Answer / selvaraj
Both AMP and PE are implemented using software and thus the
word Virtual processor. There is no special hardware (like
a special microprocessor) implementation required AMP and
PE to function. This is quite well explained in their
documentation "Introduction to Terdada Warehouse" page 49.
Hope this helps.

Answer / friend
The versatility of the Teradata Database is based on virtual
processors (vprocs)that eliminate dependency on specialized
physical processors. Vprocs are a set
of software processes that run on a node under the Teradata
Parallel Database Extensions (PDE) within the multitasking
environment of the operating
system.

Answer / tdguy
AMPs and PEs are called Vprocs, because they are software
processes and no separate hardware processors. They reside
in the memory of a node.

Vprocs:Virtual process
From PE to AMP (This is the network root via MSP(messege
passing layer),The processing data will store in Disks
(These are Physical disks),Each Amp have too many P.disks,
to migrate these P.disks The Bynet Network maintains
Virtual disks.Thses V.disks will responsible for data
migration.
That y we called this process is Virtual Process(VPROCS).
