
The bit-width of the addressing of a particular platform architecture
is only one of many aspect and many considerations of a platform port
of an operating system. Details of the page tables, page protections,
memory virtualization capabilities, instruction set, and a host of other
details are all considerations.
For details of the Intel Itanium and the AMD processor architectures,
please visit the website(s) of the microprocessor vendors.
See the "Compaq & Intel" enterprise initiative link at the OpenVMS website, as well.
