[交流] 【求助成功】如何处理算不动的情况

我计算BaFe2As2体系的掺杂的结构驰豫，80个原子，5×5×5的kmesh，结果算不动了。由于以前算过CaFe2As2的80个原子的掺杂，结构跟这个是一样的、参数也一样，就直接拿过来用了，本来以为没有问题的但是发现算不动了（集群仍然会失去响应，并且把进程杀死）。我top了一下

我以为是内存不够了（占用了将近90%），根据说明书的《6.68   Not enough memory, what to do》修改了INCAR

System = BaFe2As2 afm1-DopSe:3.125%
PREC = Accurate
ISPIN = 2
MAGMOM = 16*0 16*3 16*-3 32*0
ISMEAR = 1
SIGMA = 0.20
ISTART = 0
EDIFF = 1E-5
EDIFFG = -1E-3
ICHARG = 2
ENCUT = 310
NSW = 60
IBRION = 2
ISIF ＝ 3 #Full relaxtion
POTIM ＝ 0.2
LORBIT = 11

LREAL = Auto
LPLANE ＝ .TRUE.
LSCALU ＝ .FALSE.
LCHARG = .FALSE. #连同的LWAVE和ISYM都是根据说明书上的设置的
LWAVE = .FALSE.
ISYM = 0
NPAR ＝ 1
NSIM ＝ 4

结果发现还是不行，却好像不是内存不够，但是集群仍然会失去响应，并且把进程杀死

请问大家是如何应对算不动的情况的呢？kpoints

这个在要求精度不变的情况下，只能牺牲速度，你用的是几个核心？你只用一个核心提交任务试试，应该没问题。

我使用两个进程提交任务，提示虚拟内存不足；使用了一个进程进行计算，发现计算会很快退出并提示段错误，不管是并行（使用IFC）还是串行（使用gfortran）

对于80个原子这么多的体系，我的建议是K点取为1 1 1就可以了

对于80个原子这么多的体系，我的建议是K点取为1 1 1就可以了

对于Monhkorst-Pack来说，它的最小k点为4，我使用3 3 3的kmesh都会提示出错。要想使用1 1 1就不能使用Monhkorst-Pack，要使用Gamma了。
