Teradata Basics: Parallelism - comment by carrie

Teradata Forum has a category called "Data Modeling" which describes itself as:   Discussion topics on Logical Data Models, Physical Data Models, and Semantic Modeling Building Blocks. 
 
You can find that discussion group at:  http://forums.teradata.com/forum/data-modeling
 
I'd suggest you ask your question there.  Sorry, but  I am not able to help you with this.
 
Thanks, -Carrie
