Has Windows AMD GPU BRP7

Has Windows AMD GPU BRP7 temporarily stopped?  I see 4000 in the queue, are they Cuda/Linux only?  I was getting a nice supply of Windows AMD a few hours ago.  I turned off gamma, because I need beta on to get BRP7, but beta gamma always fail on my cards and always have (nobody ever fixed that?)

If this page takes an hour to load, reduce posts per page to 20 in your settings, then the tinpot 486 Einstein uses can handle it.

The Einstein project has a policy of "only one unreliable application result per workunit". ('unreliable' including self-compiled applications and project Beta applications).

It's likely that the unsent tasks are waiting for a 'reliable' app to be declared, so that comparison tasks can be issued and validation completed.

or just check the

or just check the applications page and see that the project has pulled the Windows-AMD and Linux-Nvidia apps. so they wont be sent. 

either for updates, or they determined that those apps are good enough and don't require further testing.

I had to abort the second

I had to abort the second attempt at running an M22 task on my RX 5600 XT host (https://einsteinathome.org/host/12879640), because it was shaping up like yesterday's aborted attempt that hadn't finished after 19 hr.

After an hour, today's task was 50% complete. The GPU load, however, was at a constant 99% with constant 0% memory load, which seems unusual. My RX 570 cards have completed many M22 tasks with no problems, though still waiting on validation.

Is anyone else having issues with a Navi 10 card?

Ideas are not fixed, nor should they be; we live in model-dependent reality.

Yes to Navi.  Not trouble, and not Linux, but I have seemingly successful completion and returns awaiting validation from three systems, with

RX 5700

RX 6800

RX 6800XT

Despite heavy throttling (for reduced power consumption and room heating) the completion times mostly range from 30 to 47 seconds.

I wouldn’t be surprised if it was some kind of driver issue. Navi 10 always kind of got the short end of the stick in that regard. Also possible to be some compilation flag or argument that needs to be added.

Can't you just run less cards?

Or do what I do and open the windows.
