Hi All,

Why a Parsing Engine(PE) and Access Module Processor(AMP) called as Virtual Processors.

Hi,

PE and AMP are set of software processes (we can configure their number based on requirement)..so we call them as Virtual Processors.

Its basically a process running on the underlying linux (or windows, whatever).

Its not a Virtual Processor in Server technoloy terms, its not a division of a Physical CPU as you would find on Large Unix servers.

I think in the distant past it was actually a physical thing, but not now.

You're correct, in Teradata Version 1 every AMP/PE was a single proprietary server with Memory, CPU, disks and Operating System. In V2 it was rewritten as software only, now those processors are only virtual.
