I just noticed that the new Atlas Native 2.85 version is getting less credit for the same run time compared to v2.84.
Honestly these Native units require jumping through a number of hoops to get running reliably, you'd think they'd attract a bonus for those willing to put in the extra setup work.

Every version change comes with a cut in credits, but after a couple of workunits credit returns to "normal" values. Proof: https://lhcathome.cern.ch/lhcathome/results.php?hostid=10672881
Why? No one knows. The Boinc credit system is a mystery to everyone.

Credits always go up or down after a version change but this will automatically return to your long term average after a while.


A recent comment regarding the credit system can be found here:

The project team at CERN used that for years and will most likely not change it within the next few years.


Nobody is forced to run native apps.
They have been developed to satisfy large cluster's needs in computing centers and are offered here as an option.
Feel free to use vbox apps instead.

Having gone to the trouble of getting the native apps to work, being told to go back to the vbox app is rather insulting.

Hmmm...i wonder where this is an insult!? It's an explaination why native apps are a bit more complicated to set up.
Believe me: user 'computezrmle' is one of the good guys here and has outstanding technical understanding regarding LHC@home and i'm absolutely sure that he had no intention to insult anyone here! He's just here to help.

BTW: This post is also not intended to insult anyone!
