稀疏网格组合技术提供了一个框架来解决高维数值问题的标准求解器。分层是预处理步骤,便于组合技术所需的通信。派生的分层算法优于基线高达30倍,并实现接近5%的峰值性能。它还显示了高达1 GB的测试数据集的稳定性能。
The sparse grid combination technique provides a framework to solve high dimensional numerical problems with standard solvers. Hierarchization is preprocessing step facilitating the communication needed for the combination technique. The derived hierarchization algorithm outperforms the baseline by up to 30x and achieves close to 5% of peak performance. It also shows stable performance for the tested data sets of up to 1 GB.
