Ztex software has long polling. I have now 0.14% stale rate with 1k2 GH FPGA power. Looks like Doc killed the bugs

Doctor Haribo, Curing the bugs that ail you, one line at a time

[DrHaribo]

Thanks for all those votes of confidence earlier.

New version of pool backend up today. Big performance improvements. GPUmax took the server to 220 GH/s total and I could barely see any load.

Last problem to fix for the pool to work better with GPUmax is to get better in sync with the big pools. GPUmax uses their long polling regardless of which pool they are mining at (it doesn't watch our long poll at all). This has to do with how work from different pools gets sent through GPUmax to the same miner, and a long poll signal from them to that miner would cause it to throw away all the work, regardless of which pool it is from.

Anyway, that's a GPUmax specific problem. For normal miners we can now take a very high hash rate. So fire up every machine you've got!

As always with big changes on the system, please let me know if you notice anything wrong.

where did bossland go?

I want to have my avatar on the forums display my speed I am pushing through bitminter but when I copy and paste the code I get a blank box.

Never mind I figured it out just a dumb moment.

115% ?

[ZodiacDragon84]

bah. we'll git'r done without him then.

[jake262144]

Wow, 0.08% stales... I think I'm in love.
Thanks for the hard work, Doc.

bossland has returned

Personal best record I think. 1 4970, 2 5870's

Very nice :-)

You're hanging with my 5970 and XFire Mobility Radeon 5870s, which are presently doing a total of 1007 MH/s.  Sadly, two Mobility 5870s go about as fast as a single desktop version 5870.

For my bitcoin username, my BTC reject rate is about 0.4% but it's 5.5% for NMC.  I have 2 x 5830's a 5850 and a 6950, all running about the max overclock i could get.  You know of any reason my NMC reject rate is so much higher than my BTC reject rate and the pool reject rate?  Are my overclocks not as stable as I think they are, lol?

looks like fox has unleashed something f*****G awesome!

Thanks for the hard work, Doc.

Glad you like it

For my bitcoin username, my BTC reject rate is about 0.4% but it's 5.5% for NMC.  I have 2 x 5830's a 5850 and a 6950, all running about the max overclock i could get.  You know of any reason my NMC reject rate is so much higher than my BTC reject rate and the pool reject rate?  Are my overclocks not as stable as I think they are, lol?

Reject rates now seem very different from user to user. Currently I have 12 (0.02%) rejects from 36 hours of mining. That's on BTC. On NMC I have 1 reject (0.01%).

High rejects could be not only stales but also invalid shares due to overclocking too high. The BitMinter client will show a count of miscalculated proofs of work (next to the bomb icon), and not send them to the server. I believe DiabloMiner also detects miscalculations. What happens is the CPU double-checking the proofs of work generated by the GPU. Not sure about other miners. Some miners might send them to the server which would result in rejects.

The NMC rejects always or often being higher than BTC rejects might be the miner ignoring long poll notifications because it sees the bitcoin block isn't changing to using a new parent block hash. BitMinter client won't do this, and I believe new versions of cgminer won't do it either. Or do you need to use an option for it to work well with merged mining?

Hmm, can't think of any other reasons for high stales at the moment.

[SgtMoth]

my stales for btc have been running .07% and honestly ive only seen one or two on nmc

[marks1976]

I run .02% stales between 2 cards in 2 different machines.

Possibly.

Rejects are either:
- stales (hash is valid but the underlying data is no longer current)
- invalids (card generated incorrect hashes that were never valid)

Hopefully someday Dr. H can split out rejects into stales & invalids.  In the meantime you could drop clock rate on one card to stock and see if rejects are lower for that card.  If so the difference is a good indication on the % that is from invalids.  The rest is from stales.

Newer version of cgminer does better w/ stales on merged mining pools (due to improved handling of LP).
Your internet connection, and latency to the pool will affect stales (but not invalids).
Aggressive overclock increases the rate of invalids (but not stales).
Having intensity set too high increases stales (but not invalids) if used w/ "submit stale" option (in cgminer) due to increases batch time.
