In the purely object-parallel approach to multiprocessor rendering, each processor is assigned responsibility to render a subset of the graphics database. When rendering is complete, pixels from the processors must be merged and globally z-bu ered. On an arbitrary multiprocessor interconnection network, the straightforward algorithm for pixel merging requires dA total network bandwidth per fram...

Abstract Water scarcity has become a significant constraint to sustainable development. While the water been widely assessed, its social impacts are infrequently evaluated. Here, we developed framework integrate and climate sensitivity examine vulnerability at prefecture level across China. Results showed that 41% of 301 prefectures were highly stressed 30% sensitive changing climate. We identi...
