As a part of a research project, I perform numerical simulations in my computer, and initially I could not work with bigger systems due to lack of computer memory.
A friend from college had a spare RAM module, which was compatible with my computer. He gave it to me (for free), and I would return it when this project would be over.
This enabled me to work with larger systems. We got some new results, and we are in the process of writing a paper. How can I acknowledge my friend? I don't know if it is a standard practice.
Also, I had once told my research supervisor that I obtained this RAM module from a friend, but did not say that I want to acknowledge him if we write a paper (because back then I did not even know if I would get publishable results). How should I ask my supervisor about this? My supervisor is a friendly person.
My friend is a classmate, but not a part of my research group, and did not contribute to the research. But I feel that I should acknowledge his help, because without it I would not be able to run these simulations. Something like "I acknowledge X for providing computational facilities" might seem confusing.
