命令执行结束,释放资源。 分配模式通过 salloc 命令运行,举例如下(使用 2 个节点,4 个进程,预计运行时间 100 秒): $ salloc-N2-n4-p example-partition-t100/bin/bash 资源分配请求成功后会进入 bash shell 终端,在其中可以使用 srun 交互式地执行作业任务。在终端输入 exit 命令或 Ctrl+D 退出分配模式。 天...
Interactive step inside of container: salloc --container $ABS_PATH_TO_BUNDLE bash -c "cat /etc/*rel*" Interactive job step 0 inside of container: salloc srun --container $ABS_PATH_TO_BUNDLE bash -c "cat /etc/*rel*" Job with step 0 inside of container: ...
When LaunchParameters=use_interactive_step is enabled, launching salloc will automatically start an srun process with InteractiveStepOptions to launch a terminal on a node in the job allocation. The default value is "--interactive --preserve-env --pty $SHELL". The "--interactive" option is int...
Starting in 20.11, the recommended way to get an interactive shell prompt is to configure use_interactive_step in slurm.conf: LaunchParameters=use_interactive_step This configures salloc to automatically launch an interactive shell via srun on a node in the allocation whenever salloc is called witho...
if you see that salloc'ed interactive job is scheduled to run much later than you need, try to cancel the job and ask for shorter period - often there might be a closer window for a shorter time allocation. Logging If we need to separate logs to different log files per node add %N ...
With preemptible_bursting on, when a node is found preempted, or stopped, the slurm-gcp sync script will mark the node as "down" and will attempt to restart the node. If there were any batch jobs on the preempted node, they will be requeued -- interactive (e.g. srun, salloc) jobs...

Interactive shell. 使用srun --pty bash可以进入interactive shell. 这也是比较浪费的使用方式, 不过这个模式非常接近我们平时ssh到服务器的方式, 可能能够帮助我们学习debug. SoC的cluster不支持我们直接ssh进入compute node. 1. 用salloc和srun salloc -G titanv ...
The best method is to use salloc with use_interactive_step set in the LaunchParameters option in slurm.conf. See getting shell prompts in interactive mode. How can I get shell prompts in interactive mode? Starting in 20.11, the recommended way to get an interactive shell prompt is to configu...
An interactive salloc may fail to launch since it will try to spawn the default shell, which according to the slurmctld is /sbin/nologin. When using proctrack/pgid, nss_slurm will rely on the pgid of the process to determine if it can respond to that request. The login shell spawned...
