Ubuntu 16.04デスクトップへのSLURMのインストール/エミュレート：slurmdの起動に失敗する

編集

私が本当に探しているのは、インストールできるインタラクティブで適度にユーザーフレンドリーなSLURMをエミュレートする方法です。

元の投稿

SLURMを使用していくつかの最小限の例をテストドライブしたいのですが、Ubuntu16.04を使用してすべてをローカルマシンにインストールしようとしています。私は 私が見つけた最新のslurmインストールガイド をフォローしていて、「slurmdをSudo /etc/init.d/slurmd startで開始」まで到達しました。

[....] 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!

systemctlログの解釈方法がわかりません：

● 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

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

lsb_release -aは次のようになります。 （はい、私は知っています、厳密に言えば、KDE ​​Neonは正確にUbuntuではありません。）

o LSB modules are available.

ガイドが言ったのとは異なり、私は自分のユーザー名wlandauを使用し、chown/var/lib/slurm-llnlと/var/run/slurm-llnlを確認しました。これが私の/etc/slurm-llnl/slurm.confです。

ファローアップ

@damienfrancoisの助けを借りて私のslurm.confを書き直した後、slurmdが今始まります。しかし、残念ながら、呼び出すとsinfoがハングし、以前と同じエラーメッセージが表示されます。

$ 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.

次に、デーモンを再起動しようとしましたが、slurmdを最初からやり直すことができませんでした。

$ 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の前の値は、slurmctldが起動するマシンでの_hostname -s_の出力と一致する必要があります。同じことがNodeNameにも当てはまります。 slurmdが起動するマシンの_hostname -s_の出力と一致する必要があります。マシンは1つしかなく、Haggunenonと呼ばれているように見えるため、_slurm.conf_の関連する行は次のようになります。

_ControlMachine=Haggunenon
[...]
NodeName=Haggunenon CPUs=1 State=UNKNOWN
_

より大きなクラスターをエミュレートするために複数のslurmdデーモンを起動する場合は、_-N_オプションを指定してslurmdを起動する必要があります（ただし、Slurmは_--enable-multiple-slurmd_設定オプション）

更新。これがウォークスルーです。 VagrantとVirtualBox（_vagrant init ubuntu/xenial64 ; vagrant up_）を使用してVM）をセットアップし、_vagrant ssh_の後に、次のコマンドを実行しました。

ここで正確な手順を実行しても問題が解決しない場合は、実行してみてください

Sudo slurmctld -Dvvv

そして

Sudo slurmd -Dvvv
