For me, the assigned credit seems to have more than halved with the new version :(

A very small change was made to allow Red Hat Enterprise Linux 6 hosts to run ATLAS WU without Singularity. I didn't realise that the credit algorithm was affected by new app versions... but I suppose as usual it evens out in the long term.

Thanks David for looking into this, even though we all pretend we don't really care about the credits :)

Out of interest, how long are you expecting to support Atlas-native on SL6 for? Until SL6 EoL (autumn 2020 IIRC) or will it be retired sooner?

Credits earned by my hosts running ATLAS native increased with the transition from 2.55 to 2.57 rather than decreased.

Mine definitely decreased initially (from ~650 to ~250 per task) but then increased again (~750) around the time of David's post...

(Unfortunately the history's "scrolled off" the host page now.)
