surpassed 20 GHashes/sec for a while now. Maybe you want to update the thread. Smiley

Once a transaction has 6 confirmations, it is extremely unlikely that an attacker without at least 50% of the network's computation power would be able to reverse it.

I've decided to pull my nodes from the pool as of Jan 22. Since joining the pool on Jan 6, I have received about 5 BTC/day for a total of ~80 BTC, and in that time, I found 4 blocks for the pool. This morning I found yet another block (for myself, this time). Maybe I am just lucky, but I feel like the 80 BTC I've earned is well behind the 200 BTC I would've earned all on my own.

May I ask how you compute your expected gain ?

Unless I'm mistaken, this is the expected gain for mining all by yourself. I compute my expected gain by finding how much of the total computing power of the pool I have, and how fast the pool generates blocks. I didn't try to prove it, but it seems logical that this number would be somewhat lower.

Slush,
Something strange is going on.
This is the second day now that I've woke up, checked my stats, and it shows that I've produced 0 shares....even though my miner's are running and finding hashes!

So I restart my miner, and still, no shares showing up.
So again I have to restart my miner, and nothing is showing up.
Just restarted it a third time, and finally it's showing up with submitted shares.

Slush, the two workers I'm seeing this with are:
fairuser.desktop
fairuser.ATI5770

How can I be producing hashes, and the server is not recording them.
Because of this, my payout has been dramatically cut...which is not cool.

Since this is happening on two different machines, I certain it's a server side issue.

Any ideas?  Anyone else seeing this?

When I run BitCoin on my laptop it gets about 1800 khash/s, when I run the cpuminer and connect to the pool I only get about 800 khash/s.  Anyone else's speed slow down when they connect to the server?  Is this normal or do I need to fix some setting?

Is your laptop dual core ? Cpuminer doesn't use more than 1 core unless you tell  it to.

Yes, it is dual core, so that must be the problem.  However, I just looked at the commands for minerd and didn't see anything for specifying the use of both cores.  Do you know how to do that?

I started another instance of the program and both of them ran at about 800 khash/s.  Setting two threads had the same effect, 800 khash per thread, but is more convenient than starting two instances.  Thanks for the help, I appreciate it.

It just happened again at the beginning of round with block #104271.
Shares were being "accepted", but not showing any credit on the website, and I had to restart my miner before the server started showing them.
Very strange.

UPDATE:  So we just started a new round again (#467), and my miner is still runnings, says it's ~ 175,000 khash/s, but doesn't get any new "accepted" after the round begins.  This is very strange.  I shouldn't have to restart my miners at the beginning of every new round!!!

UPDATE 2: My miner is no longer getting any active shares/hashes since I reboot my PC and restarted my miner.  It appears to be getting the "getwork" request, but after 5 minutes I have not gotten a single share.  I also just found a the solution for the block on one of my miners thats working. w00t!

Slush, did you change something?

UPDATE 3:  I created and starting using a different account and worker on my 3rd PC w/ the ATI 5770.  Right away I started getting "accepted" shares that are being accepted and counted on the server.  So, Slush, why is my account with 3 active workers having problems?  My two workers seem to be running fine, but the third worker is just getting a bunch of "getwork" request that don't have answers....which leaves my card doing a lot of work for nothing.  Did you add some type of new restrictions, because if you did you just broke my setup......which ONLY HAS 3 MINERS! Sad


What gives?

Yes, this is just a luck. There is no reason for just big difference, you have only small statistical population to make conclusion.

My math show's that BTC income received is less than one standard deviation from expected.

Can you publish your calculations, please? Because I'm doing some stats on my side, I know pool is performing well (rewards are accurate for number of submitting shares).

There is only one thing which is not calculated into server's CDF - overhead of miners with network latency. I mean, if you have roundtrip to pool 200ms and you are asking for getwork() every 5000ms, you have 4% network overhead. It depends on miner algorithms, but when you have fast miner and he is stopping work when share is found (and is waiting for another getwork), this overhead can be much bigger. For example, Diablo's ISN'T stopping hashing when share is found, which is better.

Those things should be much better with push based protocol, which (I hope) will be ready soon.

Hi, I didn't change anything for many days, I'm currently very busy in my job. There is no reason on server side for this, because other workers are going fine. I didn't block you or anything (and I also write email to user when I see anything bad with their workers).

Any logs from miner available? This looks like network issue & bad exception handling in miner...

I don't think it can help in any case. This is not a Windows.

Slush, did you change something?

No; and other workers looks fine. Which is your new login? I'll check current server logs.

Which miner do you use? Do you have correct password? (Maybe miner just don't show you that you've bad credentials)

Keep calm. I didn't banned you or something, there will be some reasonable explanation.

Maybe I worded it incorrectly. Basically, I am saying that the pool is paying fair share and everything is ok.

Oh, sorry for misunderstanding. Nice to hear that.

Hi there :

I'm running minerd with 792.47 khash/sec
In what average time my Found Blocks and Current shares may change from "0" to another count ?

Gustavo,

I am also running minerd with a similar hash rate.  The amount of shares you will discover and their timing isn't very predictable.  Some rounds you will not find any shares, some you may find two or three.  At least one is pretty normal.  Don't be expecting great things from your mining operation, from three or four days of running my machine I can predict you will probably only generate 0.02 or 0.03 BTC a day.

don't expect your "Found Blocks" to ever change, at current difficulty and with your hash-count it would take an average of ~3years to solve a block, difficulty will rise in those 3years, so you'll have to be very very lucky to win the race, ever.

on the pool, at ~800khash/s, you should find a winning-hash and get a share every ~1.5hours, should add up to about 0.04BTC a day on average.

Hi,

I decided not to report this when I noticed it, because I was concerned somebody would find a way to exploit it, but I imagine it's better to get it fixed:

I used rpcminer-cuda, which reports the hashes it finds.  Within the past few days, one of my miners found the same hash a number of times in a row, and the server accepted it each time.  It seems the server is sometimes assigning duplicate work?

EDIT: This just happened again, but this time the duplicate hashes (including the first) were rejected by the server.  (result: false, error: null).  Is is this an error on my side or on the server's side?
