I have the Deep/Premium version of HIARCS Chess Explorer Pro, how do I get Deep HIARCS 15 to use more than thread?

By default Deep HIARCS 15.0 uses half the physical cores of the system. We choose this default so that most customers are able to run Deep HIARCS 15 in multiple database tabs without affecting overall system performance. You can change the number of threads used in the Analysis Explorer toolbar. That allows you to set anything from 1 to a maximum of the number of logical cores on your machine. If you want to change the default threads used for Deep HIARCS 15.0 in all database tabs please go to the Preferences->Engines dialog and select Deep HIARCS 15.0 and set the threads to your choice.
Please note HIARCS Chess Explorer Pro also has a load alert which is a red square which appears in the bottom right hand corner of the window, if you see that you can move the mouse pointer over the red square to get info on the system usage of the engines running.
