Running in Asymmetric Mode on One Appliance

You can switch to running the HPLOGISTIC procedure in asymmetric mode by specifying the GRIDMODE=ASYM option in the PERFORMANCE statement as follows:

proc hplogistic data=dataLib.simData;
   class a b c;
   model y = a b c x1 x2 x3;
   performance host        = ""
               nodes       = 10
               gridmode    = asym;

Figure 3.8 shows the Performance Information table.

Performance Information
Host Node
Execution Mode Distributed
Grid Mode Asymmetric
Number of Compute Nodes 10
Number of Threads per Node 24

You can see that now the grid mode is asymmetric. Furthermore, the NODES=10 option that you specified in the PERFORMANCE statement is honored. The data are moved in parallel from the 24 nodes on which the data are stored to the 10 nodes on which the execution occurs. The numeric results are not reproduced here, but they agree with the previous analyses.
