我正在尝试设置泥浆在装有 Raspbian 9.4 的 Raspberry Pi 集群中。
我可以启动slurmctld，但是当我尝试启动时slurmd我得到以下输出：
pi@node1:~ $ slurmd -Dvvvc
slurmd: debug: Log file re-opened
slurmd: error: Domain socket directory /SHARED/slurm/var/slurmd.node1:

slurmd: error: Couldn't load specified plugin name for proctrack/cgroup:

我的配置文件是：

SlurmdUser=pi

CryptoType=crypto/openssl

我错过了什么？
答案1
问题在于 cgroup 未正确配置。您可以配置它或更改 proc 跟踪类型。
在 slurm.conf 文件中应该有一个名为 ProctrackType 的变量。如果您想将其更改为无需 cgroup 即可运行的解决方案，可以将其设置为：
ProctrackType=proctrack/linuxproc
如果变量不存在，您也可以简单地添加此行。
