does anyone know how much bandwidth this consumes? The miner is connecting via RPC to the server several times per minute, isn't it?

Bandwidth is not main concern, but roundtrips/latencies are. I'm working right now on very simple proxy application, which will pre fetch work for few seconds (say 20 sec) to your computer.  Then you will point miner to this local application. It will limit roundtrips (as there will be one request per few second) and latencies (miner will not wait to fresh data).

hi, is there a binary zip file for the cpu miner that doesn't require installation? Thanks

I don't know. Please ask on jgarzik's thread.

[BitLex]

no big deal to use jgarzik's "installer",
it'll just create a new folder of your choice (and shortcuts if you wish) and unpack a few files to it,
nothing to worry about.

I'm just wondering how this is going to affect other users of my shared Internet connection. I suppose those RPC requests are very small?

Yes, very small, approx. 800 bytes per request.

i need a portable file to run on certain computers where i don't have installation privileges

[zipslack]

Alright. Thank you. If it makes one request every two seconds then a rough guess is ~1.4MB per hour. That's tolerable.

Just run the installer on a computer where you do have installation privileges and then copy the entire installed folder to the other computers. In fact that installer will probably run even without privileges if you install to a folder you have access to.

Will you explain the reward parameter?

Threshold makes sense, don't send coins until I have X many.

Reward parameter though has no explanation available on the site. I do see it mentioned in the thread a couple of times but with no direct correlation to the form on the site.

It is explained on homepage - by my extremely poor English  .

Reward is calculated by 50BTC * (your shares) / (total cluster shares) in one mining round (all shares are cleared to zero when block is found).

So when you found 10 shares and cluster solved 1000 shares to find a valid block, your reward for this round will be 50 * 10 / 1000 = 0.5 BTC. Okay?

Currently we are waiting when network confirm first 50 BTC to send first few rewards.

same subject:
is it planned to only send coins >0.01?
so if i have reward:0.01675429 i only get 0.01 and the sub-cents stay where they are?
else i will lose the sub-cents as soon as i send those 0.01 to anyone (if that's the only cent i'v got).

nevermind, that doesnt even make sense, the sub-cents will be lost when splitting those 0.01 to send anyway

[slush]

Sorry, I was talking about that reward on the account page. I never tried to edit it, and of course, it is locked so I cannot. I thought that was a configurable field of some sort.

You are right, I should change it. It really looks like config variable...

The statistics page, could you add current server time to that? It shows when the new generation started, but it does not show how long that period of time has been.
What about also adding a field, that the server has found a total of X blocks? Cool stats to know.

Server is UTC. Better stats (listing already found blocks) are in my TODO. Currently I'm working on performance improvements (proxy etc), because, guys, I did not imagine there will be so large demand few hours after going live :-).

This is good question. Currently sending rewards is in two steps:

a) Directly after block is found, server compute shares and add reward to user account.
b) Script is running every hour (not yet, I will make first payments 'manually'), checking wallet balance and when there is something, send to user's wallets as much as possible.

Originally I tried to send whole reward (third decimal places and more), but today I made small change. Reward is rounded to 0.01 BTC and only this is sending to user's wallet. The rest after rounding remain on user's profile, so no nano-cents are lost.

[BitLex]

ah, i forgot,
it's not the server doing the math/rounding/tell what amount to send, it's your script.
that's great and indeed a workaround lost sub-cents, the server actually doesnt know about sub-cents.

I just got

16/12/2010 20:xx. xxxxxxxx, invalid or stale

what does that mean ?

[m0mchil]

16/12/2010 20:xx. xxxxxxxx, invalid or stale

Exactly what you will get with 'normal' mining - pool server received new, network block just before your last solution. Because pool target is quite low you will see this more often. With ask rate of 5 seconds and network speed of 6 blocks/hour there is probability of 1/120 'shares' to see this.

feature request:
would be nice to have the system stats available on the profile-page too,
auto-refresh is not needed, but it would be nice to just open 1page, not 2, to check how big my share is.

I don't know how the web site is coded, but:

It would be nice to have the stats on every page. Maybe in a header, or on the side?

I already have "reward prediction" in my TODO. I think it is better as it is per-account specific. And it will need some content caching as those stats are quite database demanding.

It is feasible once stats will be in cache (say 10-20 sec). Currently the stats are on demand.

By the way, I need to restart server, because made few changes in application. It will be a second, but we will firstly check exception handling in miners .

[SmokeTooMuch]

I just got this strange error message (attachement).
Any idea what could have caused this ?
Was this because of the restart ?

[BitLex]

guess it's been slush restarting the server,
my miners also stopped and i had to restart them.
