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 = "data_appliance.sas.com"
nodes = 10
gridmode = asym;
run;
Figure 3.8 shows the “Performance Information” table.
Figure 3.8: Alongside Teradata Execution in Asymmetric Mode
| Performance Information | |
|---|---|
| Host Node | data_appliance.sas.com |
| 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.
