什么原因使得“on signal 9 (Killed)”

[Joann]

大家好，计算后发现求解器的log在算第一个时间的时候就出现了这样的情况：

Primary job  terminated normally, but 1 process returned
a non-zero exit code. Per user-direction, the job has been aborted.
--------------------------------------------------------------------------
[joann:06935] Read -1, expected 5328, errno = 3
[joann:06936] Read -1, expected 5400, errno = 3
[joann:06926] Read -1, expected 5400, errno = 3
[joann:06931] Read -1, expected 10368, errno = 3
[joann:06932] Read -1, expected 5616, errno = 3
[joann:06933] Read -1, expected 6984, errno = 3
--------------------------------------------------------------------------
mpirun noticed that process rank 0 with PID 0 on node joann exited on signal 9 (Killed).

对于这个问题有点迷茫，特来请教各位一下如何解决这个问题？

可能是计算机内存不够用或者内存越界之类的

@bestucan 多谢，好的我看看您分享的几个帖子，经常在第一个时间步遇到on signal 9（killed）和on signal 8（floating point exception），一直以为是设置的边界条件不对的问题。

@joann
我经常遇到，是内存不足。
网格减少
虚拟机的话，增加内存
跟CPU多少核关系不大

@五好青年 请教一下，我最近也遇到“on signal 9 （killed）”这个问题，目前使用的服务器内存128G的，网格也才400多万，我看运行的时候内存占用不过10%左右，但是还是会出现上述情况，有点迷惑。

您好，看到您发的帖子，我想请教一下，我最近也遇到“on signal 9 （killed）”这个问题，目前使用的服务器内存128G的，网格也才400多万，我看运行的时候内存占用不过10%左右，但是还是会出现上述情况，有点迷惑，您发的链接我也都看过，尝试了很多方法仍然没解决。看您提到了内存越界，想咨询一下如果是这个原因，那么应该怎么解决呢，多谢。

mpirun noticed that process rank 4 with PID 0 on node ps exited on signal 9 (Killed).

你这个错误的信息log没有输出出来

mpirun noticed that process rank 4 with PID 0 on node ps exited on signal 9 (Killed).

这个不是错误信息
