I've been crunching Rosetta@Home successfully for months.
I recently added World Community Grid (WCG) to my BOINC manager, showing 50% priority.
Rosetta@Home also showed 50% priority.
Everything was good... WCG had 50% of my machine and R@H had 50% of my machine regarding task load.

But, I checked my tasks on the R@h site just now and noticed that all my R@H stats were zero - nothing completed, nothing being processed...
Then I went to my computer and I see that it's ALL WCG tasks running now. No R@H.
The log shows for R@H: "Not requesting tasks: don't need (CPU: not highest priority project; NVIDIA GPU) when I try a manual update.

I've successfully run a mix of projects before without any special intervention on my part.
What has gone wrong?

Thanks.

Try limiting the number of WCG tasks using device profiles. https://www.worldcommunitygrid.org/ms/device/viewDevices.do

It'll prevent WCG from overfilling your queue in computation preferences.

Resource share isn't about the number of running Tasks and any given time, it's about the amount of work done for each project, and that is determined by REC (Recent Estimated Credit- which is like RAC, only different).
For whatever reason, Rosetta has gotten ahead of WCG as far as your Resource share settings are concerned, and it's just balancing the books. Once things have levelled out again, it will start doing Rosetta again.


Edit- look at your RAC for each project
       Rosetta@home  8,099
World Community Grid 1,630

REC is different from RAC, but it's pretty obvious that significant processing time is owed to WCG to get things to a 50:50 Resource share.
And reducing the size of your cache (0.4 days an 0.02 extra days is plenty) will help settle things down sooner rather than later.

If you haven't run WCG for a while, Boinc will see a "Deficit" there and will try to do proportionately more work for it to bring it up to parity with your other Project(s) eventually matching your resource share. I'm sure there's a manual edit of a Boinc file to bypass the delay while Boinc sorts itself out but I can't remember which, or what value to set.

Cross-posted with Grant but I concur.

Ah yes! This makes sense.

Thank you all very much!

Nothing.
You have a 50/50 resource share, but recent tasks completed are 100% Rosetta, 0% WCG
WCG will run exclusively until it matches what you asked for - 50/50
It's that simple
