Hi Alexis,
if you just want to run them again, using the same submit-side setup (configuration, executable, job parameters, …), it is generally enough to increase the retry count for jobs. This is will resubmit any failed jobs, leaving the successful jobs untouched.
From the command line, ``-m, --max-retry`` does the job (e.g. ``./go.py -m10 <config>`` to retry up to ten times). In the configuration, ``[jobs] max retry`` does the same.
Note that if you have based your config on someone else’s config, it can happen that you have implicitly disabled retries via ``[global] cmdargs = -m 0`` which overwrites ``[jobs] max retry``.
Cheers,
Max
