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'

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'
最佳答案
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 = '*'
