This document describes the functioning of multithreading within SAS Visual Data Mining and Machine Learning (Viya 8.1) procedures, specifically FACTMAC, FOREST, GRADBOOST, NNET, SVMACHINE, TEXTMINE, and TMSCORE. It explains how computational tasks are organized into threads and how parallel data...
The DATA step is a fundamental component of SAS programming, enabling data manipulation and transformation. In the SAS Viya environment, the DATA step can execute not only in a traditional SAS session but also on the CAS server, leveraging distributed processing for increased performance.
