[求助] 请教大家,为什么FFT planing... 然后计算退出?

如下的输出结果,不知道是不是因为内存不够的原因,FFT这步过不去,体系算的时候加了soc,K-mesh9*9*1,麻烦大家了

这个是OUTCAR最后的几行:
k-point 79 :  -.3333-.11110.0000  plane waves:  265930
k-point 80 :  -.2222-.11110.0000  plane waves:  266036
k-point 81 :  -.1111-.11110.0000  plane waves:  265954

maximum and minimum number of plane-waves per node :  266088 265862

maximum number of plane-waves:  266088
maximal index in each direction:
   IXMAX= 31   IYMAX= 31   IZMAX= 38
   IXMIN=-31   IYMIN=-31   IZMIN=-38

WARNING: aliasing errors must be expected set NGX to 126 to avoid them
WARNING: aliasing errors must be expected set NGY to 126 to avoid them
WARNING: aliasing errors must be expected set NGZ to 154 to avoid them
aliasing errors are usually negligible using standard VASP settings
and one can safely disregard these warnings

serial   3D FFT for wavefunctions
parallel 3D FFT for charge:
    minimum data exchange during FFTs selected (reduces bandwidth)

并行被关闭了
INCAR里面设置NGX=126,NGY=126,NGZ=154.
PREC=High和Accurate

貌似这样设置也不起作用,还是老问题,不知何故。。。。
