It was tagged as BIP101. XTnodes.com takes about an hour before it scans new blocks for their version number. |

Wooooohoooooooo got my first p2pool payment today
You're welcome. (Toomim Bros found another block. BitcoinXT/BIP101, as usual.) |
|
|
|
ok so run a fresh instance of p2pool and output the details? do you want the output of bitcoind aswell
Just p2pool. Bitcoind is working fine, though GetBlockTemplate is taking up to 1.5 seconds (a bit long). |
|
|
|
2 MORE BLOCKS!!  Both mined on our node, and both mined with BIP101 votes. |
|
|
|
jtoomim - what's the standard queue setting on them?
8192, like all other Bitmain gear. The main problem is that Bitmain's cgminer will abandon stale shares by default, which is problematic with p2pool. (A stale share means a DOA/orphan on the share chain, but could still find a block.) |

Any ideas why I can access my public node via the browser but cgminer can't resolve it up address is 62.75.188.90:9332

On the other hand, your server is responding to http requests. So, uh... something in your node is broken. Maybe check the console output when you try to run it, and post the output (if the problem isn't obvious)? |

You have already got S7? My piece is paid but did not arrive yet...
We have 10 so far, but only 1 belongs to us. |
|
|
|
Is anyone here using the S7 on p2pool? If so, how are they performing? I'm interested to know if they are still using the crazy queue settings with their cgminer fork & if anyone has replaced it with the mainline cgminer yet. If bitmain lower their prices again soon, I might be tempted.....if they work OK with p2pool that is.
Performance suffers with default cgminer on p2pool. I was getting about 4.4 TH/s on p2pool and 4.6 TH/s on Eligius. |

That indicates 7667 seconds used by the poll() function inside twisted, of about 9606 seconds total for the whole program.
I take it you mean milliseconds? Most of what you say goes straight over my head I'm afraid - far beyond my pay grade  Have you tried contacting forrestv at all? No, seconds. That's the cumulative use of all of the 1828987 calls to poll(), or an average of 0.004 seconds per call. On second thought, those poll() calls might be including time that the CPU isn't actually busy, and yielding to other threads and processes. I'll have to take a closer look, and maybe compare the results with my other node (which has much higher loading). |

I noticed on the p2pool scroll every time I hit the the stat page, I get the following errors:
...
2015-09-26 06:34:32.559000 >
2015-09-26 06:34:32.559000 > File "p2pool\web.pyc", line 338, in <lambda>

2015-09-26 06:34:32.559000 > exceptions.TypeError: %x format: a number is requir
ed, not NoneType
Here's line 338 of web.py: new_root.putChild('best_share_hash', WebInterface(lambda: '%064x' % node.best_share_var.value)) I think what it's saying is that you don't have any shares yet, so you don't have a best_share_var. You should know that Antminer S5s have some significant problems with p2pool that causes (a) lost hashrate unless you replace the default cgminer binary, and (b) instability, which can result in (c) hardware damage due to the S5 shutting down the fan immediately when cgminer stops running but heat continuing to be generated by the ASICs for several minutes afterward. |

I've never seen cpu usage go higher than a 35% spike running p2pool, it usually sits around 8% - & that's merge mining 12 other alts. Maybe using XT is the problem?  What OS are you using for your nodes? I think the biggest performance improvement could be achieved by using C instead of python, but this has been discussed many times previously in this thread to no avail. I never could get pypy to work with p2pool, could you describe how you installed/ran it - I'd like to have another go Keep in mind that I have 350 TH/s on my node 24/7, and spikes up to 3.0 PH/s. We probably have about two hundred miners (i.e. computers, not owners) that use our node. I think that might have something to do with the CPU load. Linux prime 3.2.0-4-amd64 #1 SMP Debian 3.2.63-2+deb7u2 x86_64 GNU/Linux Intel(R) Core(TM) i3-2120 CPU @ 3.30GHz I think the problem might be related to the use of the poll()-based reactor in twisted. The poll() function checks a bunch of file descriptors (e.g. network ports) to see if any have data available. When you have a lot of http://pipeit.blogspot.com/2011/07/select-poll-and-epoll-twisted-story.htmlHere are the first few lines of my cProfile stats results for my non-XT node (slower CPU), sorted by the total time each function took (not including subroutines): >>> p.print_stats()

That indicates 7667 seconds used by the poll() function inside twisted, of about 9606 seconds total for the whole program. I think I might try a try:
from twisted.internet import epollreactor
epollreactor.install()
except:
print "twisted.internet.epollreactor could not be loaded. "
print "Falling back to pollreactor. Performance may suffer."
from twisted.internet import reactor
or something like that. It will probably take a little more than that, as I don't know if the APIs are compatible. The biggest performance improvements are usually algorithmic, not language-based. You shouldn't change languages until you are pretty sure that you have the algorithm down. There are some big algorithmic improvements still to be had in p2pool, so I don't think the time is yet ripe for a rewrite in C. (However, there are quite a few modules (mostly in the utils directory, like utils/math.py and utils/pack.py) that would make for straightforward C modules that could be called by python. But more on that later, maybe.) edit: changed the code above. It seems to be working now. I don't know if the performance is improved yet. I'll check back in a few hours. This epollreactor thing will only run on Linux >= 2.6, by the way. |

Nice to see some blocks rolling in again - makes up for the baron spell earlier. I'm seeing some big spikes in hash rate lately, up to 5Ph+ - hopefully a big player will be joining us soon  Both of the two p2pool blocks found yesterday were mined at our node. We've been getting a few people renting hashrate and pointing it at our node or a couple of other nodes that run on BitcoinXT. Yesterday, we had someone point about 2.5 PH/s at our node for a few hours. That miner found one of the blocks. http://xtnodes.com/bip101_mining_pools.phphttp://74.82.233.205:9334/static/graphs.html?WeekSpeaking of > 2 PH/s on a single node, is anybody working on (or interested in collaborating on) performance enhancements for p2pool? I'm seeing a lot of load spikes up to 100% CPU cure utilization for up to a few seconds by the p2pool process, and switching to pypy doesn't solve the issue. Right now I'm using python -m cProfile -o cprofile-001.log run_p2pool.py to collect and analyze data on what functions in p2pool are hosing my CPU. |

I have the same question, it will be shipped from Israel or other country?
I think my NDA is expired now. Right, Guy? They will be shipped in two separate shipments. One by ocean, one by air. The ocean shipment will include the chassis, controller, and the PSUs. The air freight will include the hashboards and heatsinks. I believe that both will originate in Israel, but I don't have hard evidence on that. |

Toomim Bros may be arranging something with our group buy where we take single SP50s and split them up into shares by using cgminer load balancing between pools. Still waiting to hear back from Spondoolies about pricing and MOQ and whatnot. They'll be asleep for another 10 hours, but I might get a response tonight. Please send an email to orders@toom.im if you're interested. Edit: This will not be happening any time soon. |

It is spring here and Australia and the temperature gets over 45c here in summer so I will be looking at adapting my S7's to the Syscooling S5 cooling kit
You could also use evaporative coolers (swamp coolers). Those work quite well in dry climates. Here in Washington state, the highest outdoor temperature we saw this summer was 43°C, and with our evaporative coolers and zero A/C, our indoor temperature never got above 30°C. Typical intake temps for us are below 26°C unless it's above 38°C outside. That said, Antminer gear is usually designed to run fine in high temperature environments. 45°C is definitely above the recommended operating temperature, but I've seen Antminers run okay at that temperature with no reductions in hashrate. Of course, if you have temperatures that high or higher plus positively pressurized hot aisles, then you might have a problem... |

Wow, $220 for a PSU? Host with us and we can get you a PSU for $80. Our PSUs are voltage adjustable from about 11.8V to 12.8V to allow for either improved overclocking capability or improved performance. |
