The HPSAMPLE Procedure
The HPSAMPLE procedure is a high-performance procedure that performs either simple random sampling or stratified sampling. The HPSAMPLE procedure runs in either single-machine mode or distributed mode. Note: Distributed mode requires SAS High-Performance Server Distributed Mode .
The HPSAMPLE procedure creates the following:
-
one output data set, which contains the sample data set
-
one performance table, which contains performance information
-
one frequency table, which contains the frequency information for the population and sample
Because the HPSAMPLE 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 (currently HPSAMPLE is only using a single thread)
