ATLMCPROD-10749

Checklist for approval

This checklist should be normally filled by MC contacts (but it can also be done by the person opening the merge request).
If something is unclear get in touch with the repository maintainers.

• [ X] I have followed the guidelines in McSampleRequestProcedure
• [ X] I have provided the ATLMCPROD JIRA ticket where the request has been discussed
• [ X] The request has been approved by the PA/CP group:
  Rquest discussed in GIT meeting 23 June 2023
• The pipeline has run and the status is green (still check the CI job output - if you see any errors report to the repository maintainers)
• If the pipeline is orange: check the CI job output to sort out the issues. If the issue is unclear contact the repository maintainers
• CI jobs have not been skipped (if jobs have been skipped, the requesters should provide a reason for skipping and confirmation from the PMG conveners is necessary before merging) Note: DSID 950739 uses 100 input files (the max allowed by the commit script) but the CPU time is very short. This results in an error being reported in the commit script. Spiros suggested I use the -u flag to ignore the error. As a result, CI is not run.
• Check that no log.generate.short files are included in the commit to be merged to master. If such files are present, it indicates that something went wrong in the pipeline. Check the job logs and contact the package maintainers if needed. See above
• Check that the title of the MR is descriptive enough (if not ask the requester to modify it)
• [ X] Check that the DSID range assigned is correct (500000-999999) and corresponds to right generator block
