[4+ EH] Slush Pool (slushpool.com); Overt AsicBoost; World First Mining Pool

All this crap to try and prevent "fraud".  Delaying/removing stats doesn't stop that BTW.

Tell me the reason why not. (well, I know it, but I bet you don't.)

The server already only accepts shares for current blocks, but what you've done is overkill, plain and simple.

No server accept shares for whole round, not only for current block.

I've updated my miner to reduce share loss in pool situations. Update to newest.

Thank you.

So it's been changed back to how it was. The server accepts shares for the current round, even if the block count changed by 1?
Any old work from previous rounds are ignored?

[slush]

No, nothing changed. It is how it works all the time. You mixed it with jgarzik's pool, which worked like you're talking.

I really enjoyed seeing some of my customers on the top.

Maybe us GPU miners should make a hall of fame, too? My miners found a total of 1184 blocks and I guess ArtForz's found even more; not to mention all those CPU miners running a year ago.

Why everything changed?
I mean before it will show how many shares i mined ...
Now many things not showing.

Read this forum for few posts back. It will be back soon.

Btw. the pool need only 3 shares to found block 106959 yesterday. Congratulation for all three users, which get 16.6 BTC for one share! :-)

But the round took 7 seconds to complete and the pool should have made 52 shares at this time frame. Poor those who earned a stale share at that time. How many stale shares did you log during this round (and on average during all rounds)?

Stale shares are around 1-2%. Of course there were many stale shares in this round, but it is how it works. Calculating stale shares is not fair, because people get reward for something which cannot give valid block to pool. It also improved overall pool performance, because some people had strange miner settings (ask rate over 180 seconds etc).

So 7 seconds for three shares at the beginning of round seems to be fine.

I'm not advocating counting stale shares but I was curious how many stale shares arrived within the same timeframe. It can show the delay inefficiencies.

I would expect more. With 5s getwork refresh time, most of the workers should have worked on the non-stale block at least some of their time. Some of the workers should have worked most of this time. Only 3 shares is below 0.5s of the pool capacity. I would expect 10-20 shares.

[slush]

Only 3 shares is below 0.5s of the pool capacity.

It is below _average_ pool capacity. When new block arrive, there are many seconds with significant lower (effective) hashrate. There is also significant variance in share submitting rate. Sometimes there are almost 20 shares per second, sometimes there is almost nothing. And I don't see any trouble with stale block algorithm itself.

That's random for you
I'm having some connection problems, quite regularly a connection is lost every 7-10 minutes, is it just me?

If you see connection timeouts, I'm solving this. looks like network is shaped. I'll try to upgrade my server today. If it does not help, I'll contact server support for some help.

In case you need it, check midphase.com server plans.
Nice network, price and support.
I have servers with 2 yrs uptime with them.

After discussing it with server support and little fiddling with server, I think it should be better now. Can you confirm that?

Thanks gusti for the tip. I have few boxes on Linode and I love the service and their support, so I'd like to stay here. I also think we've fixed the network issue, so no need to migration right now. Keep in mind that those 160 requests/s (10.000.000.000 requests per month!) are pretty high traffic and everything must be perfect to run smoothly on VPS.

Hypothetically speaking, if I made available 25, modern dual processor, quad core, servers for 2 hours per day, roughly how many, on average,  bitcoins could be expected from joining this pool?

Almost same as on standalone mining, only with steady payouts. Check http://www.alloscomp.com/bitcoin/calculator.php and divide 50BTC / (days from calculator) to get your expected daily reward from pool mining.

[slush]

I did small pool update today. Now you can see 'total score in round' and scores for every worker. For now this does not affect calculating rewards and I'll introduce meaning of those numbers tomorrow.

I'm also pretty sure that today's server fix will also have positive impact to daily rewards, because it improved server performance for some percent. So stay tuned :-).
