March 22, 2021 at 2:55 pmmonipmfSubscriberHi everyone,nwe are planning to buy a little cluster for working on 'heavy' projects but I came accross some doubts and it would be great if someone could give me a hand.nI?m used to work on a Windows workstation and, assuming that this cluster will run on Linux (on which I have very little experience), which skills do I have to acquire to being able to work efficiently on that environment?nAnd how the job management will differ from a Windows workstation in terms of GUI, real-time monitor and so on?n nMoreover, how can one estimate the hardware effort required by a project?nWhich are the indicators that can show how many cores and RAM is better to have to solve efficiently a particular model?n n Thanks in advance,nMon

March 23, 2021 at 10:10 amRobAnsys EmployeeWhich solver are you wanting to run? For CFD we may want many cores and a fair amount of RAM: Mechanical doesn't scale as well (it's still pretty good) so you may want fewer cores but more RAM and SSD drives. n
