0 - 3 of 3 tags for set processing

Hi,
 
Can anybody tell me what is an all-amp operation from the following:
1- Set Processing
2- Row Processing

Is there a way to generate a surrogate key dynamically using set processing rather than record level processing? We have a large amount of records in the source which we need to generate a unique identifier in the EDW for and cursor level processing seems to be quite slow in generating surrogate keys for this volume of data.
