发现一个问题 Windows 10 和 Windows11 CPU调度使用不一样. 11 明显好 如图
| 计算时间 单位 秒 | A: Windows 10 8核计算 | B: Windows 11 8核计算 |
| 默认参数 | 530 | 388 |

mpiexec -np $NCPU -affinity -affinity_layout Spread:L "$SOLVER" i=$INPUT memory=$MEMORY
mpiexec -np 8 -affinity -affinity_layout Spread:L "C:\LSDYNA\program\ls-dyna_mpp_s_R12.1_190-gadfcdf9018_winx64_ifort170_msmpi\ls-dyna_mpp_s_R12.1_190-gadfcdf9018_winx64_ifort170_msmpi.exe" i=C:\DT\test1\crush_tube.key memory=20m
在 Windows 10 电脑上 加入一个参数 就改善 提速 1.39倍
