I think i see that everyones RAC has dropped by quite a bit..
I know a few of my machines are down 50%! So what this is all for science... Well there are a few of us who this is a bit of a competition even if only with ourselves. For a guy like me with 16yrs and ???? amount of credit so what. For anyone New or someone just donating their spare time that is a huge discouragement!! I know the whole point of the newer versions is to get more detailed results which is great but they need to allow for the meter to spin a bit faster!!!

Thanks in Advance!

I have noticed when my RAC falls suddenly, the number of valids
falls far behind pendings. So the validator seems to slow down
then speed up. Perhaps the code is being changed as part of the
prep for greenbank?

That's what happens when you aren't processing work for several weeks, which is what happened for those that make use of GPUs.

Some of my machines dropped by as much as 40% compared to the v7 applications, and that does not include the GPU work.

I really miss the optimized apps for Mac OS X from v7.

The lack of an optimised application will cause the RAC to drop, as will the effects of Credit New.
However it will probably take another 4 or so weeks (with no system outages) to see just how severe the effect will be.
And the Lunatics crew are working on optimised GPU applications, so they will help boost work output once they come online.

Another reason for the drop in RAC is that your wingmates' caches will have dropped very low while no GPU applications were available. They will have filled, to different depths at different speeds, after GPU apps became available again. The work you are returning may be matched against something issued at the same time, but buried at the end of a long queue. If your new work isn't validating immediately, and you have a lack of old work validating to fill its place, RAC will be low until you get back into equilibrium again.

This looks like a significant recent drop to me. I've been AP-only on the main machine, and my little puny single-core machine is still chewing through MBv7's.



Of course, I did go idle for...almost a week(?) before picking up more APs, but I've been crunching on them pretty solidly for over a week now and it doesn't particularly look like it is trying to climb back up to approximately where it was.

Since the AP applications haven't changed, run times should be consistent - or as consistent as they ever were. So I see three possibilities:

Fewer tasks being processed - work supply problems
Fewer tasks validating - wingmates not completing their tasks
Lower credits being awarded to each task.

The last possibility is the most interesting, but it would need a sharper tool than RAC to dissect it forensically.

Looking at the couple of validated APs I've got on my tasks page, if I remember correctly, I remember generally being around the upper 500s for the most part for most tasks. It is low 500s now for the most part, and.. more 300s than I would expect, and there's not really any correlation between amount blanked and credit given (but we knew that already.. "Random Number Generator" and so forth).

The more science your computer does the less credits, that's DA's plan. And if anyone has ANY evidence to the contrary I'd like to see it.

Mmmm..since Jan 4th, my RAC has dropped from over 15000 to just over 4200, bit of a bummer. And since it's now almost impossible to get any meaningful amount of ap's (I got 4 in the last run, that lasted 3 days) I'm gonna have to get used to it. I don't bother too much with credit, but it's something that tells me how well I'm doing. Now though, I've dropped from the top 5% to the top 25% <sigh>

still munching along though ;-)

Well it has been a bit and the lunatics optimized stuff is/has been running, This is still NOT giving the credit it once did. Not a good way IMHO to encourage new people... BTW i have 2 really nice machines down 45% Bummer!

I am way down here on RAC as well....and it's not recovering too well.

Fact is, the Lunatics apps for v8 are not what the old ones were for v7.
First of all, they are still working on further optimizations.
And second of all, v8 work is simply more complex that v7 was.
And thirdly, credit skewed is not making up the difference between the two.

As near as I can tell, it is about 30% less. This is just what I am seeing what my RAC was and what my RAC is. I don't have any hard evidence and probably won't put any effort into it.

I run totally stock, no lunatics and 2 instances on my GPU. I have changed nothing since V8 has been introduced.

The RAC score isn't too high on my list but it seems people use it as a score of some sort and it would seem they are scoring less.

my 2 cents/pence etc
