SAS Data Integration
Studio uses a set of macros to enable parallel processing. You can
enable these macros by doing one of the following:
-
selecting
YES in the
Enable parallel processing macros option on the
Options tab of the properties
window for a job.
-
including a Loop transformation
in a job.
When you
enable the parallel-processing option for a job, macros are generated
at the top of the job code with comments. These macros enable you
to create your own transformations or code in order to use parallel
processing.
When you
include a Loop transformation in a job, the transformation generates
the necessary macros to use sequential execution, symmetric multiprocessing
(SMP) execution, or execution on a grid computing network.
No special
software or metadata is required to enable parallel processing on
SMP servers. Grid options can be enabled for a job even when the grid
software has not been configured and licensed. However, SAS Data Integration
Studio does not generate grid-enabled code for the job in this case.
It generates code that is appropriate for SMP on the SAS Application
Server.
The
following table describes the prerequisites that are required to enable
parallel processing for SAS Data Integration Studio jobs. For details
about these prerequisites, see the appropriate section in the documentation
mentioned below.
Prerequisites for Parallel Processing of SAS Data Integration
Studio Jobs
Computers Used for Parallel Processing
|
|
SMP machine with one or more processors
|
Specify a SAS®9 Workspace
server in the metadata for the default for SAS Data Integration Studio.
See the “Specifying Metadata for the Default SAS Application
Server” topic in SAS Data Integration Studio Help.

Specify an appropriate SAS Metadata
Server to get the latest metadata object for a grid server. See the
SAS Data Integration Studio chapter in the SAS Intelligence
Platform: Desktop Application Administration Guide.
Specify an appropriate
SAS®9 Workspace Server in the metadata for the default.
Grid software must
be licensed.
Define or add a grid server component to the metadata that points
to the grid server installation. The controlling server machine must
have both a grid server definition and a SAS Workspace Server definition
as a minimum to be able to run your machines in a grid. It is recommended
that you also have the SAS Metadata Server component accessible to
the server definition where your grid machines are located.
Install Platform Computing
software to handle workload management for the grid.

Note: For additional
information about these requirements, see the grid chapter in
SAS Intelligence Platform: Application Server Administration Guide.
