Porting marine ecosystem model spin-up transport matrices GPUs
2014/12/17
We have ported an implementation of the spin-up for marine ecosystem models based on transport matrices to graphics processing units (GPUs). The original implementation was designed for distributed-me...
A semi-analytical solution to accelerate spin-up of a coupled carbon and nitrogen land model to steady state
The spin model The steady state coupling Ecosystems Carbon transfer
2014/12/10
The spin-up of land models to steady state of coupled carbon–nitrogen processes is computationally so costly that it becomes a bottleneck issue for global analysis. In this study, we introduced a semi...
