Configuration
No installation
A bash wrapper is installed on lyon frontend in /home/lpouilloux/bin/funk and allow you to use funk without any configuration. Just type ./funk with the options you need (see below)

mode
Three modes (-m):
- 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.
resources
Define with (-r) 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

Usage
Examples
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
