tuning network for fast VASP calculations
Posted: Tue Dec 15, 2009 12:02 am
Are there any specifics that one should be looking for when one wants to build a cluster tuned for optimal VASP performance?
Questions of the sort:
1. Is low latency super important or high bandwidth?
2. Would Jubmo Frames be helpful? How large of a packet size
etc.
Any comments are very appreciated. I am trying to build a new cluster and anticipate a heavy VASP usage.
