“…His RRTMG longwave radiation scheme (RRTMG_LW) achieves an acceleration speed of 69× when implemented on a NVIDIA GTX 680 GPU [20] and 127× on a single K40 GPU [21]. Y. Wang, et al developed a GPU version of RRTMG_LW that was implemented in CUDA Fortran and integrated into CAS-ESM [22]- [24].…”

Govett et al, (2017) used Open Accelerator (OpenACC) directives to port the dynamics of NIM to the GPU and achieved 2.5x acceleration.…”

“…For the Princeton Ocean Model, Xu et al, (2015) use CUDA C to carry out heterogeneous porting and optimization, the performance of gpu-POM v1.0 on four GPUs is comparable to that on 408 standard Intel Xeon X5670 CPU cores. In terms of climate system model, Wang et al, (2021c) and Wang et al, (2021b) porting scheme is the most complex, but its computational performance is the highest (Mielikainen et al, 2012b;Wahib and Maruyama, 2013;Xu et al, 2015).…”

“…SHDOM is almost 2 orders of magnitude more computationally efficient than Monte Carlo on CPU for multi-angle imagery (Pincus and Evans, 2009). Monte Carlo solvers specialized for 3D atmospheric scattering problems have been slow to adopt a GPU-based computation, which is anticipated to give a reduction in the wall time of between 1 and 2 orders of magnitude (Efremenko et al, 2014;Ramon et al, 2019;Wang et al, 2021;Lee et al, 2022), thereby making Monte Carlo competitive against SHDOM in the future.…”
