How to acknowledge CSC resources
A good place is the acknowledgements at the end of the manuscript. This is a typical one:
The authors wish to acknowledge CSC – IT Center for Science, Finland, for computational resources.
This wording covers both computing time and licenses, and if you've used A LOT of resources, you can add: for generous computational resources.
