[CP2K-user] [CP2K:20922] Slow AIMD Calculations and Memory Issues

[Jawad Elhamdaoui]

Dear CP2K Community,

I am facing issues with my AIMD calculations. My *system size is *162 
atoms, and I run on an *HPC setup of* 500 CPUs. Each step takes ~15 
minutes, and I also encounter out-of-memory errors.

I suspect the issues might be due to input settings or parallelization 
inefficiencies. Could you please advise how to optimize performance and 
memory usage for a system of this size?

I appreciate your help!

  Best regards,

Jawad
