Hi, I have problem with one of my miners recently.
I have two miners on same local network. Everything was ok until few days ago, since when minerd on my laptop cannot connect.

Code:
[deafboy@deafboy-notas ~]$ minerd -a 4way -s 4 -t 2 --url http://api.bitcoin.cz:8332 --userpass deafboy.notas:XXXXXXXXXX
[2011-08-01 12:41:57] HTTP request failed: Empty reply from server
[2011-08-01 12:41:57] json_rpc_call failed, retry after 30 seconds
[2011-08-01 12:41:59] 2 miner threads started, using SHA256 '4way' algorithm.
[2011-08-01 12:42:27] HTTP request failed: Empty reply from server
[2011-08-01 12:42:27] json_rpc_call failed, retry after 30 seconds

The other miner on the same network works fine:

Code:
deafboy@pathfinder:~$ minerd -a 4way -s 5 -t 4 --url http://api.bitcoin.cz:8332 --userpass deafboy.pathfinder:XXXXXXXXXX
[2011-08-01 12:47:26] 4 miner threads started, using SHA256 '4way' algorithm.
[2011-08-01 12:48:44] thread 0: 16777216 hashes, 204.66 khash/sec
[2011-08-01 12:48:46] thread 1: 16777216 hashes, 203.28 khash/sec
[2011-08-01 12:48:47] thread 2: 16777216 hashes, 202.53 khash/sec
[2011-08-01 12:48:48] thread 3: 16777216 hashes, 201.74 khash/sec


I have also another two miners, each one in diferent datacenter working without problems.
I can't see any reasonable explanation.

And btw. I know that CPU mining on laptop is unprofitable I just can't wait for my 5970's Wink

I'm still having the problem that my payout seems about 14% lower than expected.
Part of it is stale shares (about 1.6%).
Then maybe some commission.
But after that, i can't find any reason.

I'm mining @351MH/s and it's very consistent, no network drops or similar.
The graph on bitcoin7 shows this consistency, but it settles around 0.18BC .
The bitcoin calculatoirs predicts 0.21BC at current difficulty (1690906).

So, where does this difference come from and how do i get it back?

I have already contacted slush, bu he has no real answer besides that it's random chance.
It's not, the payout has been stable over a period of a week, the averaging graph of payout is pretty horizontal, which means it's stable and averaged.

So, again, if anyone has an explanation...  Cry

Slushes pool had bad luck, steady for most of the last week.  His response to you was accurate:  random chance.  No pool, regardless of size is immune to luck.

Hi there  Grin

Uhmm I noticed that your pool has been added to this bithopper programm...
It says in the config file that this pool uses a broken scoring algorithm :/

Should we worry about that? One main reason I am mining here is, that
I was thinking the score based system would protect somewhat from the pool hoppers.
On the other hand the pool is pretty big, so the effect they have on the
rest of the pool is probably very small. Still worries me a bit.

We are only hopping for the fun of it on slush, our way to *cough pay back some btc *cough* to the pools. Wink

No, 5 hour block isn't normal. But it seems to be just a bad luck.
And score 5900 is ok, it is being normalized every hour.

Hello, difficulty!

But a difficulty raise is just about 13% - I think it isn't a reason for a 6 hour block.

Actually 6 hour block is still in "sane" range, with current difficulty and hashrate. It is still about probability - as far as I can tell, there's no technical problem in the pool.

slush i think deepbit is screening the blocks somehow

probably a bailout threshold like hoppers use

can we implement this pronto

check it

we don't need this. our scoring method is designed specifically to be hopper-immune

I don't he's talking about dealing with hoppers but rather he thinks deepbit is using some kind of method to screen blocks so they find blocks faster like abandoning a block once it takes longer than x% shares to solve the way hoppers abandon pools after 41%

I don't think something like that would work because if I'm not wrong, a new block depends on the Merkle root so you can't skip ahead. However, maybe it's possible to choose a different set of transactions and attempt to do a new block with them instead. Maybe slippyrocks would like to explain his theory.

You cant bail on a block, if a block isnt found then everyone mining is still mining for that block.

Each block isnt assigned some arbitrary share value on the network, that is a pool feature to split work up and pay users their share, nothing more.

They have an average of 21 min per block last 24 hours. What is our avg in slush ? My feeling is that it may be hours but didnt make the numbers.

BTW, they "only" have about 2x our hashrate. Too much bad luck here and good luck there ?

heh. in fact a block is abadoned at least once per second, when nTime changes. Add to that extraNonce and block is changing hundred of times per second.
