Registration timeout on PBS cluster with Ipython parallel

1
votes

I'm trying to set up ipython parallel on a linux cluster using PBS scheduling.

I was following instructions at http://www.andreazonca.com/2013/04/ipython-parallell-setup-on-carver-at.html (the official instructions are much harder to follow). I'm running the command on the head node, which sends the jobs to the slave nodes with PBS (ie, a standard cluster configuration).

My problem is that I get a timeout. I tried increasing the waiting time from 2s up to 20s but without success. Any help would be appreciated. Full output is below.

Actually, in the end I want to be able to run the ipython commands from my ssh-connected laptop rather than from the cluster-head-node, but I thought this was a reasonable first step.

Update following advice from Andrea Zonca

Adding

c.HubFactory.ip = '*'

appears to help, although not immediately for some unknown reason.

But it still doesn't work:

I run with

./.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 12:20:22.904 [IPClusterStart] Engines appear to have started successfully

and then run on the head node:

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

but the output from

>rc.ids

is

[]

So I tried running

ipcontroller --port=8888

and then run nmap

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

which shows the port is open, and sure-enough telnet gives me a response from the slave node.

But when I run the original command above ie,

./.ipython/profile_default/ipc 2 1

nmap shows no port as being open. So the problem appears to be that ipengine run in the qsub file is not opening the port like ipcontroller run from the command line is.

Here is the qsub file:

$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

and here is my /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'

can you post also the terminal log after you run the ipc script? the PBS script has nothing to do with the controller, the controller is just run locally on the login node. The pbs script just launches the engines. - Andrea Zonca
try change: c.IPClusterStart.controller_launcher_class = 'LocalControllerLauncher' to c.IPClusterStart.controller_launcher_class = 'Local' - Andrea Zonca

You need to allow connections to the controller from other hosts, setting in ~/.config/ipython/profile_default/ipcontroller_config.py:

c.HubFactory.ip = '*'

Btw, I also updated the blog post.
