Installation¶

Requirements
Installation from PyPI (pip)
Clone from git
- Switch to a different branch
- Pull remote changes

Note: If you are using grid-control with the NAF, you can use the central installation.

Requirements¶

Requirements on the submission host:

CPython 2.3 – 3.5 / pypy 2.4 – 5.3 with python standard libraries
(optional) requests – for faster interactions with webservies
(optional) cherrypy – for web based user interface
(highly recommended) a supported submission backend (ARC, Condor, CreamCE, glite/-wms, PBS, LSF, SLURM, JMS, GridEngine)

Requirements on the worker nodes:

bash, GNU coreutils, awk, sed
(optional) gfal / other supported transfer tools – for storage access
(optional) cvmfs – to allow running the LHC experiment software

Installation from PyPI (`pip`)¶

Note: Since the PyPI release is rather outdated at the moment, we recommend cloning from git.

$ pip install --user grid-control

This installs the default go.py executable. In addition the executalbe gridcontrol is provided, because of the more descriptive name.

Clone from git¶

# whereever you check out your projects
$ cd <your project path>
$ git clone https://github.com/grid-control/grid-control.git
Cloning into 'grid-control'...
remote: Enumerating objects: 43, done.
remote: Counting objects: 100% (43/43), done.
remote: Compressing objects: 100% (27/27), done.
remote: Total 18566 (delta 26), reused 31 (delta 16), pack-reused 18523
Receiving objects: 100% (18566/18566), 6.39 MiB | 4.70 MiB/s, done.
Resolving deltas: 100% (14715/14715), done.

Now one option is to place a link to the executable in a location contained in your PATH environment variable. Assuming ~/bin is such a location (check with echo $PATH):

$ cd ~/bin
$ ln -s <your project path>/grid-control/go.py grid-control

Now you can use the grid-control executable, instead of the standard go.py, which is not very descriptive.

Switch to a different branch¶

Different branches can be used. E.g. testing for more up-to-date changes:

$ cd <your project path>/grid-control
$ git checkout testing
Branch 'testing' set up to track remote branch 'testing' from 'origin'.
Switched to a new branch 'testing'

Pull remote changes¶

Update your version with upstream changes from the current branch (make sure you are on the local branch that you want to update):

$ cd <your project path>/grid-control
$ git pull
