Strange my reject was .1% and my overall difficulty was 1.548 overnight. Some shared did bleed over to US3 not variable but I setup a different worker for variable so that only that worker on the variable server uses it. All in all I think it works pretty good at 864mHs.

After running cgminer all night at 200 MH/s, WU reports 3.0.  I generally saw 2.9 in the past.  It's interesting I'm not sure what it means.

I noticed a higher than average reject rate however.  Usually I get like less than 0.5% rejects but overnight it was 1.09%

Yep now with different difficulty shares, U now only means exactly what it's name is - shares per minute - but can't be compared to hash rates and with variable difficulty shares it makes it even harder to compare it to anything.

The number of interest on your screen is WU:

At 799MH/s you would expect a WU: of 11.16/m per BFL
You are getting 22.5/m for 2 BFL's so doing a small bit better due to luck.

The actual payout will be less than 22.5/m since 22.5/m includes rejected shares.
Unfortunately you don't know what those 11 rejected shares were - so you can only estimate them.
If Avg Diff is a true weighted average then 11 shares estimates to 27.7 diff 1 shares rejected out of the total.
... I've got no idea if it is a true weighted average - though of course Inaba should know - he wrote it Smiley

You can get the total shares sent to the pool from the API in 2.7.1 and later
(it's currently called 'Diff1 Shares' with the 'pools' API command - I've changed it to 'Diff1 Work' for the next release)
Or by multiplying WU: (if you only have one pool) times the elapsed time cgminer has been running.

Every time I see this I think the API needs a diff1 version of Accept, Reject, Stale ... to be added into cgminer ...

Dave3: Those look in line with my testing.  Your speed reads a little high, but it's hard to gauge with only 15 minutes of testing.  How does it look after a couple hours?  What is your time estimation window set at?

The "Minutes to estimate miner Hashrate" is set to 15.

Here's an updated screenshot after it's been running longer.

"my 200 MH/s "rig""

I LOL'd
Sorry man, but as a small (slow) miner myself I found this funny.

I switched my 200 MH/s "rig" over to us3 to test variable diff.  Unsurprisingly my miner stats say 1.

I did notice that cgminer is reporting a higher WU than I'm used to seeing.  I usually get around 2.9 but it's 3.2 right now.  Maybe I just hit a lucky streak.
I'll report tomorrow morning after running it all night.

Yes, it works on the same time frame window as your hashrate estimate, which is found in the lower left hand corner of your My Account page

This is not OK.
Oh, does it zero after a time?
I was expecting it to maybe reset every round or something

The only way that can happen is if you stop submitting shares to any server.  Is the avg difficulty still giving you problems?

This is not OK.
Also trying the vardiff server.
Seems to be working OK, but the avg diff readout has stopped working... stuck at 0.

To be specific, it's the 2nd part of the 2 part pair of roll-n-time and >diff1 shares Smiley

Roll-n-time means you ask the pool for work and can make multiple work items with the one work item you get from the pool
Typically it seams around 10 or 20 work items per single work request for someone in the 1GH/s to 2GH/s range.
Thus you are asking the pool for 1/10th or even 1/20th of the information, thus your requests to the pool for work are also 1/10th or 1/20th of the bandwidth
... and the pool has to do 1/10th or 1/20th of the getwork work for you that it needs to do without roll-n-time.

However, you still find the same number of shares and thus have to send back a share for each one to the pool.

Higher difficulty shares means you are telling the pools you have done more work, so you get paid for more work, each time you send a share back to the pool.
An example would be 2 diff shares.
A 2 diff share means you will only find half as many as you would if you were looking for 1 diff shares.
Since you only find half as many, they get paid twice as much.
As a result, you are also only sending half as many shares to the pool - so again you are using half as much bandwidth sending shares to the pool and the pool only has to handle half as many shares processing ... from you.

However, there is of course also a down side to >1 diff shares, it increases your variance.
However, anyone mining with a high hash rate is already mining with a lower variance than people with a low hash rate - so it's not really a negative thing in that respect - as long as the difficulty shares you are getting are appropriate for your hash rate.

See the posts by the BTC Statistics Squad for details about what difficulty shares are appropriate for your hash rate Smiley
(of course I am referring to people like organofcorti and Meni Smiley )

Think for yourself
I'm really sorry for interrupting or asking such a dumb question, but I seemed to have missed whats the pro with the higher difficulty ?

Will I solve blocks faster ? Will I get paid more ? Will I have less stales ?!

Sorry & Thanks ! Smiley


I don't think it's a dumb question.

My understanding is that higher difficulty shares will take longer for a miner to mine.  So a Difficulty 4 share would take your rig a approx 4 times as long to achieve so the pool will then pay 4 times the amount than it would for a diff 1 share.

So no you won't solve blocks faster, you won't get paid more and I don't know about stales.

The reason for this is for pools to prepare for the high hash power mining hardware that are coming out soonish.  The higher difficulty shares require less bandwidth to and from the pool and less processing power at the pool end.

That's my understanding reading what different pool op's and Bitcoin experts have been posting here and there.  I may be a little off, I usually am Smiley.

Less network and application overhead load for you.

A lot less network and application/execution overhead load for the pool.

I think on average there should be 1 share for 1 getwork at 1diff, but I'm sure someone can correct me if I am wrong.

Stoppots: The variable difficulty is for every miner of every speed, that's the  beauty of it.  If you are less than about 500 MH/s, you'll get 1diff shares almost exclusively just like the current servers, but if you're > 500 MH/s, your difficulty will start going up according to how fast you are.

Not sure if it's a problem, it looks strange though. Connected to the var. diff. server.
I get the "New block detected on network before longpoll" message like 10-20 times, every time it shows up. Anyone else? Using CGminer 2.6.6 (Higher versions make my gpu crash and can't recover).

Hi Graet, perhaps I am being overly observant watching out for conspiracies again.

When did the change to no longer sticky the top 10 pools in the pools section occur?

Bitcoin Forum > Bitcoin > Mining > Pools

Seems like less than a week ago they were still stickied. Am I safe in assuming this is directly related to EMC's growing popularity and the soon to be added Variable Difficulty Shares(or similar shortened version) to EMC's subject title?

EDIT:
Decided to use the search feature and came across this thread.
https://bitcointalksearch.org/topic/top-10-pools-stickied-103313
yeah more likely diblo-d3 cant be bothered anymore, no-one responded to that thread or 2 similar in meta forum :/
