For some reason I'm getting high reject rate on US2, 1.1% over the past couple of days. US1 however, has been almost 0.
I run rotate every 20mins between a few pools.

If you run a regular rotate between the pools? are you not going to get a few naturally occurring rejects just because it can't submit a share to the pool it's connected to when it changes over.

I saw the same thing so I switched to us1 and it went away.

I'm mining at the diff10 server atm, but I'm not on the top miners list, although I should be. Is it not included in stats?

Same here.
Inaba mentioned earlier that the top miner list is not accurate because of diff10.

No, cgminer keeps the right shares in the right place. This is unique to US2 only.

I think it may be related to the fact that there is a botnet connecting to that server and flooding it with cpu miners.  I'm looking at ways to fix it without harming the legitimate miners.  I have an idea that I will work on tonight or tomorrow.  In the meantime, using US1 or US3 (or 10diff) should solve the problem.

You could set a minimal limit for a miner speed =), CPU's are usually no more than 50-90Mhs

Seems that [Auto Payout] does not work. Anyone has same issue ?

It's been working for me.

I wonder if efficiency wouldn't be a better way to find cpu bot nets.
It seems like the big disadvantage is the deluge of getworks for very few shares.
Then again if something like 100% efficiency was required I couldn't run the diff10 pool. I really am a bit low to run on it anyway so there is really no harm in it either. This could possibly make some people upset if their miners do not suppor rollNtime. I would assume though that for everyone it would be a pretty good way. Possibly I am missing something with this thought though.

People using backup pools may find they can't use EMC as a backup?

[Inaba]

Why wouldn't they be able to?

[kano]

Why wouldn't they be able to?

It was my answer to his suggestion.
Shares would be rare, and getworks are often higher than accepts for backup pools.

i'm confused... why would this be so?

[Askit2]

Because a LP comes along and drops the work with no submission.
Also every block your miner could grab work from a secondary pool but never work on it.
Like I said there is likely something I was missing.
a 50-100Mhash limit would effectivly do the same in a way. Hopefully Inaba has a better idea.
As a backup pool though their effective hashrate should be fairly low too. I wonder if cutting off at a 10% efficiency would work, or less then 10% efficient at some overall speed like >200Mhash. Then again that might encourage tons of small accounts.

Inaba the last email I recieved for a block solve was Tuesday early AM for me. Block 196076. Possibly I upset the helper monkeys. If you could let them know I am sorry for whatever I did I would sure appreciate email notifications.

A few days ago I received my first ever EMC Payout notification, then shortly after that I stopped receiving Blocked Solved notices.

Since this is one of the very few pools that has already put higher difficulty shares into trial, I quote my post from another thread that will hopefully help direct your further efforts towards this:

60 seconds per share will be way too infrequently if it's a static value. The variance will be painful. A minirig is the current highest hashrate device available and produces over 350 shares per minute. You would be setting current users to a difficulty of 350. The problem with that is the variance is the square of the difficulty so the variance will be much much higher and it would take weeks to get a stabilised return, when you are already capable of coping with hundreds of shares from the current minirig owners. To not make variance any more painful at high hashrates, make the share return rate proportional to the square root of the hashrate instead of a constant. So a 1 GH/s miner currently returns a share every 4.2 seconds - if you make the 1GH miners difficulty 10 as a baseline, then you make 10GH miners sqrt(10) * 10 ~ diff 30. And you make 100GH miners sqrt(100) * 10 ~ diff 100.

Note that the maximum efficiency of cgminer is about 70,000% with the current code, but likely limited to about half that but even then, >30,000% efficiency, combined with higher difficulty shares means most pools would cope with dramatic rises in hashrates (read ASICS) without any new protocol.

If anyone wants to play around with 10Diff shares:  diff10.eclipsemc.com port 8337

Give it a shot and see if anything breaks!

This is working very nicely for me and I think (variable) difficulty targets are way overdue. One thing which I have noticed, though, is that there seem to be 2 longpolls for every block change, between 15 and 20 seconds apart.

ckolivas: Only on the diff10 server or on all servers?  I'm not sure why that would be, that's kind of strange.

With regards to the block solved emails.  The helper monkeys that handled the block solved emails apparently went on strike.  However, the plans to picket the EMC headquarters ran aground when a barrel of banana rum was uncovered in an old storage crate containing the picket signs.  The monkeys were found in a drunken stupor at the union office this morning... I agreed to ignore the issue if they would get back to work under the current conditions and they reluctantly agreed.  As of 10:35 AM CST, the helper monkeys are back to work.

The beatings will continue until morale improves.
