[in] | n_partitions | Macro variable (set via the IRM macrovarload facility) specifying the number of requested partitions. Valid options: MAX, AUTO, <N>. See below for details. |
[in] | ds_in | Input table to be partitioned |
[out] | ds_out_cardinality | Output IRM cardinality table |
This node sets the number of data partitions for enabling IRM parallel processing:
, the cardinality is set to the specified value
In addition the following macro utilities are called:
Macro name | Description | Further information |
---|---|---|
irm_session_prepare | Reads RUN_OPTION table and sets logging options | irm_session_prepare.sas |
irm_session_cleanup | Removes all non-IRM WORK datasets/views and deletes all user-created macro variables from workspace session | irm_session_cleanup.sas |
