[CP2K-user] [CP2K:19921] Geometric optimization hangs with no error.

[Max Nishibuchi]

Thank you very much Matthias, I was able to get the calculation to converge 
using one of the recent CPU docker images. 

However, I'm still not entirely sure how to go about diagnosing the issue 
with the GPU image. Is PRINT_LEVEL the only way to adjust how much 
information is written/output by the program? 

Kind regards,

Max
