All is well and the monster block has been solved!

That's great news! Just four days ago I switched to here from Continuum pool which had a dry spell for 10 days. So I thought I brought you guys the bad luck, but finally my first block in EMC is solved!

By the way, the block stats on the web site say it's been 15170 days for this block

Block has been processed.  There is some display issues with Block Stats (Block duration is out of bounds and share calculation is way off obviously)  - I will get that fixed this evening, but it's due to the proportional vs scoring.  Since we switched to scoring the block stats calculation exploded; I had forgotten to check that.  It's just visual issues not data issues, so nothing is lost.

Stats are correct under My Account though, which is what really matters anyway

Here's Block 19 round data:

I'm having sad thoughts about this pool.. It seem's we've hit a difficulty where we have to low hashing speed.. In the long block, I sent 17096 shares in for a 0,14324500 BTC. That is a loss of 0,34862951495985664 BTC if I'd been using PPS..  I too had a big dry spell from Continuum. With to low avg solving rate.. this just won't be enough to keep at it.

Not to talk about the 6% rejected shares.. >_<  Guess it's time to end this trip.. or move it for PPS again. 340MH isn't cutting it..

Suggestions anyone?

This long block makes up for the 7 short blocks we had. In fact, without mathematically calculating it, it looks like EMC has been lucky. It all averages out.

What's the payout system...?

[cengique]

US pool seem to be down..

Long blocks happen.  They happen for every pool.  Short blocks happen too.  it all evens out in the long run.

However 6% stales is very high.  I would switch for that reason.  I am getting 2% stales, a little high compared to ArsBitcoin (my backup pool) where I am getting less than one third of one percent stales.

A long poll problem perhaps??? Inaba?

Start mining full time on Eclipse after it hits 300-500gh/s hash rate, at that point variance swings will be relatively low if everything is configured properly (even at 1.6m+ difficulty)

It's also one of the few pools offering SMS notifications so that's a unique perk.

[village.idiot]

Up and running again.  Yea!

[Inaba]

Boy that bitcoind is really causing problems.  I am going to approach it from a different angle that should keep it stable and reduce rejected shares but I need to figure out what's going on with the current implementation. 

I am sorry that it was down, I thought I had the problem with the system licked and it was suppose to notify me if it went down, but I did not get a notification so I didn't notice it right away. 

Going back to the stable Bitcoind shortly and that should take care of any issues and I will work on the stale share thing this afternoon.

[Inaba]

Can you guys let me know how the stale shares are going for you?  They seem to be decreasing for me quite a bit.

I was running at a rate of 2% stales with a peak of 3% stales.  Recent results seem to show a 1% stale rate.

[Inaba]

Good deal.  I will work on reducing that further.

We solved a block, it's processing now!

[bacon strips]

Hello, I switched here from Continuum pool when it shut down.  I just got the newbie restriction lifted from my bitcoin forums account or I would have posted sooner.  I am putting all my 885 MH/s towards this pool.  I am just happy to know that Meni's scoring is being used to prevent pool hopping.  

My user name on EMC is minecrafter.  I found one of the block that the pool found so naturally a would like a table under top miners that has the top block finding miners.  

Edit: I did not notice the hall of fame. 

[WebMonkey]

it's already there. (click on hall of fame)

unfortunately, i'm not on it.

not on the top miner either (bumped off a week ago or so)

How high MHash does one need to make better profit then PPS?

Est. Reward: 0.28700100 / PPS 0.00002877132165184 (10% Fee) = Shares submitted 9975 Before it's lower then PPS value, My Valid shares 11079 Value Per Share ~0.00002590132165184 (~18.97% Fee)

1 d 20:39:07 = 44h 39min = 160740 sec / Shares (11079) = 14.5s per share * ~345MH = ~5000MH to send one Share..

Does anyone feel like comparing his numbers with mine? How many MH per share do you need?

Just having a math crunch munch.. ^_^

This is for block 20.

I'm not sure I'm following that math, PoulGrym, are you saying you'd need 5 GH/s at a minimum before it's more profitable to do score or proportional?

Has nothing to do with hashing capacity, completely depends on the duration to find the block. And PoulGrym, on average, you should get better than PPS because the fees are less. I hope I didn't misunderstand..

The probable number of hashes per share (which is what I assume you mean, from your working out) is proportional to difficulty.

P(hashes to win) = difficulty*(2^32)

at difficulty 1 (which most pools run on) = 2^32 = 4294967296 hashes per share.

This is regardless of whether it's proportional or pps.

However if you want to know how many extra hashes you need to make up for the fact it's pps (assuming pps tax is 10%) that will be simply:

2^32*(1/0.9)

= 4772185884.4 hashes = approx 4800 * 10^6 hashes or 4800 Megahashes.

Note that the result relies on nothing other than the pool's difficulty setting and and the PPS tax. Any time you do the figuring out you'll always get around 4800 MH.

NB: some confusion arose previously because you used MH to mean both 'megahashes per second' and 'megahashes'.

[PoulGrym]

Nope.. that's only first a fee calc how much loss one does once we hit over the diff share rate.. next calc is how much Hash Calc each share needs. In my ex: it's with 345MH's

My avg Share calc was each 14.5sec and that would make it 5000 MegaHashes In avg to Calc one Share..

You Try.. 160740 sec / #Blk20 Your Sent in Shares = Avg time sec per calc share. Then you put in your avg Rig HashRate  (Mine ~345MH)* the time sec result.  Should be around 5000MH (I guess that is if you run your rig 24/7)

Can we add an avg hashrate per miner for each block??

[Edit] @organofcorti: Great explanation, that was exactly what I was looking for.. If this info could be available in the pools mining area that'd be great. Perfect mining in theory is one thing.. We get all the random factors that pushes this back a bit.

4294967296 ~= 4300MH / 14.5 = ~300MH Per Sec, So my avg Hashing speed for BLK#20 was 300MH if my calc is correct. Still my mining program says it's about ~345MH. Can it be the Rejected %??
