started to learn cp2k. But some troubles were encountered in this process. For
example, if the spectrum is calculated on a node with a running memory of 250G, the
remaining memory is quite tight when proceeding to the "TDDFPT
WAVEFUNCTION OPTIMIZATION" step. Due to the huge size of my system (with
small HOMO-LUMO gap), I had to set more nstates in the inp file. In addition to
calculating more excited states, does the inp file have some settings that can
be optimized? I look forward to and thank you for your advice.</span></p><p class="MsoNormal"><span lang="EN-US"> Remarks: The CPU version information is 96 Intel(R) Xeon(R) Platinum 8175M CPU @ 2.50GHz. The disk space is 4T.</span></p></blockquote>
