And having admitted it proudly seemingly knowing exactly what he was doing!


An excellent point of course..  I might have omitted that part of the equation simply to make a stronger point (in the absence of someone else who knows what he is talking about) .  Or I might have simply neglected to account for the increasing difficulty.  I'll never tell (but you could look a few pages back to see if I was aware of the litecoin situation.)

Looking forward to pool rejection rate statistics!

Update, there should be another significant litecoin difficulty increase in less than one hour!

Yep, on my list for today.  It wasn't an issue before so we hadn't been showing it   Until I can get it added, overall pool reject rate is currently going between 2-3% overall.


Everyone is on the new servers (about 12 hours now), minus about 3 miners (about 15MH total) that are using a custom port for people that couldn't mine on 3333 (which I honestly forgot about until now)...  I'll switch that over today.

As for phzi, certainly didn't mean to call anyone out on the miner tweaking, just noticed it was happening, and wanted to fully explain what was going to happen with the new software (and why).  I honestly expected a bit higher than 2-3% overall (expected 5-7% and thus more complaining on the forum), but 2-3% seems to be taken really well.  From his perspective, everything he did made sense.  Kept tuning the card further and further without getting any rejects (which is pretty much exactly what you're supposed to do), and everything was working fine from his side (shares accepted, blocks found, etc).  Its just a matter that due to the way the stratum endpoint was handled, it really should have been telling him (rejects) that what he was doing wasn't as efficient as he saw it as (for the pool as a whole that is).  My guess is there are a decent number of people in the same spot, he's just going to take the brunt of it because he's here a lot, and posting a lot


Unfortunately, over the last 3 days there has also been close to an equal rise in difficulty   LTC profitability has increased only marginally in that time (5%?).

poolwaffle, it might have been mentioned before, but is there any way we can get average rejection rates listed next to average hash rates, for both the total pool broken out by day, and individual miners broken out per worker?  Such information would help drive us all to increase our efficiency collectively.

Thanks for sharing your settings and experience - I've got a couple of questions (please forgive me if they're silly due to my newness to all this!):
1) I am using xubuntu and cgminer 3.7.2 - can I use this xi with this?
2) Given that the "power" of the graphics card is used for mining does the fact that you can play movies etc mean that you're missing out on some of the spare "power" for mining and hence there is more hash/effective work that your setup could be doing?  I'm using "power" as I don't know what to talk about in terms of watts, hash to mean "processing power!

Not sure, don't have a means to measure it. Should be pretty low tho, the highest voltage running card is 1.093, the rest are spread between 1.050 and 1.070 and quite cool even in the hot weather around, don't reach 70. My point is something waffle said: cranking intensity up gets you stales, because the card has no time to submit stuff, on the other hand, having the same speed achieved with lower intensity makes the shares gets submitted very fast, thus the low rejects. Also observation between the 2 configs - one makes even the mouse lag, the other - you can freely watch movies and can forget there is even mining going on.

Edit: just checked the other 3 rigs with 280x on them - the highest reject is 0.27%, the lowest - 0.07%

Not sure why you thought I would be disappointed about anything concerning your configuration, as all I was pointing out was that your observation did not necessarily prove all that you stated it did.  What is your MH/s per KWh?

Pm'd.

Sorry to disappoint but:
- I'm on EU, the first server that was updated
- Having lot of stale shares and submitting them, always accepted (my expire is set way too low, have to set it again to high)
- Producing enough - 670khz per 7950, 91% work unit efficiency

It is just good config. Yes, I can run this card and achieve the same speed on t1, I20, tc 24000, but then I get many rejects, instead I'm using t2, xi4, tc 8192 and works like charm. It is all about optimizing

0.1% rejects overall, same config as before, that only shows it was done correctly

Note : I graph directly against coins earned instead of mhash or reject rates.

Yeah it seems so, i'm seeing increased rejects, but profits seems to be going up.
I know its too early to tell but let us compare tomorrow against other pool.

Guys, i'm on 0.5% rejects on SEA server. What's yours ?

I believe you are mistaken about how you are justifying your actions by claiming that you created few orphans.  Depending upon the server code, all of the very many stale shares produced by your miners and submitted to the pool server only to increase your total share count, would never even have the opportunity to be passed on to the coin daemon, but just accounted for in the database.  Orphan blocks are created by entirely different circumstances.  Can you comment, poolwaffle?

Dishes, you're missing the point entirely.  Phzi has admitted to having his equipment [over]tuned to submit the maximum number of shares possible, regardless of whether they were valid (not stale).  He was diluting the value of all valid shares which is the basis upon which we are all paid out, as only valid shares can be used to solve a block, thereby taking a greater portion of the total pool earnings than was actually generated by him, as he was being paid on the basis of his total shares, however worthless to the pool.  So for all those miners who had tuned their equipment to produce the greatest number of valid shares, phzi was knowingly taking profits out of your pockets.  (In fact, had someone created a modified miner to take advantage of this pool vulnerability, they could possibly have sapped many more profits away from other pool members, depending upon the server code.  And there are many smart people mining these days, so I would not be surprised if there were a good chance this was actually happening.  poolwaffle, did anyone's reject rates shoot up significantly higher than 10% immediately following the changeover?)

So this stale share handling change on the pool servers does not increase phzi's profitability at all, it increases the profitability of the more productive members of the pool.  He will see a decrease in profitability, as he can no longer leech profits from other members of the pool.

Phzi, I will not speculate upon whether your actions were ethical, as my own personal opinion of most human beings is rather low (poolwaffle excepted by my impressions of him thus far).  I think that most of us will do such things if there are no real consequences when found out.  But openly admitting it and being proud about having taken advantage of others is a rather strange twist.

Poolwaffle, as many as complaints that might come in for making this change, it was the proper thing to do so as to encourage those underperforming members of the pool to learn to tune their equipment, and properly place the fiscal burden upon them for failing to.  The old system even hurt you too, as the pool has been showing lower returns per hashpower than it could have been, and ranked below other multipools as a result.

Today's profitability is through the roof.

BTC / 1MH
0.00839364

I am still getting 0% rejects and at the same hash rate. Not sure whether i need to reconfigure any settings or not, but everything looks the same to me.
WU is about 91% of hash rate
Im using Singapore server.

So you're seriously bummed out getting 2.5% rejects? Even though the server changes help your profitability overall?

Oh, I knew what I was doing by cranking my miners the way I did - but as I said, I have discovered many blocks for WafflePool, and a rare few were orphans.
Ya... I still think that was one of the best parts about wafflepool - haha.
Indeed.

I am getting around 2.5% average reject rate now after re-tuning for the new reject profile.

Looks like the new stratum server is costing me overall about 2% in decreased hashrate, and 2% additional rejects (very short sample period so far, mind you)

Guess this was the point of these changes.  Not overly pleased myself.

I am running with the same configs as prior and still getting under .5% reject rate. I dont need to restart each miner/worker in order for new stratum connection to be established, correct? If I am wrong please let me know as id like to be on the best/right connection.

it was a scam and not a promotion, and i hope they will get 0 out of it after it ends. i mean, who will ever say he is paying you +$50 for your first week and next day it is +$25 because FU. [random potato pic here]

I will be back with your US servers once you swap to the new stratum and when Ghash's promotion is over.
 

after all, it probably was not a bug, but a feature to counter chinese cyborgs.
