RAM/nodes

[sersunzo]

Hi guys,

I need a piece of advice and maybe some of you can help me.
On the basis of your personal experience, what could be a reasonable
RAM per node for a new cluster that will run ab-initio MD (CP2K and/or
CPMD) as well as classical MD (NAMD and/or DL_POLY)?

I suppose, it depend on the particular situation (e.g. number of
atoms), but, in general, which can be a possible range?

Thanks

Alessio
