Funk
(F)ind yo(U)r (N)odes on g5(K) is a tool that help you to plan your multi-site experiments on Grid5000. It is a Python script based on Execo that give you the number of available nodes at a given moment or the time slot when the required ressources will be available. Projet source, issue and feature requests can be found here. Some basic usage can be found here. |

Configuration
No installation
A bash wrapper is installed on lyon frontend in /home/lpouilloux/bin/ and allow you to use funk without any configuration and installation. You must log into the Lyon frontend, move to the directory and type ./funk with the options you need (see below).
With installation
You need to install the git version of execo (tutorial Once it is done, you can clone the repository with:
git clone https://github.com/lpouillo/Funk.git
And run the script with ./funk.py.
Options
running
- (-m): three modes available
- now = give you the number of nodes available at the time the script is run
- free = find the slots for a combination of resources
- max = find the maximum number of nodes for the period specified.
- (-y): perform the reservation automatically
- (-v): verbose mode (a lot of debugging informations)
- (-q): quiet mode (no informations displayed)
- (-p): draw gantt diagramm and slots (require matplotlib 1.2, not available on Grid'5000 frontends)
resources
- (-r): define the elements you need by giving a comma separated list of elements (grid5000, site_uid, cluster_uid)
- element1,element2,element3 for mode now and max
- element1:n_nodes1,element2:n_nodes2,element3:n_nodes3 for mode free
- (-k): ask for a global KaVLAN
- (-o): define your oargridsub options (default = '-t deploy')
time
- (-w): walltime of the reservation (1:00:00)
- (-s): starting date for the planning computation (2013-07-12 16:12:35)
- (-e): ending date for the planning computation (2013-07-16 16:12:35)
Usage
Finding the number of available nodes from now to now + walltime
funk.py -w 1:00:00 -m now -r grid5000
Finding the first free slots for a resource combination
funk.py -w 2:00:00 -m free -r lille:10,lyon:10,sophia:10
Finding the maximum number of nodes available for the resource and with a KaVLAN
funk.py -w 10:00:00 -m max -r lyon,sophia,edel -k
