ab initio MD - necessary requirements

[emerson p l]

Dear friends,

I'm starting to study ab initio MD, and I have a doubt as to whether it is viable to run Car–Parrinello molecular dynamics with the computational resources I have.

I saw an example with 64 water molecules, on average, how much RAM would be needed to run a system of this size on CP2K? What would be the number of threads needed?

Thanks in advance.

Best, 

Emerson.
