How to use more PolyUMod cores?

Hi, everyone! I have 4 license available for PolyUMod-Dyna, but it only check out one PolyUMod license. Where to set that I can use more PolyUMod CPUs/License? I want use more! 

To clarify my question——It is the computational efficiency. I want to use more CPUs about PolyUMod, not more CPUs about dyna. Because when I didn't use the material in PolyUMod, the model causes 3 days to calculate, while when I used the material in PolyUMod, it causes 1524 days to calculate. The time is so strange. I think the key point is that I can just only use 1 core in PolyUMod. SO I want to use 4 cores about PolyUMod simultaneously to increase computational efficiency. How to do THIS?? 

Thank you for your help!!
