How the SAS Scoring Accelerator for Aster nCluster Works
Using SAS Enterprise
Miner, you can generate SAS DATA step code that contains scoring functions.
The SAS Scoring Accelerator for Aster nCluster takes the SAS DATA step code, the associated property file
that contains model inputs and outputs, and a catalog of user-defined
formats, and deploys, or publishes, them to the Aster nCluster database as scoring files. Inside the
Aster nCluster database, a
SAS SQL/MR function is installed and used to execute the scoring model.
Figure 1.1 illustrates this process.

1Install the components that are necessary for in-database processing
in the Aster nCluster database.
For more information,
see Deployed Components for In-Database Processing.
2Use SAS Enterprise Miner to create a scoring model, and use the Score
Code Export node to export files that are used to create the scoring
files to a score output directory.
For more information,
see Exporting the Scoring Model Files from SAS Enterprise Miner.
3Start SAS 9.2 and run the SAS publishing macros, which create the
scoring files that are needed to execute the scoring model and publish
those files to the Aster nCluster
database.
For more information,
see Publishing the Scoring Files.
4After the scoring files are created, they are available for use by
a SAS SQL/MR function in the same way that the Aster nCluster SQL/MR functions are used.
