Can someone please explain to me the benefits of choosing a different difficulty for your miners D1, D2, D4 etc. I am running BFL Singles will this allow me to get more shares in? Also is BFGMiner compatible with this function?

Less share traffic and less stales with higher difficulty shares.
Don't know much about BFGMiner, but cgminer works perfectly for me with Singles and Icarus boards at D16 and D32.

Diff32 shares support disabled temporarily. It will be back soon.

x32 shares are supported now.

Hi Balthazar,

I have problems with Ztex BTCMiner and Diff > 1 Shares on your pool. Sometimes I get "target-miss" rejects although I think the result does meet a difficulty 2. Here are two examples (n=nonce, t=target, h=hash):

Share 1 is OK:

Why do you reject the second one? As I understand it, 0x1f is lower than 0x80 and therefore the hash should be a valid Diff2 share. Or do I understand something wrong with the target?

With BTCGuild (Stratum) I don't have such issues.

Thanks

[Balthazar]

Thanks for report, I'll try to investigate this today.

I found and fixed this bug.

I wrote simple test program using my target-testing function:

Code:

$ ./difftest
i: 27, 18 < 80
t: 0000000000000000000000000000000000000000000000000000008000000000, h: 9d25026dc55bce5a2fcc67bbbf25f3fffbddf3899049d7bdb16b151800000000, r: 0

$ ./difftest
i: 27, 40 < 80

So, target testing working correctly.

But now look at my last post. Some of them are treated as invalid with a target-miss error.

I'm sending valid diff2 shares back to your pool, but they were rejected with a "target-miss" error.

[Balthazar]

according to your prog, all mentioned shares are valid diff2 shares

Yes, I know. I mean, that I'm using identical function for shares checking on pool. In fact, hash_greater_target function was just copied&pasted from pool daemon source code.

Could you provide this shares for debugging? Thanks.

[Balthazar]

Now "target-miss" info logging is enabled on 8080 port, for debugging purposes. If you wish to continue, you can try mine on 8080 port with diff > 1. I'll analyze logs as soon as possible.

[gigica viteazu`]

i set my workers on D32 and i get a lot of Share below target in CGMiner, is that ok?

[Balthazar]

If you switched difficulty when miner is running, you can get some invalid shares with "target-miss" reason. It's normally because miner performs update of work cache not in real time.

P.S. "target-miss" shares are not below target, actually.

[gigica viteazu`]

actually, i closed all miners, made the switch on the site and started miners again.

oh... and i get this all the time

Code:

[2012-10-30 22:54:36] 4 gpu miner threads started
[2012-10-30 22:54:36] Pool 0 not providing work fast enough
[2012-10-30 22:54:36] Share below target

[Balthazar]

Oops, i didn't understand you right. Yes, it's normal for shares with D > 1.

Hi,

I'm mining right now with diff2 on port 8080. At the moment I have 396 getworks, 45 accepted shares and 48 rejected shares. I will stop now. The reject reason is still target-miss.

So long...

[Balthazar]

See previous message.   1/2 of received shares are actually diff1, not diff2. Something wrong with miner. :-(

[gr0bi42]

See previous message. 

OK, these hashes are not valid diff2 shares. I will check the logs, maybe I'll find something.


But it's still buggy from my side. Look at this example":

A valid diff2 nonce n=347380e0 gets a target-miss (json-id 75). The corresponding getwork json-id: 73. What could be wrong on my side???

[Balthazar]

I don't know. I can't see "target-miss" rejects from another user's, almost all of that generated by your worker. So I need some time.

I'll continue working on it few hours later.

[gr0bi42]

See previous message.   1/2 of received shares are actually diff1, not diff2. Something wrong with miner. :-(

Hmm, maybe it's the miner, but I cannot see why. Look at this example:

I got a "target-miss" error for json-id 115, which is nonce=430fdafa, block with json-id 112 and a valid diff2 hash=f1f38404e253aef6fa1609b1d96474d8a731ff5dda808a7cdd6b184000000000.

At least this share should not lead to a target-miss error.


I will further debug the miner, maybe I will find something...

[gr0bi42]

I don't know. I can't see "target-miss" rejects from another user's, almost all of that generated by your worker. So I need some time.

I'll continue working on it few hours later.

OK.

Some further info for you. I'ed modified BTCMiner, so that only 1 FPGA is running. It starts immediately mining on your pool with the diff2 worker. Miner submitted 2 shares, one valid and one rejected (target-miss). "Request: [...]" is the direct input for the HTTPConnection and "Response: [...]" the output. Nothing between.
