WIP: (testing, CI) Run up to 4 gauss jobs at once in run-gauss CI test
The run-gauss test can take a long time to complete as Gauss is run for each decfile sequentially. I opened this MR to slightly modify the test to allow up to 4 Gauss processes (can be tuned to suit) to be run in parallel at once. There may be reasons I'm not aware of that mean this is not a good idea (apologies if this is the case.)
Examples:
- when one or more decfiles fail: https://gitlab.cern.ch/lhcb-datapkg/Gen/DecFiles/-/jobs/12752673
- when all decfiles pass: https://gitlab.cern.ch/lhcb-datapkg/Gen/DecFiles/-/jobs/12753189
For comparison with old test:
- when one or more decfiles fail: https://gitlab.cern.ch/lhcb-datapkg/Gen/DecFiles/-/jobs/12750344
- when all decfiles pass: https://gitlab.cern.ch/lhcb-datapkg/Gen/DecFiles/-/jobs/12752226
Todo:
- test scenario where one or more of the decfiles fail
- test scenario where all the decfiles pass
- remove test decfiles included in this MR before marking ready
- rebase + squash
