That sounds kind of counter-intuitive. So if I allow test application I get nothing but? In other projects it certainly doesn't work that way.
Although now that you mentioned it I vaguely recall discussion about this.

It kind of seems that when requesting work it fills the work buffer from the first experiment with work available. As I run a multiday buffer it makes sense that I get lots of WUs from a single experiment. This however doesn't explain why it's always the same experiment. Personally I would prefer a spread of WUs. This is however not really an issue since according to the status page work is getting done on all experiments.
What with all CERN BOINC projects being assimilated under a single project I'm kind of wondering if everything is working as intended.

Basically I'm asking what actually happens when I tick the 'all applications' box in my preferences.

I've been wondering what determines which WUs my machines receive. All of my computers seem to run pure LHCb with occasional dashes of sixtrack. I can't recall the last time I've seen a CMS unit let alone any others. My settings should allow all. I've even set up my app_config in a way that limits simultaneous work from a single experiment but not several.
Looking at the status page there should be work available under multiple experiments...

Yeah well, it is "better" now. Not all of them fail. Current ratio for me is 18 valid vs 33 error. It seems kind of odd that my machines are running nothing but LHCb if there is no actual work to be done.
33 x 15 minutes of runtime per failed unit equals over 8 hours of wasted computation. Seriously considering disabling LHCb again.

After moving my machines over to LHC@home I've left my settings as the defaults. So far I don't think I've crunched a single LHCb unit successfully. Theory, CMS, sixtrack no problems. LHCb fail after fail. Good old EXIT_INIT_FAILURE.
It kind of seems pointless to keep this up. So should I just give up and disable LHCb again?
