I am afraid that:
high cutoff + many k-points + hybrid functionals + PAW = an enormous amount of time

I did dft calculations with the hybrid HSE functional. The mail part of the input file is here:

In order to provide the necessary resources (primarily RAM), I set a walltime of 12 hours (the maximum available). During this time, only self-consistent calculations were made.... the output file ended with this:

Please write if possible:
1) use the obtained result (for example, charge-density.dat) to run the same calculation? How to do this and will it help to perform the calculation with the same resources (140 cores, 5 TB RAM)? 2) simplify the input file to speed up the calculation (or reduce the required resources)

Thanks in advance,
Alex
