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 nodes available at a date and for walltime find the slots for a combination of resources and a walltime find the slot with the maximum number of nodes for a period and a walltime. Some basic usage can be found here. Projet source, issue and feature requests can be found here.

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:

 /home/lpouilloux/bin/funk.sh -h

This is a temporary solution that will be replaced soon by a installation on every Grid'5000 frontend

With installation

You need to install the execo 2.2. Once it is done, you can clone the repository with:

 git clone https://github.com/lpouillo/Funk.git

And run the script with the options you need.

 -q, --quiet           Run without printing anything
 -v, --verbose         Run in verbose mode
 -p PROG, --prog PROG  The program to be run when the reservation start
 --plots               Draw a Gantt plot and the slots

Reservation

Customize your Grid'5000 reservation.

 -r RESOURCES, --resources RESOURCES
                       Comma separated list of Grid'5000 elements (grid5000, site or cluster)
                       -r element1,element2 for date and max modes
                       -r element1:n_nodes1,element2:n_nodes2 for free mode
 -b BLACKLIST, --blacklist BLACKLIST
                       Remove clusters from planning computation
 -R RATIO, --ratio RATIO
                       Apply a given ratio to the resources found, works only for mode date and max
 -o OARGRIDSUB_OPTS, --oargridsub_opts OARGRIDSUB_OPTS
                       Extra options to pass to the oargridsub command line
 -k, --kavlan          Ask for a KaVLAN
 -j JOB_NAME, --job_name JOB_NAME
                       The job name passed to the OAR subjobs

Time

Define options related to date and time.

 -w WALLTIME, --walltime WALLTIME
                       Reservation walltime in OAR format
 -s STARTDATE, --startdate STARTDATE
                       Starting date in OAR format
 -e ENDDATE, --enddate ENDDATE
                       End date in OAR format
 -c, --charter         Avoid charter periods

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
