[CP2K:4919] CP2K - new version release - 2.4

[Teodoro Laino]

Stephen,

you can contact Juerg Hutter for such requests. He is the project leader.

In any case, cp2k is released under GPL and there is no fee charged whatsoever (this means companies, universities and govs can download it for free).

You are allowed to sell copies or the even the usage of the program commercially, but only under the terms of the GNU GPL. 
Thus, for instance, you must make the source code available to the users of the program as described in the GPL, and they must be allowed to redistribute and modify it as described in the GPL. It’s up to them whether they are willing to pay something to you for a software that they can freely access.

Having said that there is no permission that you need to ask, neither for selling them time on your machines (this is pretty obvious) nor for selling them the usage or even (potentially) the code itself.

Teo
