"Expected per block" on website corrected to take the reward halving into account.

I also added MPoolMonitor under "tools" -> "third party apps" on the website.


Hi Doc,

When can we expect vardiff and stratum support on the main pool?

Thanks,
gigavps

I have some little things still to do on Stratum support. I hope to enable Stratum on the testport within a couple days.

If everything runs perfectly I could perhaps enable Stratum and GBT with var diff on the main pool before the weekend is over. But perhaps delay var diff on getwork a bit longer until hashpower.com supports it.

Also I think ztexminer doesn't support var diff. And perhaps never will?

My only other concern with vardiff is that when you enabled it on the main pool, it was done per worker.

Does vardiff now work by used the x-mining-hashrate header if available?

GBT replaced X-Mining-Hashrate with the "target" request option (BIP 23 Basic Pool Extensions). Stratum has no equivalent (and no HTTP for headers) yet.

It uses x-mining-hashrate only for the initial difficulty. After it has measured the worker's hashrate it uses that as a basis for difficulty. Using only x-mining-hashrate basically means letting the user select the difficulty - I'm not sure that's a good idea.

I have a pool-wide setting for max difficulty though. I can set this to what is appropriate for 1 minirig now, and later adjust up to what is appropriate for 1 SC minirig. So 10 minirigs running on the same worker account will get the same difficulty as 1 minirig.

Is that then still an issue?

GBT replaced X-Mining-Hashrate with the "target" request option (BIP 23 Basic Pool Extensions). Stratum has no equivalent (and no HTTP for headers) yet.

I didn't implement the target request option yet. I don't know if I would use it for anything but the first minute either. Letting a user with 10+ TH/s set the difficulty makes me a bit uneasy. Tongue

A max diff of around 20 would be nice. Smiley

Well, you could always set it up to honour it within some reasonable limits (or maybe leave it unbound upward, so miners can always opt to increase their variance at will). Admittedly, I also haven't seen a need to implement "target" requests yet either.

lol no HTTP - GBT uses HTTP coz (as you said) it was too hard for you to do such an enhancement Tongue

Adding an 'options' to Stratum is a minor thing - pity you can't even take the step past HTTP to see that's all it is.

All three of my miners on cgminer are complaining that bitminter isn't providing work fast enough.  Stratum is coming soon, right? Smiley

"Isn't providing work fast enough" (even with BFGMiner) is most likely a problem with your miner, not the protocol. Con intentionally designed GBT support in cgminer to work inefficiently, but as a side-effect of this particular inefficiency, there is no excuse it should ever be starving for more work.

This isn't GBT, this is a LP.  And I don't recall seeing the message anywhere else.  It is starving and is sending work to backup pools.

As usual - you don't even know what you are talking about.

So ... do we assume you are just stupid enough to make that comment?

... or lying to try and attack cgminer in a way that is completely false?

Well, why aren't you using GBT? Then you'd definitely have work ready to go as soon as the LP comes in (GBT uses LP too).

The "not providing work fast enough" message comes pretty quickly after long poll - may not be a big deal.

Yes, we have GBT testing on port 9000 now and Stratum testing will begin soon.

If I put GBT on main port now then users with cgminer with GBT support but earlier version than 2.9.4 will get 100% rejects. I need to add a workaround for this bug before enabling GBT on the main port, otherwise it could be pretty painful for some users.

I hope to move GBT and Stratum to main port within a week's time, if not before. Maybe before the weekend is over, if testing goes well.

Why not keep them on separate ports :3333 for stratum seems to be the default port chosen by pools using it.

Yeah, it will be GBT and getwork on the regular port and Stratum on a different one. But the GBT/getwork responses will have an HTTP header informing the miner where to find the Stratum port.

Now that I know GBT is on 9000, I'll point my miners there.  I don't recall seeing that on the website, and I certainly didn't wade through the 100 pages of data here.

EDIT: it seems stats don't report work if you use the GBT port. Sad

Ah, that makes sense. The solution I've used in the past with older bugger miner versions is the check the User-Agent. Wink

BFGMiner interprets the Stratum header as "prefer Stratum over the current protocol", so IMO it would be better if it were only offered to getwork requests.

Yeah, it's only for testing. GBT will soon be on the regular port. Port 9000 may be unstable, and hashrate on that port won't show on the website. But you do get paid, and the hashrate will show in shifts, it just won't show as current hashrate.

It's a bit of a hack. In the future I will add proper support for multiple servers and they will show properly in the stats.

BFGMiner interprets the Stratum header as "prefer Stratum over the current protocol", so IMO it would be better if it were only offered to getwork requests.

Good to know, I'll just add the header on getwork responses then.
