script: rewrite the launch.py script in a more complete form : scripts/bench.py

[svalat]

Waiting merge

Note: Maybe wait it has been validated on another cluster before merging.

Scripts

Write a single script to :

• clone and build idefix
• generate the jobs
• submit them
• extract the performance

All is currently in the new ./scripts/bench.py which was started by reshaping ./scripts/launch.py and extending it with what ./scripts/run-bench was doing.

This patch currently let the original scripts in place.

Schedulers

The ./scripts/bench.py now supports :

• slurm
• oar
• sh (local)

The choice depends on the extension name for the script.* file in the cluster definition (begin script.slurm, script.oar or script.sh.

Clusters

It also adds two clusters :

• kraken (cpu/mpi & gpu/h1OO)
• localhost (cpu / openmp) => to help validating the script.

.gitignore

Mask the default idefix and runs directories.
