The problem for me is: There was a block which took a long time to resolve, and my mining rig just self-restarted during the process due to my ISP problem, and the reward for that block became 1/7 of normal reward, this has never happened with other pools  Huh

Have had a low reward on a long block from the same issue, 5 minutes downtime = half (or less) the reward I should've got.. always seems to be the case on a 3+ hour round as well :E.

The payment system treats you the same whether you were trying to pool hop or you just happened to disconnect at a bad time. In the long term it averages out because everytime it happens to someone who isn't you, you technically benefit from their lower reward in that instance.

I still don't understand the "Suggested difficulty" field.   Dose it have some thing to do with long polling? If my connection is bad do I set it higher or lower?

It means that you aim for a share with more worth. E.g. a share at difficulty 1 is worth 1 share, 2 is worth 2 shares.. and so on. The difficulty refers to the target set for your hashes. At difficulty 2 there are half as many possible hashes which would contribute a share when compared to difficulty 1.

The reason it's useful is that with a very high hashrate (>2GH/s) you'll find so many difficulty 1 shares that it'll use up a lot of communication and it floods the server with requests.. so if you look for more difficult shares, you still (theoretically) get the same rewards, but the communication with the pool server is lower.

So if I needed some planned downtime and I didn't want to mess up my shares, how would I best choose when to shut down the miner?

Hold the fuck up a minute! If my miners go down for 5 minutes I lose 50% of the work they have done for that block?

I got these things on Wifi Every time a big truck drives by they go out for 20 to 30 sec. What measurement of time triggers the "oh shit he's a pool hopper fuck him over" device?

Right at the start of a round, i.e. when a block has just been found.

On a longer round, yes - the score is based on an exponential function with the round time as the exponent. It's scaled by a factor "1/C", but on longer rounds this will dominate - check your score under my account. More info found in the link given above ( https://bitcointalk.org/index.php?topic=1976.msg50002#msg50002 for your convenience). The longer the round, the more important staying connected (and submitting a share close to the point a block is found) becomes.

I find this system very convoluted. Clever but convoluted. Do other pools use systems like this?
The network has gained 50 PetaFLOPS in the last few weeks so I'm having a hard time telling what pool works best for me.

Two easy options come to mind:

1. keep an eye on blockchain.info and take your miners down when you see Slush get a block.. it updates automatically and there should be a fairly short lag.

2. Keep refreshing the stastistics page until you see "Current round duration" reset.

Since 1 is less likely to cause issues for the pool.. I'd go with that Wink

Since most pools use systems which discourage hopping your best bet is to leave your miners on a single pool (or point each of your individual gpus/whatever at a selection of pools) and leave them alone. If you're that bothered by the variance you should pick a PPS (pays the same per share everytime) pool.. although in most cases you'll pay a higher fee to the pool for the privilege.

Questions within questions... I'll work it out though Smiley

I don't think PPS actually makes much sense for a pool. HHTT is just switching away from it as the pool funds rand down to 0 and people weren't getting paid.

So....what's going on? I started up my miners after noticing they had shut down for some unknown reason.  Angry

At first, they weren't registering any work at all. Now the site says down for maintenance and to come here for info.

Well....I'm here! Where's the info?  Huh


EDIT:

NM....it's all up and running now. No idea what happened there, but all is well now  Grin

In long run this does not evens out, my ISP's network is not that stable, I often get that kind of network blackout for a while. So, for most of the blocks that took a long time to solve, I will get poor payment. Since this pool is not big enough to shorten the block generation time, they often have blocks that took several hours to solve

And I never really understand this pool hopping thing.

Suppose the pool has generated several blocks in a very short time frame, is it the time to switch to another pool due to I expect the pool will become unlucky in the next a few of hours?

Suppose the current block has not been found for 2 hours, that means all the other pools also have not found a solution for 2 hours, how could I make my chance of finding a block bigger by just switch to another pool?

Isn't this the same as forecasting which side of the coin is up after tossing a coin?

No.

Still no.

Yes. Pretty much, anyway. If you want to understand how pool hopping affects your earnings, try:

I'm still getting the "No connections could be made because the target machine actively refused it" error in guiminer

It's only when I use it through my vpn, which I consider essential for using the internet.  Why is my VPN fucking this up?

I downloaded the latest guiminer before I made this post and am still getting the error.




Slush? You around bro?  Any idea how I can fix this?


I'm pretty sure it starts hashing automatically after a few minutes of getting the error.  I'll report back.

Add this in the server.ini of guiminer.

restart guiminer, Try the alt server. All your setting should be there still.

Code:
        {
            "balance_host": "mining.bitcoin.cz",
            "balance_token_url": "http://mining.bitcoin.cz/accounts/token-manage/",
            "balance_url": "/accounts/profile/json/%s",
            "host": "stratum.bitcoin.cz",
            "name": "slush's pool(IPv6/alt)",
            "port": 3333,
            "url": "http://mining.bitcoin.cz"
        },

Thanks so much!  Smiley Worked first try, hopefully no errors in the future.

The problem is back.  Same vpn server, really pissed.

Hardly anyone speaks English on this forum.

I understand this pool setup something to prevent pool hopping, but if pool hopping itself does not provide any benefit for miners, why should miners do pool hopping at the first place? And if they seldom do this, why trying to prevent this?

Again, nope. The score method reduces the effect of pool hopping significantly, but does not prevent it.

..... but if pool hopping itself does not provide any benefit for miners, why should miners do pool hopping at the first place?
If you're engaged in pool hopping, you'll earn more per share than full time miners - last I checked this figure was around 20% more, but it's probably a bit less now.

And if they seldom do this, why trying to prevent this?

If pool hoppers earn more than fulltime miners, then fulltime miners are earning less than expected - by about two percent when I checked last year. If you prevent pool hopping then everyone can earn the same average payment per share. PPLNS, DGM, PPS and PPS-like methods are fair in that over time you earn the expected amount per share submitted. Proportional methods will on average pay more to strategic pool hoppers than to fulltime miners.

If you want a more in depth explanation I encourage you to read the posts to which I directed you.

FINALLY I can reply Smiley

I have a question and a suggestion.

1. Is it better to have say, 5 separate workers, 500mh/s each, on difficulty 1, or make them all one worker at 2500mh/s and make them difficulty 2?

2. Also, Slush, this one is for you. Would it be hard to implement a feature where it emails you when a worker is idle for more than xxx mins?

Thanks, and thanks for the great pool Smiley

I have been on some conferences and I also took a short break in recent days; that's one reason why I didn't respond to many questions here, on FB page and from email.

The second reason is that it began impossible to respond to everybody, because in recent days I had a storm of emails of any kind. I even have many phone calls a day "where can I buy ASIC and is it worth the money?". Once I realized that I spend over three hours a day just by responding to common questions, I decided to stop answering such questions at all. Maybe it sounds impolite, but pool now has over 160.000 registered people and answering their questions distracts me from any real work. In contrary to situation a year or two ago, now there're many manuals, howtos and FAQs about mining, ASIC etc so I don't think answering everything personally is needed anymore.

I'm writing regards to recent issues on pool. You may notice that there're some consistency issues on Stats page, e.g. rounds 17370/17371, website also sometimes hangs with "in maintenance" message. The reason is overloaded database; just in last month, the traffic on website quadrupled, much more people started using some monitoring tools polling the API from their widgets, others are refreshing profile page again and again; the traffic on website is just crazy. This *doesn't* affect mining, because mining backends are completely asynchronous - shares are queued and registered to the database lazily, which also explains these inconsistences in statistics page for very short rounds.

On friday I ordered new database machine which will take such load, which was prepared yesterday. I'm finishing the configuration and at today's night I'll migrate database there. There'll be just a ~15 minute downtime of website and few-second downtime of mining (backend restarts). I believe that it fixes all website issue.
