very interesting multiprocessing multicore examples not just for Houdini, in general

you can create a bunch of guide curves, then delete half of them, then into the clump node, you can plug all te guides into the first input and the half into the second input,
play with the number of deleted curves to get the look you desire.

(you should check check fabio hair system,)

you might need to recreate the values, check fabio hair system, they do that in their network, to assist if some one brings curves from other software,
