GNUbg analysis using multi-processors

Pardon my likely going over old ground here. My laptop PC has 2 processors. When I analyze a position using a GNUbg, the Windows Task Manager indicates processor utilization to be roughly 50% (note that for rollouts, utilization is 100%).

This indicates to me that GNUbg is only using one of the two processors to do the analysis. On a work PC with 8 processors, utilization is 12%, indicating that only one of the processors is chugging away.

Looks like the PCs could dedicate a lot more power to the analysis if the program could use more processors.

Is there a way to get GNUbg to use all processors avilable to do its analysis?
