[~1000 GH/sec] BTC Guild - 0% Fee Pool, LP, SSL, Full Precision, and More

[eleuthria]

US West is reachable again (for now).  I did a complete reset on our pfSense load balancer.  Sometime around 3 AM it completely locked up until I woke up at 5:15.  100% CPU usage locks are a pain because it means no logging can even occur to give some pointers at the cause.

It continued locking up roughly every 10 minutes after a reboot.  This, plus the strange long polling related lockups, was reason to reset the VM completely.

This new server is a completely different beast from our others, and the technical problems its having simply can't be recreated in a local environment due to IP based load balancing on tens of thousands of connections.  The load balancer had some issues being setup initially due to a different network environment than my original test server, so perhaps this reset got rid of some poor configurations that were done on my end during the initial setup.

Got some long rounds...how I wish we were back to over 3000 GH/s! We are so close though to getting everything back and better than before.

Even at 1600GH/s this is not normal. Yesterday we have spectacular luck, but since the new server went up there has been terrible luck. Maybe is just coincidence, who knows.

same here , very bad results from yesterday .  i cant mine for so little payout when i know they can earn more

[eleuthria]

you realize you're allowed to sleep, right?

I get a few hours.  During those few hours the servers team up and break on me, that way I have an urgent reason to wake up instead of hit snooze.



Long Polling is back on US West, so the stale rates should fluctuate back down to < 1%.

hi everybody,

I noticed some connection problems to the german server. it started about 3pm local german time (CET +2), so about 4hours ago. are there any issues with that server?

cheers iro

Sorry eleuthria  I have to switch pools for a while (at least until you get this all worked out) My normal payout in 12 hrs is 1.3 BTC and the last 12 hrs I got .65 BTC. This has been happening since you brought the new server online. I understand there can be bad luck, but I'm thinking these really long rounds (so many of them) are a result of miners switching pools when problems are detected thus 2 Thash/s is really not 2 Thash/s. With me donating it just does not make sense to stay and mine until the bugs are worked out. Normally I am one to wait it out, but something feels not right here this time.

Good luck, I hope you are able to get it under control.

Luck in past 24 hours       2222279 shares   (-29.7%)

Doesn't include our current round which will drag it down even more.

For those keeping up with other pools, right now BTC Mine has had a streak pushing them into +90% luck.  Luck is just that, LUCK.  The server issues are _NOT_ affecting our luck, they are affecting our hash rate, which we have less speed being utilized to normalize the effects of luck (although you can NEVER eliminate luck, and +/- 30% is still very possible even at 3-4 TH/sec).

The new server has now been spitting out shares for the past 3 hours without a single idle except for the two seconds it took to re-enable long poling.

I understand what you are saying, but right now I'm sitting at > -50% luck on BTC Guild in 12 hrs, not good at all.

[jjiimm_64]

Yup.  we have had some long rounds......

I am keeping all my 5.5G here.  I pointed all workers to uscentral yesterday.

i only mined .97btc in the last 24 hours with 2.3Ghash. Whats the problem? thats like 50% of what I should be mining.

[sharky112065]

That's what I've been trying to say in my previous couple of posts. Something is definitely not right here. My numbers do not coincide with the sites luck reporting.

[eleuthria]

i only mined .97btc in the last 24 hours with 2.3Ghash. Whats the problem? thats like 50% of what I should be mining.

2.3 GH/s at this difficulty, assuming 0% luck influence  and no idle time = 1.48/24 hours.  Current luck is -30% over 24 hours.  Bad luck + idle time on the servers = lower payouts in the last 24 hours.  NOTHING CAN BE DONE ABOUT 24 HOUR LUCK.  EVERY POOL HAS BAD LUCK STREAKS, EVERY POOL HAS GOOD LUCK STREAKS.


Luck is not the WHOLE issue, but it's the majority of the issue.  Idle time is the other side, and that has been fixed.  US West has been running over 1.2 TH/sec, and has not had a single idle in the last 4 hours since re-installing the load balancer.

Pool luck is down. There is also individual luck. Sometimes I get a higher amount of shares submitted in a round than I should for my Mhash. Sometimes I get lower. If you understand what luck is, then this should not be that surprising from time to time. However, a lot of people do not.  Even after they say they do, I don't think they really get it, because if they did, then they would realize the only reason to move their miners elsewhere is if they are getting connection problems on US West, Central, East, and DE. If the new server is giving you problems, then try another one temporarily. There are always bugs to be worked out and things should eventually stabilize, it is just very difficult to anticipate problems before they occur. Patience is a virtue.

[ellipsis]

I have a couple of scripts that I use to keep my workers on the BTC Guild server with the lowest load (available for all, see my sig), but they poll the JSON endpoint. Unfortunately, it returns a busted result (missing closing curly brace) for the workers if you haven't returned any shares in the current round. Maybe if I'm lucky, that missing brace could be put in there soon. I have a few other API improvement recommendations, as well, if suggestions are welcome.

OK, you convinced me to go back to uswest. I put all my miners back on uswest and now I am getting work queue empty, miner idols and disconnects.

This is getting frustrating as hell. 

[jjiimm_64]

at lease your up and running...  I lost 4 of of 5 rigs to the heat. and I will not be home for 3 hours  down to 1.2G now

Ouch. That sucks. Summer is a bitch man.

[eleuthria]

Just concluded a stress test on US West (pointed all DNS entries to it for about 45 minutes).  1.8 TH/sec and no idles reported in the chat room during the test.  We did find that occasionally a long poll would be met with multiple stales (sometimes as many as 5 or 6), so I'm looking into that before merging any servers into it.

[russelljohnson]

I'm getting about 1.5% stale shares. Why is it so high? For comparison, Deepbit gives me about 0.4% stales

Try east or central. They probably have better latency and such than slush which is euro and not LP.

[WesleyK]

Im getting like 6-7% stales on us west. Nothing changed on my side and i was having <1% stale shares before. Something wrong?
