[求助] 求助VASP能带计算的中断原因

我用的两个节点并行计算。发现算能带结构时，到最后一步总是出错，是否是因为最后写入波函数需要大内存，导致退出呢？

具体log如下所示：

CODE:

 running on    8 nodes

 distr:  one band on    1 nodes,    8 groups

 vasp.5.2.11 18Jan11 complex 

 POSCAR found type information on POSCAR  N  O  Ti  Ag

 POSCAR found :  4 types and      88 ions

 LDA part: xc-table for Pade appr. of Perdew

 found WAVECAR, reading the header

  number of k-points has changed, file:     8 present:    77

  trying to continue reading WAVECAR, but it might fail

 WARNING: stress and forces are not correct

 POSCAR, INCAR and KPOINTS ok, starting setup

 WARNING: small aliasing (wrap around) errors must be expected

 FFT: planning ...(           1 )
