[Pw_forum] Hardware configuration for QE

[Vit]

Dear, QE users!
We are planing to buy new cluster hardware for our lab purposes. The plan is to have 64 physical cores.
I have a bunch of questions regarding this:

1. Which network is preferable? Is Gbit enough? or Infiniband does the best?
2. Is it critical to have fast drives for local tmp filesystem on Gbit ethernet? Or it's considered better to have one common tmp through Infiniband and get rid of HDD's on nodes?
3. What is the amount of RAM recommended per 1 core in a node?

With best regards,
Koroteev Victor
