The following statements run the HPLOGISTIC procedure in symmetric mode on the data appliance:

proc hplogistic data=dataLib.simData; class a b c; model y = a b c x1 x2 x3; performance host = "data_appliance.sas.com" nodes = 10 gridmode = sym; run;

Figure 3.8 shows the results of this analysis.

The "Performance Information" table shows that the execution occurs in symmetric mode on the 24 nodes of the data appliance. In this case, the NODES=10 option in the PERFORMANCE statement is ignored because the number of nodes that are used is determined by the number of nodes across which the data are distributed, as indicated in the following warning message in the SAS log:

WARNING: The NODES=10 option in the PERFORMANCE statement is ignored because you are running alongside the distributed data source DATALIB.simData.DATA. The number of compute nodes is determined by the configuration of the distributed DBMS.
