The OPTMILP Option Tuner

This example demonstrates how to run the tuner in distributed mode. The example is similar to Example 14.2. The only difference between single-machine and distributed mode is that the PERFORMANCE statement specifies the number of threads and nodes to be used. The following statement changes the operating mode to distributed:

   /* set the numbers of nodes and threads and get performance details */
   performance nodes=5 nthreads=4 details;

The performance information and procedure task timing tables are displayed in Output 14.3.1. The NODES=5 and NTHREADS=4 options in the PERFORMANCE statement cause the tuner to run in distributed mode, where each computer node processes up to four threads simultaneously.
