python - 使用 Ipython 并行在 PBS 集群上注册超时

Question

我正在尝试使用 PBS 调度在 Linux 集群上设置 ipython 并行。

我按照 http://www.andreazonca.com/2013/04/ipython-parallell-setup-on-carver-at.html 上的说明进行操作(官方说明更难遵循)。我在头节点上运行命令，头节点使用 PBS(即标准集群配置)将作业发送到从属节点。

我的问题是超时。我尝试将等待时间从 2 秒增加到 20 秒，但没有成功。任何帮助，将不胜感激。完整输出如下。

实际上，最终我希望能够从 ssh 连接的笔记本电脑而不是集群头节点运行 ipython 命令，但我认为这是合理的第一步。

更新以下 Andrea Zonca 的建议

添加

c.HubFactory.ip = '*'

似乎有帮助，尽管由于某种未知原因没有立即发挥作用。

但它仍然不起作用:

我运行

./.ipython/profile_default/ipc 2 1

2013-09-09 12:19:51,884.884 [IPClusterStart] Using existing profile dir: u'/home/username/.ipython/profile_default'
2013-09-09 12:19:51.889 [IPClusterStart] Starting ipcluster with [daemon=False]
2013-09-09 12:19:51.890 [IPClusterStart] Creating pid file: /home/username/.ipython/profile_default/pid/ipcluster.pid
2013-09-09 12:19:51.890 [IPClusterStart] Starting Controller with LocalControllerLauncher
2013-09-09 12:19:52.890 [IPClusterStart] Starting 2 Engines with PBS
2013-09-09 12:19:52.904 [IPClusterStart] Job submitted with job id: '4783'
2013-09-09 12:20:22.904 [IPClusterStart] Engines appear to have started successfully

然后在头节点上运行:

>IPython.parallel import Client
>rc = Client()
>lview = rc.load_balanced_view()

但是输出

>rc.ids

是

[]

所以我尝试运行

ipcontroller --port=8888

然后运行nmap

$nmap -sT -O localhost
...
8888/tcp  open  sun-answerbook
...

这表明端口已打开，并且 telnet 确实给了我来自从属节点的响应。

但是当我运行上面的原始命令时 即，

./.ipython/profile_default/ipc 2 1

nmap 显示没有端口处于打开状态。所以问题似乎是在 qsub 文件中运行的 ipengine 没有像从命令行运行 ipcontroller 那样打开端口。

这是 qsub 文件:

$cat /home/username/.ipython/profile_default/pbs.engine.template.ppn2 
#!/bin/sh
#PBS -q longqueue
#PBS -l nodes={n/2}:ppn=2
cd $PBS_O_WORKDIR
which ipengine
mpirun -np {n} ipengine --timeout=20

这是我的/home/username/.ipython/profile_default/ipcluster_config.py:

c = get_config()

c.IPClusterStart.controller_launcher_class = 'LocalControllerLauncher'
c.IPClusterStart.engine_launcher_class = 'PBS'
c.PBSLauncher.batch_template_file = u'/home/username/.ipython/profile_default/pbs.engine.template' 

Answer 1

您需要允许从其他主机连接到 Controller ，在~/.config/ipython/profile_default/ipcontroller_config.py中设置:

c.HubFactory.ip = '*'

顺便说一句，我还更新了博客文章。
