Carrie,
As per your last comment, "Usually, each AMP will use from 1 to 2 tasks to support it's work on behalf of one request"
If we issue a multi statement request involving selects from different tables or if we issue a join query involving different tables. My assumption regarding the query execution is, The operations can be performed parallely. even though if it is a single request, AMPS can make use of more AWT's (more than 1 to 2) to perform the parallel operations.
I think No of AWT's that requires to run a user request depends on how many parallel operation steps the query/request can be broken into.
Please correct me if i am wrong and help me understand.
