Teradata recommended combination is 1PE for 4 AMPs.

one of the tasks of PE being

-Compiling and dispatching processing instructions over the communication layer to the other parts of the system

Any particular PE might be supporting the requests from more than one AMP( If you are looking at your PMON, click on one PE number, you could see this...)

In your case, particular AMP may be idle,PE might be catering to the needs of the other AMPs associated to it.

I doubt that this indicates going into 'flow control mode'
