[QE-users] Quantum Espresso on Amazon Web Services

[Giovanni Pizzi]

Hi,
Give a look to this article:
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/t2-credits-baseline-concepts.html

It’s possible that you have one of these VMs, that on average deliver only a low (even only down to 5%) performance than the actual CPU performance (it might seem fast at the first run, if you didn’t run anything, but the algorithm of CPU credits will make runs be slow, eventually).

Also, crashes might be due to limited RAM.

HTH,

Giovanni

Dear QE users and devalopers
I'm running QE on Amazon Web Services (AWS) and I see that the run times are very bad compared to other systems that I use and I also encountered crashes which I cannot understand the reason for them. Does anyone work on AWS and know something about the performance and special compilation issues?
Thank you
