The HPDS2 Procedure
The HPDS2 procedure provides a vehicle for parallel execution of DS2 code in a distributed computing environment. The following list summarizes the basic features of the HPDS2 procedure:
-
provides the ability to execute DS2 code in parallel
-
enables DS2 code to be executed on a local client machine (single-machine mode) or on multiple machines in a distributed computing environment (distributed mode)
-
enables control of the level of parallelism per execution node and the number of nodes to engage
-
performs a syntax check of the DS2 code on the local client machine before sending it to the distributed computing environment for execution
-
manages data migration to the location of execution and movement back to the client machine as needed
Because the HPDS2 procedure is a high-performance analytical procedure, it also does the following:
-
enables you to run in distributed mode on a cluster of machines that distribute the data and the computations
-
enables you to run in single-machine mode on the server where SAS is installed
-
exploits all the available cores and concurrent threads, regardless of execution mode
