1 State Key Laboratory of Coal Combustion, School of Energy & Power Engineering, Huazhong University of Science and Technology CPM code 开发记录 Wed, Sep,9, 2015 毕晟

2 2 State Key Laboratory of Coal Combustion, School of Energy & Power Engineering, Huazhong University of Science and Technology CPM code 开发记录 1,image_pot() 采用 MPI 通讯的方式,计算 phi_r ,和 phi_k. 放弃 MPI_Bcast 的方式获取 phi_k 。 2,green() 也采用 MPI 通讯计算的方式,沿 Z 方向划分区域到每个 core ,然 后采用 MPI_Bcast 来得到全部 phi_c 。 3, 测试了 gather_f_bsplines(), 并与 eforce() 对比。

3 3 State Key Laboratory of Coal Combustion, School of Energy & Power Engineering, Huazhong University of Science and Technology Phi_C 平板测试 与理论值保证 5 位有效 数字 相对误差 10e-6

4 4 State Key Laboratory of Coal Combustion, School of Energy & Power Engineering, Huazhong University of Science and Technology 点电荷受力测试 采用 eforce() 方式计算受力,电荷放在 fft grid 上。

5 5 State Key Laboratory of Coal Combustion, School of Energy & Power Engineering, Huazhong University of Science and Technology 点电荷受力测试 采用 eforce() 方式计算受力,电荷不放在 fft grid 上。

6 6 State Key Laboratory of Coal Combustion, School of Energy & Power Engineering, Huazhong University of Science and Technology 点电荷受力测试 采用 gather_f_bsplines() 方式,pme-order=6, 计算受力,电荷放在 fft grid 上。

7 7 State Key Laboratory of Coal Combustion, School of Energy & Power Engineering, Huazhong University of Science and Technology 速度测试 机器: Einstein 节点 1 提交一个 case , 8nodes , 2.787ns/day 提交两个 case ,一共 16nodes , 2.56ns/day 提交 4 个 case , 32nodes , 1.75ns/day
