6.1 Introduction

In Chapter 1, we noted that the traditional SAS DATA step always processed data one row at a time using a single compute thread. We said that DS2 was capable of significantly speeding up compute-intensive data manipulation by processing multiple rows of data in parallel. But up to this point, all of our DS2 data programs have also ...
