closeSpecific number of threads?

Hello,
I might have missed this in the paper & supplemental, but is there a way to specify the number of CPU threads to utilise? TIA

Although GRASShopPER steps can be perceived as inseparable elements of the assembly pipeline they were actually implemented independently. The grasshopper executable is merely the script integrating all steps of the method together. To perform given step GRASShopPER invokes appropriate application(s) with its own set of parameters and independently designed parameter naming schema. In order to stick to the "keep it simple and straight" principle we decided to prevent from overwhelming user with a ton of parameters -- we have extracted only those parameters that are relevant for result quality measures tuning. Of course there is always a backdoor to change the default behavior of grasshopper which in this case involves changing the scripts that runs corresponding step:
${REPO}/grasshopper-scripts/run-grasshopper-<step-name>.sh
Two main grasshopper steps namely build and traverse comes with respectively --gpus and --threads options for suppressing number of application threads. It need to be stated, though, that in case of build step the number of threads is strictly connected to the graphics cards to be utilized by the application.
