• 16:18, 5 April 2022 Kaltakm talk contribs deleted page Memory requirements of low-scaling GW and RPA algorithms (content was: " The cubic scaling space-time RPA as well as GW algorithm require considerably more memory than the correspondong quartic-scaling implementations, two Green's functions <math>G({\bf r,r'},i\tau_n)</math> have to be stored in real-space. To reduce the memory overhead, VASP exploits Fast Fourier Transformations (FFT) to avoid storage of the matrices on the (larger) real space grid, on the one hand. The precision of the FFT can be selected with {{TAG|PRECFOCK}}, where usually the...")
