无法在PC上安装Slurm

我正在尝试在 Ubuntu PC 上安装 slurm。因此，我按照上面给出的说明进行操作这里

我做了以下事情 -

  1. sudo apt update -y
  2. sudo apt install slurmd slurmctld -y
  3. mkdir sudo /etc/slurm-llnl 仅供参考...我自己想出了步骤 3
  4. sudo chmod 777 /etc/slurm-llnl
sudo cat << EOF > /etc/slurm-llnl/slurm.conf

  1. sudo systemctl start slurmctld
  2. sudo systemctl start slurmd

现在，当我这样做时——

  1. sudo scontrol update nodename=localhost state=idle

我收到错误 -

scontrol: error: resolve_ctls_from_dns_srv: res_nsearch error: Unknown host
scontrol: error: fetch_config: DNS SRV lookup failed
scontrol: error: _establish_config_source: failed to fetch config
scontrol: fatal: Could not establish a configuration source

我按照保罗的指示进行了操作。现在，我得到以下输出 -

答案1

你也开始munge服务了吗？

确保也按systemctl如下方式启动它。

sudo systemctl start munge
sudo systemctl status munge

我建议你关注本指南我写了一篇关于如何在 Ubuntu 22.04 的单节点环境中安装 Slurm 的文章。

干杯。

答案2

通过查看您提供的 systemctl 配置，我可以告诉您以下内容：

1-至于含糊不清，您在 slurm.conf 中定义的硬件配置不正确。此配置将在其上运行的节点的硬件规格是什么？

 (Mar 05 05:57:17 thoma-Lenovo-Legion-5-15IMH05H slurmd[6514]: slurmd: error: Node configuration differs from hardware: CPUs=12:12(hw) Boards=1:1(hw) SocketsPerBoard=12:1(hw) CoresPerSocket=1:6(hw) ThreadsPerCore>)

根据此输出，您的值每板插座数和每个插槽的核心数， 应该1和6分别。

2- 关于slurmctld，初始节点状态应该是未知， 像这样。

 NodeName=localhost CPUs=12 RealMemory=30517 State=UNKNOWN PartitionName=localhost Nodes=ALL Default=YES MaxTime=INFINITE State=UP

注意：我看到你把“8000“ 身为你的真实记忆价值。尝试使用值“8192" 相反，Slurm 使用 MiB 值:)

然后尝试改变这些重新开始两个都含糊不清和slurmctld让我知道这是否有帮助。

干杯!
