In my university we used COMSOL Multiphysics (https://en.wikipedia.org/wiki/COMSOL_Multiphysics). It is 'AllSIM' software and in coincidence was used for very similar case as in the article.

"CERN purchases multi-user licenses for COMSOL Multiphysics"

https://www.comsol.com/press/news/article/821/

"Another factor that was attractive was the fact that a single network license allows CERN to run a COMSOL job on any number of cores or a compute cluster."

And their "Floating Network License" allows use across an entire network, but not off that network: https://uk.comsol.com/products/licensing

True, that could well be the software they're refering to. The reason I suspected that it may be Allegro AMS Simulator was a combination of it being listed on the CERN Engineering Software DB[1] and the product name.

Yeah, I would imagine CERN uses a lot of different packages. Indeed, they'd probably be mad not to run serious simulations across multiple systems to sanity check.. :)
