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:

Running the tool
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 and run it:
ssh lyon /home/lpouilloux/bin/funk -h
With installation
You need to install the git version of execo. 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
- date = 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)
- (-c): choose a timeslot that is out of Grid'5000 charter time
Usage
Number of available nodes on stremi cluster from date to date + walltime
funk -m date -s "2013-11-18 10:41:25" -r stremi
First free slots for a resource combination with deploy job type and a KaVLAN
funk -m free -w 2:00:00 -r grid5000:100,taurus:4 -o "-t deploy" -k
Maximum number of nodes available for the resources, avoiding charter periods
funk -m max -w 10:00:00 -r nancy,paradent,edel -c
