[CP2K-user] [CP2K:20929] Re: Slow AIMD Calculations and Memory Issues

[Jawad Elhamdaoui]

Dear Frederick,

Thank you for your prompt response.

Please find attached the output file. Regarding the input, I used the same
file I uploaded earlier, but I commented out the cell part to restart the
calculation and add the restart part.

Please let me know if you need any further details.

Best regards

Jawad
