请问各位老师在使用Gromacs计算分子动力学时出现下面错误,请问是什么原因呢,该怎么解决呢?

starting mdrun ''
30000000 steps,  30000.0 ps.
step 4800: timed with pme grid 84 84 84, coulomb cutoff 1.000: 212.6 M-cycles
step 5000: timed with pme grid 72 72 72, coulomb cutoff 1.116: 562.1 M-cycles

凡是GPU跑有问题时,改用纯CPU跑再试看看情况
光给个mdp几乎毫无用处,绝大多数情况问题都不是来自于mdp


并且别写fourierspacing        = 0.16这种网上流传的多余且对精度有害的设置
