But unless programmers find new ways to keep all the transistors busy on calculations at the same time, the potential increase in computing speed is wasted.
"This is why GPUs are designed to run hundreds of calculations at the same time very efficiently," says Steve Scott, Tesla chief technology officer at Nvidia.
However, it is not known how to use it so far, and it greatly increases the amount of computation in multidimensional calculations at the same time. .
Four such trajectories, generated at T = 0.5 and different initial states, are shown in Fig. 2 (see panel (c)) along with inherent structure calculations at the same T.
We are, in essence, performing two coupled CYK calculations at the same time.
The extent of the delocalization observed in the AIPIMD simulations is similar to the spreading observed in the HQTST calculations at the same temperature.
Solvation effects on the structures were then finally taken into account by performing self-consistent reaction field (SCRF) calculations using the CPCM polarisable conductor calculation model with benzene set as the solvent.[ 89, 90] All optimised geometries were confirmed as energy minima with no imaginary frequencies using frequency calculations at the same level of theory.
Because the expansion expression of (varphi (varepsilon^{2})) is too complicated, in the following discussions, we may set (a=-frac{1}{c^{2}}) to simplify our calculation process at the same time, that is, (lambda_{1}=c(1}=c).
Thus, our aim is to explore their electronic and spectroscopic properties on the basis of the DFT quantum chemical calculations, and at the same time, we are interested to make an idea on the parameters influencing the photovoltaic efficiency toward a better understanding of the structure property relationships.
For sake of consistency, these calculations were performed at the same level of theory of present calculations (PAW/LDA), with same cutoff, reduced k-point sampling (43Γ- centered), and force convergence threshold which is reduced up to 0.05 eV/Å.
