Cool thanks guys.

Is 1.7% DOA a reasonable number?  wondering if I should take step to improve it or just keep it as is.

Just wanted to chime back in on the Cointerra discussion, I've been a bit busy since yesterday.

I can confirm in my tests that the Cointerras do indeed hash at about a 20% loss on p2pool.  I switched my miners back over to BTCGuild to test it, and bingo, I went from 1.2-1.3 TH/s on p2pool to the full 1.6TH/s on BTCGuild.  So, right now the Cointerras have been left back on BTCGuild to mine there.

I can also confirm that fiddling with the difficulty and pseudo-share settings as I did made no improvement, and in some cases actually degraded performance.  I tried ranges from /512 through /2048 with combinations of +512 through +2048 as well.

FYI, I'm not going to do any more testing as I've just put the Cointerras up for sale.  Going to stick with my S1/S3's since they are running beautifully and I want to stick with P2Pool.

OK so I have given up using my Terraminer IV for p2pool ... it's just 20% less effective due to unknown reason.

I have pointed my Antminer S3s to my node, no problem, hashing good... Perhaps I will just stick with S3 with p2pool, and Cointerra with traditional pools.


Now I wish to setup merge mining.  Can someone please point me to any guide for Namecoin merge mining setup for Windows 7???  Thanks.
Sorry to hear that your Terraminer doesn't work with p2pool and suffers the same kind of performance degradation as the S2 does.  I know it's a long shot, but you might want to open a support ticket with them (I KNOW it's a long shot... lol).

Setting up merged-mining is pretty easy.  First, download and install the wallet (or you can use the *coind) of a supported coin (NMC, IXC, I0C, DVC, HUC, FSC... any I missed?) and get it all synced up.  Second, edit your coin's configuration file.  For example, here's my NMC one (changed the user and password):
Code:
server=1
daemon=1
listen=1
rpcuser=SOMEUSER
rpcpassword=SOMEPASSWORD
rpcport=7333
rpcallowip=10.0.1.*
Please use different values for user and password - these are just examples.  Also, for the rpcallowip, use a range that makes sense for you.  My local network is 10.0.1.*.  Yours might be 192.168.1.*.  Of course, you could always just put in * if you don't want to restrict it.

Now, when you fire up your p2pool node you just add the values.  Here's the snippet from my startup showing NMC:
Code:
./run_p2pool.py --merged http://SOMEUSER:[email protected]:7333 ...
10.0.1.14 is the IP address of the machine where you put the NMC wallet.

That's it... you're merge mining BTC and NMC.

Looks like 3 blocks on the 19th so far?? my Node is only showing the first one.
What would cause it to not show me the last 2 blocks?
I am on line, and hashing away, I have active connections?

Thanks for any answers.....

Stale p2pool shares that meet bitcoin difficulty are still submitted and will not show up in p2pool's standard interface.

You can see all p2pool found blocks here: http://minefast.coincadence.com/p2pool-stats.php


Thanks as always, I kinda knew that but just thought it was more of an issue with me and not everyone like that.....
Thanks. You always start thinking that your own node is screwing up.........

Thanks JB, so it's not just me then. I'll investigate further........

Edit: I notice forrestv made a change to the p2poool repo ( Shocked!) 7 days ago, increased maximum worker difficulty 1000x, that wouldn't be the cause......would it?

Edit2: Tried running namecoin on rav3n_pl fork with the same results, so it's not a p2pool issue. Had to close the namecoin wallet as it was eating cpu as well. Oh well, that'll have to stay off then.......... Tongue Very strange.
There have been some huge blocks recently aggregating a mass of tiny inputs. This seems to lead to getauxblock taking a very long time. We are looking into it but it might take a while.

BTW: As far as I know Namecoin mining reward variance is very high with P2P. We would be happy to support any plans to improve this, maybe with a bounty.

The reason the variance is so high is because each node that is merge-mining is effectively trying to solo mine the blocks for the coins (NMC, DVC, etc).

It would be nice if the entire hashing power of the pool, or at least the hashing power of the nodes that are merge-mining, could be applied rather than individual nodes attempting to solve the blocks.

Thanks for that phelix - I thought I was going a little mad there. I'm still not sure how large block size can cause a timeout error like this though, tbh - what am I missing?  Tongue

Peace.

EDIT: Scrap that - I get it now. (I was too lazy to read up on it before  Wink)

I saw this on wiki:

Requirement:
    Windows:
        Install Python 2.7: http://www.python.org/getit/
        Install Twisted: http://twistedmatrix.com/trac/wiki/Downloads
        Install Zope.Interface: http://pypi.python.org/pypi/zope.interface/3.8.0
            Unzip the files into C:\Python27\Lib\site-packages

Well I have not installed the Python 2.7, Twisted and Zope.  Will that be a problem resulting in my Cointerra's under performance???

No.  If p2pool is running, you have the right requirements OR you're using the executable which doesn't need that.

I'm not using my S2 on p2pool because of underperformance.  I tried for a few days throwing away 10% of my hash power and 5% rejects, and it was abysmal.

Read... So, it would seems to me that a 10~20% decrease in efficiency for large miners such as Cointerra and S2 is a known issue and unresolved .....  Cry

Not sure if I should stay in P2Pool with my Cointerra gears in this case .... sad  Cry

While the issue with the S2 has been well documented here, you are the first case of a problem with Cointerra gear I have seen.

Cointerra is specifically listed in the wiki as working well.

https://en.bitcoin.it/wiki/P2Pool#Interoperability_table

I would also like to hear from other Cointerra miners on p2pool.


i have setup my own node on Windows 7, and mining for over a day.

hash show up on cointerra is a constant 1350 GHs instead of the normal 1600 GHs... checked not heat problem, can resume 1600 with regular pools......

desperate to find a solution.

Results might have to wait, I think I might have an overheating controller on my first unit.  The CTA0 board temps keep going through the roof, then bouncing to almost nothing, a sign that the machine is effectively throttling itself from burning up.  I'm going to go replace the thermal grease and see what happens.

Initial comparisons on the other controller so far have been about equal to the other, non-modified Cointerra, about 600GH/s.

so as it seems, each half Cointerra having 680GHs when mining at p2pool instead of 800GHs is normal??? I wonder if it is just the p2pool share system makes the cointerra machine makes it think it is mining slower, but it is actually mining at 800GHs maybe???

I believe the S2s have a problem restarting work every 30 seconds, and that's why the hashrate decreases.  I'd imagine the same thing happens with other ASICs.

Is there a workaround for this problem?  P2Pool is so supper cool, but having 20% ripped off the mining speed is not cool.
