I'm not sure what you are saying?  Can you elaborate?

I just saw it. half mhash for 17 blocks now... why?

cgminer 2.4.1 cant upgrade

What he probably means is that cgminers mhash is approx half, in my case from 320 to 160 MH.

For me seen also with cgminer 2.4.1 but directly against stratum proxy (tested both) 0.5.0 and 0.8.3, (against btcguild ). Only clue for me yet is that its a 6950, 3 other 5850 same setup, no problem. Maybe you also got a 6950 ?

Just to verify:  Do you mean you had the same problem on BTC Guild (with Stratum), or that it worked fine on BTC Guild?

If you had the problem on BTC Guild, was the hash rate on the BTC Guild website displaying accurately (and cgminer was just wrong)?  I'm wondering if old cgminer versions calculated hashrate assuming submissions would always be difficulty=1.  New versions definitely don't have any problem.

until 2 days ago it was ok, 10ghash and normal submitting.

something changed yesterday/todays night ? Eclipse is showing only 5hash and my income is half too.

Cgminer hash rate isn't a calculation in anything except Icarus Abort (mandatory there for all mining software)
Everywhere else it is simply a counter.

However, the U: is still share based, not difficulty based.
WU: is 1 difficulty based, but not based on pool accepts, simply device work done
(and WU: was added recently)

Same problem with BTC guild, but only on a rig with one 6950, the others alright with 5850 and all have cgminer 2.4.1. On the website the numbers seems right. I will upgrade the cgminer when I upgrade my mining build, for now an debian sid from nfsboot.

Yesterday all servers went to variable difficulty and GBT (not that GBT would affect you).  What version of cgminer are you using?  I'm curious if this is a problem with old versions of cgminer or something else.

I am still using 2.4.1 and I am unable to upgrade. I think that may be the problem

All servers have been updated for dynamic difficulty now.  I've changed the parameters a bit to make the difficulty a little less - it now targets 12 getworks per minute in 3 minute windows (as opposed to 8 getworks per minute in a 3 minute window) ... meaning your difficulty won't be as high as it was on the dynamic test server at a given hashrate.

Let me know if there are any problems.

I will be taking diff10 and the dynamic server (port 8437) offline at some point, please take them out of your config files.  Diff10 is repointed to us1 already, but the dynamic test server will just go poof at some point.

For what it's worth, on the dynamic us3:8437 server, I was seeing a total "U" value of 8.  After switching back to the regular server, the total "U" value is 16.

That's perfectly normal, as you are submitting less shares at higher difficulty. That's precisely why there's a WU column instead to compare and they're about the same within margin for normal variance over that time frame. Note they're *all* supposed to be variable difficulty by now as you can see since your U and WU  don't match, displaying that.

I was just thinking since the servers are set to give out 12 getworks per minute now vs. 8 getworks per minute on the old dynamic test server, that I would see a new "U" value of 12 (instead of the 16 that I'm seeing).

I don't think the estimation from the server will be perfect to give you exactly the right number of getworks. It will only ever be approximate within a range of timeframes. If you run cgminer 2.7.6 it will show you what diff shares you are submitting now.

Looks perfect. Note how the WU is identical on both counts, and that the dynamic server is changing the diff on more than one occasion. It will start at diff 1 and slowly converge on the best balanced diff over time.

Inaba, notice what I have reported before how there are 2 longpolls 15 seconds apart on dynamic diff though? cgminer can tell when a longpoll is associated with a new block or just a request for a work restart. This 2nd longpoll still seems wrong.

Does it only happen on the test server or on the regular servers as well?

@#$#@$ data center.  Power went out again.  I've got the new server built in the new data center, I just need to transfer everything over.
