Typo. It should be mining.bitcoin.cz. Czech Republic, not New Zealand.

How are the rewards calculated?

It shows my reward is 0.00237 BTC

But if i calculate my share it should be about 1.8 BTC, thats quite a difference...
I'm calculating this with (myshare/totalshare)*50 (as according to the website)

This is on my fast pc 60.000khash that has been running double the time compared to my slow pc.

My slow pc with 20.000khash has a 0.63 BTC reward, which is correct according to the same calculations...

Am i missing something?

[doublec]

The instructions say to use one registered miner for each remote miner instance connected. Does this mean multithreaded miners need to be limited to 1 thread only? Will running them with multiple threads confuse the share algorithm?

[BitLex]

I don't really understand how to connect the miner to the pool. I'm using poclbm but I always get

C:\Bitcoin\poclbm_py2exe>poclbm.exe -o mining.bitcoin.nz --port=8332 -u Elanthius.wk033 --pass=pass -d 0
Unable to communicate with bitcoin RPC

Any suggestions?

try using mining.bitcoin.cz, that might work.

your 0.00237 BTC reward is leftover from the last round,
the reward for the current round will be calculated and added to your reward as soon as a new block is found,
so about 1.8 BTC is what you can expect, not what you already have.

correct me if i'm wrong.

[kwukduck]

I started my old pc a lot later then the fast one, but the slow one already has the full reward, so it seems a block was found in the meantime...

Hey, going to throw in my Radeon 5970 for fun wait a couple of hours and you'll be over 2Gh/S

[doublec]

What's the current difficulty value for miners to get a share?

Found it, '32' according if it's the listed difficulty under each registered miner. So that's about 19 hours for a share using a 2,000 khash/s machine (my estimate of an average dual core laptop).

[davout]

did someone manage to connect jgarzik cpu miner windows build to the pool ?
getting work decode failed when i try :/

no, there's no need to limit multithread miners to 1thread,
i just tested jgarzik's miner with 2threads and it runs fine/gets me shares.

Found it, '32' according if it's the listed difficulty under each registered miner. So that's about 19 hours for a share using a 2,000 khash/s machine (my estimate of an average dual core laptop).

and again, i just had 2 of 3cores @ 2400khash/s each running for about 15minutes and got 2shares/found 2 winning hashes.
that's not even close to your 19hrs.

yes, that's the one i use for testing CPUs on windows.

Yes, I guess the difficulty calculator I used must be incorrect. Any idea what the estimate would be?

[davout]

yes, that's the one i use for testing CPUs on windows.

Which version ? Did you build it yourself ?

[doublec]

I got the error you got when I had the wrong username/password.

[slush]

Oh, too much traffic here 

What's the current difficulty value for miners to get a share?

32 is not difficulty, it means that target have 32 bits of zeros. You cannot compare this difficulty to global difficulty. 32 bits of zeros leads to ~1-2 blocks at 1000khash/s.

It shows my reward is 0.00237 BTC

This is the rounding rest, reward from previous round was already sent to you. Reward for current block is calculated when block is found.

The instructions say to use one registered miner for each remote miner instance connected. Does this mean multithreaded miners need to be limited to 1 thread only? Will running them with multiple threads confuse the share algorithm?

1 instance == 1 piece of software, NOT computer, NOT CPU/GPU core. Everytime you run miner software, each of them must have different credentials, otherwise your shares will not be correct.

Thanks, it is second 5970 in pool :-)

did someone manage to connect jgarzik cpu miner windows build to the pool?

Yes, it is working. No special settings for Windows. You probably have bad URL, connection or whatewer.

[BitLex]

Which version ? Did you build it yourself ?

0.2.1 and no, i only use pre-compiled binaries.

[doublec]

32 is not difficulty,

It might be a good idea not to call it 'difficulty' on the webpage...

[kwukduck]

Thanks for the answer slush, indeed i received them now

[Essjay]

32 is not difficulty, it means that target have 32 bits of zeros. You cannot compare this difficulty to global difficulty. 32 bits of zeros leads to ~1-2 blocks at 1000khash/s.

I suspect that 32 bits of zeroes = a difficulty of 1? (i.e. the original and easiest difficulty?)

Exactly!

hey slush,

do you feel like opening the source of your web interface ?
could give you a hand with impementing some stuff and polishing it

it's Rails isn't it ?

No, it is Django.

About opening source: I like coding it and currently do not need a help, thanks. I wish to open critical app parts for 'security review' soon, but I probably do not open source it fully. It is a service, as mybitcoin or mtgox is.
Pool is strongest when there is plenty of mhash/s, so I have no motivation in creating another pools.
