Hi,

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

Thanks
Thiru

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.
