Topic 225940

We are aware that currently quite some results computed with various, particularly ARM-based devices "lose" validation when compared to that of the dominating Intel GPUs. We are still working on solving this in the application code, but due to various issues this will take some more time.

To improve the situation that is understandably frustrating for some of you, we are reviving the "BRP4G" application and will let the Intel GPUs run these, so the results will be validated only among those. The other devices will keep processing BRP4 work and validate only in that group.

As the results from the

As the results from the current BETA applications are collected and it is determined that the application is in fact running at a low enough error rate to make the application version is safe to be run by everyone can the BETA status be removed so that main line users who have not agreed to run "TEST Applications" can receive the new versions of the Applications ?

 

Thanks

I'd be against doing that

I'd be against doing that just yet. I've been running these tasks on some sample machines since the BRP4G run was restarted. I'd say that my results on HD 4600 GPUs are OK, but anything later than that is still problematic.

Take these stats from an HD 530 (still over 5 years old - nowhere near the cutting edge):

Check those figures very carefully. The separate categories add up to 238, leaving 146 unaccounted for. They are all 'validation inconclusive' against the stock application. Coupled with the figure of 69 invalid, I'd say that's unacceptable from a quality control point of view. The machine is a Dell Optiplex 5040 desktop, with no overclocking or other stressors.

Bernd intimated to me privately - just before his holidays - that "...  we finally have someone actively working on it now, so we're getting back to it. I'll take a look at this issue." I'm ready and willing to take part in that investigation whenever called upon: I have some some experience of tackling similar issues at SETI@Home.

I agree with Richard I too would like the apps to be pretty solid before the drop of BETA status. I was thinking more of the two BETA's that have release dates in 2019.
