在Ubuntu 16.04桌面上安装/模拟SLURM：slurmd无法启动

编辑

我真正想要的是一种模仿SLURM的方法,一种可以安装的交互式和合理用户友好的方式.

原帖

我想用SLURM测试一些最小的例子,我试图用Ubuntu 16.04在本地机器上安装它.我跟随the most recent slurm install guide I could find,然后我开始使用sudo /etc/init.d/slurmd start开始slurmd.

[....] Starting slurmd (via systemctl): slurmd.serviceJob for slurmd.service failed because the control process exited with error code. See "systemctl status slurmd.service" and "journalctl -xe" for details.
 failed!

我不知道如何解释systemctl日志：

● slurmd.service - Slurm node daemon
   Loaded: loaded (/lib/systemd/system/slurmd.service; enabled; vendor preset: enabled)
   Active: failed (Result: exit-code) since Thu 2017-10-26 22:49:27 EDT; 12s ago
  Process: 5951 ExecStart=/usr/sbin/slurmd $SLURMD_OPTIONS (code=exited,status=1/FAILURE)

Oct 26 22:49:27 Haggunenon systemd[1]: slurmd.service: Failed with result 'exit-code'.

lsb_release -a给出以下内容. (是的,我知道,严格来说,KDE Neon并不完全是Ubuntu.)

o LSB modules are available.

与导游说的不同,我使用了自己的用户名wlandau,我确保将/ var / lib / slurm-llnl和/ var / run / slurm-llnl chown给我.这是我的/etc/slurm-llnl/slurm.conf.

在@damienfrancois的帮助下重写我的slurm.conf之后,slurmd现在开始了.但不幸的是,当我调用它时,sinfo挂起,我得到了和以前一样的错误信息.

$sudo /etc/init.d/slurmctld stop
[ ok ] Stopping slurmctld (via systemctl): slurmctld.service.
$sudo /etc/init.d/slurmctld start
[ ok ] Starting slurmctld (via systemctl): slurmctld.service.
$sinfo
slurm_load_partitions: Unable to contact slurm controller (connect failure)
$slurmd -Dvvv
slurmd: fatal: Frontend not configured correctly in slurm.conf.  See man slurm.conf look for frontendname.

然后我尝试重新启动守护进程,并且slurmd无法重新开始.

$sudo /etc/init.d/slurmctld start
[....] Starting slurmd (via systemctl): slurmd.serviceJob for slurmd.service failed because the control process exited with error code. See "systemctl status slurmd.service" and "journalctl -xe" for details.
 failed!

ControlMachine前面的值必须与slurmctld启动的机器上的主机名-s的输出相匹配. NodeName也是如此;它必须匹配slurmd启动的机器上的主机名-s的输出.因为你只有一台机器,它似乎被称为Haggunenon,slurm.conf中的相关行应该是：

ControlMachine=Haggunenon
[...]
NodeName=Haggunenon CPUs=1 State=UNKNOWN

如果要启动多个slurmd守护程序来模拟更大的集群,则需要使用-N选项启动slurmd(但这需要使用–enable-multiple-slurmd configure选项构建Slurm)

UPDATE.这是一个演练.我用Vagrant和VirtualBox设置了一个虚拟机(vagrant init ubuntu / xenial64; vagrant up)然后在vagrant ssh之后运行以下命令：

如果按照此处的确切步骤没有帮助,请尝试运行

sudo slurmctld -Dvvv

和

sudo slurmd -Dvvv

消息应该足够明确.
