The HPSPLIT Procedure

Memory Considerations

PROC HPSPLIT is built for high-performance computing. As a result, it does not create utility files but rather stores all the data in memory. Data sets that have a large number of variables and few observations, particularly if they have a large number of target levels, can cause PROC HPSPLIT to run out of memory. One way to overcome this is to give SAS more memory to use. Another way to deal with this is to use fewer threads.
