Re: PDE

PDE (Parallel Database Extensions) runs on top of the OS, it's a kind of emulation of the old V1 Teradata Operating System (TOS).

Thus PDE is the foundation of Teradata, it may be started without starting TD.

On top of PDE runs the TPA (Trusted Parallel Application), i.e. the VProcs (mainly AMPs and PEs), they communicate through the BYNET software within a node and the BYNET hardware between nodes.
