I have a question.
My 6770 getting about 180MH/s so I decided to try lottery (solo mining) aside of p2pool.
I run cgminer this way:
cgminer-2.3.6-win32\cgminer.exe --rotate 5  --no-adl -I 3 -u user -p pass -o http://127.0.0.1:8332 -u rav3n -p nn -o http://127.0.0.1:9332
8332 is a bitcoin (solo)
9332 is a p2pool

It looks to me, that when it is switched to 8332 it is still getting new longpool works from 9332 but not longpool resets - producing rejects one after another (ST is rising all the time when connected to 8332).
IMO it should NOT getting nothing from 9332 LP or get all longpool commands form it.

Code:

I have run something wrong or better to run 2 miners one for solo and second for pool?

A few remarks:

- Solo mining using bitcoin is not optimal: bitcoind does NOT support longpoll.  So doing solo mining directly on the bitcoin daemon is less optimal as you will do some work on old work

- Afaik cgminer tries to be smart and use all pools to see when a new block is present, and use that to trigger new getwork from other pools.  In other words, this is an advantage as it will compensate the missing LP from the bitcoin client

- 180 MH/s is not enough to do solo mining.  You're better of mining in a pool.  Your variance will be too high.

- You should consider p2pool as solo mining: higer profits with higher variance.  I would only use a real pool if I'd only have 180MH/s, as p2pool has a higher difficulty.

I`m getting about 0.015 BTC per block... it is 10x more than i get from slush pool. But still to make 50BTC i need 9 YEARS of pooled mining. Thats why i want to try solo aside of pool.

Just FYI, that is the exact opposite reason most people solo mine. You you will likely never see any BTC. And definitely none before the reward halves in December.

Thats why I want to switch between solo and pool.
It is even funniest in 2.3.3
When I switch to solo (or even DISABLE pool in options) it is still getting LP messages and sending shares to pool!
I`m just curious what happen when I found block by accident? It will be send to me (as solo) or to pool?

I agree. You should not solo mine if you want any return in the near future.

To prove this point, let's do the math:
  • The current difficulty is ~1508590.
  • This means that for every share with difficulty of 1, there is a 1/1,508,590 chance of it being a block.
  • For shares with a difficulty of 1 there is a 1/(16^8) or 1/4,294,967,296 of any computed hash being a share.
  • At 180,000,000 hashes/second, on average it will take (4,294,967,296*1,508,590)/180,000,000 seconds (of continuous 24/7 mining) to find a block.
  • That is 35996360 seconds, or ~416 days (1 year + 1 month + 20 days) to find a block. By then the difficulty would have increased drastically, and you will get only 25 bitcoins for your over 1 year of mining because of the reward halving in December.

Do you still want to solo mine? If so, I would look on the CGMiner thread (https://bitcointalk.org/index.php?topic=28402.0) for how to set it up properly. Otherwise I would recommend a pool with merged (Bitcoin+Namecoin) mining where you can set your donation/fee percentage, such as EclipseMC (https://eclipsemc.com/) or Ozcoin (http://ozco.in/). I would not recommend P2Pool for your current setup, because of the increased difficulty for shares (600 vs. 1).

When you run connected to a pool/server that doesn't support longpoll, cgminer will find a longpoll from another server and use that to help it detect block changes (as kinlo said). Also, some work will always go to the backup pools (which is why you still get accepted shares from p2pool while connected to your bitcoind) unless you enable the --failover-option. The  large number of longpolls is perfectly normal on p2pool.

Thanks for info Smiley
My question stays: if I`m connected to bicoind and p2pool is longpooling when I found block where it will be sent? Directly to bicoind and count as mine only or to pool?
I`m currently using cgminer 2.3.3 where I can even DISABLE p2pool from pool menu and it is still working, longpool is sending data and miner is sending shares...

Normally the block will be send to your bitcoind, where your miner get the work, the longpool message from p2pool is just used to get fresh work for your miner from bitcoind.
But not sure it's a good idea, because you will get half the revenue from p2pool and very title chance to find a block in solo,  may be your lucky enough can try !

Yes, I know this is loooooongshoot, but I`m getting 0.01-0.02/block on pool so.... ;]
bitcoind does not accept "shares", only p2pool does. If you're mining in bitcoind, it only accepts block attempts and nothing else. If you're mining on both bitcoind and p2pool, then you'll see shares going to p2pool and pretty much nothing while you're on bitcoind unless you hit the jackpot. The longpolls will keep coming in and that has pretty much nothing to do with bitcoind since they're coming from p2pool, and when a longpoll comes in, some work is sneaking to p2pool in the process. In short, these miniscule amounts you're earning are coming from p2pool. If you found a block, cgminer would also add the words BLOCK! to a share, and you'd earn 50+ BTC.

Primary developer/maintainer for cgminer and ckpool/ckproxy.
Pooled mine at kano.is, solo mine at solo.ckpool.org
