how to make UrQMD faster?

[YingWANG0909]

Hi developers, UrQMD is much slower than other models in chromo. Is there a way to make it faster if we do not need all the information from the model?

Hi!

Well, it is simply slower than the other models. The issue is not related to chromo. You can try looking up some options to disable or parametrize the QMD part but it depends on what you wanna know from the model.

could you be more specific about which part of the QMD code I could modify if I only want (px, py, pz) of one particular kind of production? thank you very much

I'm not an author of the model, so I don't know exactly what would be a sensitive choice of parameters for your application.

You may need to read the official manual located in 'src/fortran/urqmd-3.4/sources/doc/urqmd-user.pdf' to choose the correct options.
