[ANN][AUTO-SWITCH] Profit-switch auto-exchange pool: CleverMining.com

[_r2h]

Mining for 1 hour, stats -- 829Kh instead of ~2.4Mh.

Because it's an average.

Well I am happy with 100% rejects as well as long as I am getting paid well. I am here since 18hours for testing the pool for a couple of days, and we will see.

Btw a little explanation on rejects : Your share is only getting rejected when you send in a share which is not actual. Actually the pool needs to notify the miner that we have a new block/coin mining and stop mining the old one. When your miner is not getting notified then happens the reject. I am sure you will be able to improve the reject ratio, but probably you will need to recode some parts of the stratum-mining, and open and EU server. You need to force the stratum-mining to notify the miner every time there is new block or new coin being mined, maybe you can make make some debugs with sniffing the packets when the stratum fails to do so.

Difference --> 0.00295 BTC
Not a completely negligible difference.

I would call that negligible.

Far from negligible.

It's negligible compared to the statistical variance of mining luck over the time period measured. If that difference persisted for months, then for sure not negligible. But over a period of three days it is pure statistical noise and doesn't say anything conclusive one way or another.

Yes.

Mining for 1 hour, stats -- 829Kh instead of ~2.4Mh.

If you haven't been mining for the full clock hour then last hour average will show lower value. It basically sums all shares submitted by you within this hour and divides by 60 minutes. Please take a look at real-time chart or wait for the full clock hour (and then 10-20 mins to stats regenerate and website cache refresh).

Yes, of course miners are notified with new work about every new block and on every coin changes. There wouldn't be much hashing if they weren't receiving new block notifications.

While waffle had zero rejects for me. I'm getting an average of 3-4% here. Maybe try different settings guys? It's odd we have such a big gap among everyone on what their reject rate is.

[SanderHelgesen16]

this pool is getting big!  nearly 3k MH/s

[KC82]

I've been seeing the lower reject rate in my stats for a couple of hours now. It is still a few percent but not double digits. Assuming the pools hourly stats maintain a good 24 hour performance rate, I'm happier with the lower reject rate.

[evolvia31]

@terk:  Very good you tweak to reduce reject shares.

Actually i have only 1-2% reject to compare with 8-10% this morning.

very good job thanks a lot.

[CoinBuzz]

@Terk: I believe when pool hashrate goes very high, it cant point all of its hashrate to some small coins because it would produce reject shares or produce very high amount of coins that selling them is harder in market.

What do u think?

[Wipeout2097]

@tyj8tim: Share difficulty has nothing to do with reject percentage. Or with overall profits, or with anything that matters.

I actually have my doubts on that with a switching pool.

I agree that IF we mine at a pool that only mines one coin, then the variance will average out and you will see a steady payout after a few hours or 24 hours.

However, at CM we get a lot of stale rejects. And I'm assuming these are not all counting towards our hashrate (correct me if I'm wrong). From my understanding, stale rejects are the ones that's too old because the pool already pointed to the new block. So if someone has a ~10% reject on average, that means ~10% of the time when he finished his share, the pool already moved on and his calculated shares are useless. This is especially a problem for a pool that's hopping around and getting into block times that's less than a minute or even 30 seconds.

So IMO, by lowering the share difficulties, you can shorten individual miner's share round time and minimize the probability of submitting stale shares.

This is a valid point that was discounted by noisy posters.

It doesn't affect everyone the same way. For example, if one is far away from the pool (e.g. a miner in Eastern Europe connecting to U.S. West), a pool becomes often unusable.

Of course, end profit is what matters and there's always a balance. Some suggestions are zero-sum, or include extra hassle and cost for pool operators . However, if it's good for you, leave it at that and don't speak for other people.

[UdjinM6]

hmmm... looks like rejects %% are really going down for me, I'm increasing my hashrate here to 5mh/s for some more tests.

btw, congrats to dev on reaching 3gh/s and hope they prepared for some more!  

[Red- Beard]

Hate to be the necrohippoflogaphiliac here, but I'm still getting really high rejects (even after the tweaks you did), also my hashrate is all over the place when I know my CGRemote is showing a cool 2.0 MHash.

Please take a look http://www.clevermining.com/users/1M6ZozLvZoRhD6NLhtfcVB2aWcgtZhUG8w\

Ideas?  This is a rig I've mined with for months, and I've never had a high reject rate like this.

Pools "measure" hashrate via shares accepted.  Accepted shares have variance, so your hashrate will flux.  Doesn't appear your reject rate is all that different than the pool's.  What is your avg reject % on cgminer?

Stales at 0.65% (about what I'd expect my total rejects to be)
Rejects 18.75%.

I almost never see my rejects below 10%, and they often spike to 25-30%.

Mind you I've only been mining this pool for about a day, but I'm really trying to give it a good run before making any long-term decisions.  Just want to be sure I'm not bleeding shares.

Edit:  I saw your twitter feed, I'm trying to lower my intensity slightly (as per someone's suggestion on there) to see if that helps.  Bumping up from 19 to 20 was a change I made a few days ago, so I'll try at 19 and see if that helps at all.

[martynw2000]

 Bumping up from 19 to 20 was a change I made a few days ago, so I'll try at 19 and see if that helps at all.

I reduced my intensity by 2 on all cards running more than 18 (20 to 18, 19 to 17, 18 to 16) and that really helped a lot. Was getting ~15%, now averaging ~6-7%, and that was before Terk fiddled with the settings today.

what effect did that have on your KH/s? is the reduced reject rate proportional to the reduced Kh/s? i'd be trying to keep my KH/s as high as possible.

Kh/s was lower of course... but not by a huge amount. My two 7950's were both running at about ~670, now they're running at ~630, and possibly a bit cooler too. So I lost 40 Kh/s, but it halved my reject rate. So I'm happy with that.

[jbass350z]

Why is the reject rate so high (it is not fixed!). Is it the particular coin that is being mined?

[KC82]

Yeah, the reject rate seems to be back into the double digits.

[pindis]

Yeah, the reject rate seems to be back into the double digits.

i-13 = 0-2% rejects (located in eu) i-18 = 13 % rejected.. meh
