The number of threads can be controlled using the command <Maximum_Number_of_Threads>

<Simulation_Parameter>
  ...
  <Maximum_Number_of_Threads>12</Maximum_Number_of_Threads>
  ...
</Simulation_Parameter>

In the case where a combined Temperature-Voltage sweep is used, there are two levels of parallelization. The first is at the level of the command <Threads> in the <SweepParameters> section.

<SweepParameters>   
  <SweepType>Temperature-Voltage</SweepType>
  ...
 <Threads>6</Threads> <!-- Parallelization for Temperature-Voltage sweep -->
 </SweepParameters>

The second level of parallelization occurs in the <Simulation_Parameter> section:

<Simulation_Parameter>
  ...
  <Maximum_Number_of_Threads>2</Maximum_Number_of_Threads>
  ...
</Simulation_Parameter>

In this example, the total number of threads will be <Threads>* <Maximum_Number_of_Threads> = 6*2 = 12.
