They have a workload that is entirely dictated by their protein design etc. projects, not by external access to a web app. So "high performance" means doing a single definite task quickly (so they can *proceed to the next run), not scaling to many users and requests. If they need to scale, they first hire protein designers or the like and then they set up some new workstation, probably something different from existing ones for diversification and obsolescence reasons. No cattle.
