You have to accept the license.

Parallel run

CPLEX utilizes OpenMP system (parallelization through many processor cores in one machine). You can restrict the number of cores by set up of system variable OMP_NUM_THREADS, for example:

export OMP_NUM_THREADS=$PBS_NUM_PPN

which uses the number of processors granted by planning system. You can also restrict the number of cores directly in the program by set up a proper directive in .mod file:

execute{
  cplex.threads = XXX;
}
