GPU acceleration of non-equilibrium Green’s function calculation using OpenACC and CUDA FORTRAN

2026 · The International Journal of High Performance Computing Applications

The numerical solution of the Kadanoff-Baym nonlinear integro-differential equations, which yields the non-equilibrium Green’s functions (NEGFs) of quantum many-body systems, poses significant computational challenges due to its high computational complexity. In this work, we present …
