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

[rasputin]

More changes to pushpool this morning after sleeping on the problem.  Starting to research EU and east coast VPS and dedicated hosting providers to start setting up 1 or 2 new servers to load balance with the current one.

Could you provide some load statistics for those of us interested in that kind of data? In/outgoing bandwith, # of db queries, web page requests and whatnot per second, for instance.

Have you done any profiling to figure out where the bottlenecks are?

An order has been placed for a server in the EU.  It will probably be ready to go live on Thursday.  The DNS will load balance between the two, but I will post special URLs that pool members can use to manually connect to the server closer to them if they wish.

There may be one more server coming online by next weekend based in the east coast to give us a fairly wide spread geographically (US West, US East, EU).

Awesome

I'm gonna switch back to the EU server when it arrives then =]

Someone just changed the payment address on my my account.  I have reset my btcguild.com password, and corrected the payment address.  

Here is the address the douchebag changed it to:  1CQECoaRJzjQzZ21Td6CEXGMsQAm2wiPVh  

Also, how do we change the password of our workers?

[luffy]

you have to implement the email confirmation every time the wallet is updated! 

[CubedRoot]

What?
using the email notification is what alerted me that someone had changed the payment address.

I remember reading here that you can use any password with the workers and it'll work

Just had my first problem here .. mi miners went down for about 6 hours while I was sleeping ... was a server problem or mine?

thanks

[bluecmd]

I moved my gigahash to BTC Guild, lets see how this works out.

[Dyaheon]

EU server sounds great, could definitely use one of those. Not many EU pools around right now I presume.

Will be returning for sure when that comes online, temporarily left because of the problems.

[The Koolio]

Im all for the EU servers, UK sucks for pools! Another idea Eleuthria, if possible could you impliment a quotes system on the main account page so that we can see the best rates from multiple exchanges... MtGox, Britcoin etc.

Reason I ask is it will lower crashes on some machines having to keep going to multiple pages every time I want to check my coins and general market. I have a good pc, but suffer some stalls and hangs, and I know those with less powerful system will defo be getting these if trying to do too much.

Maybe This could be intergrated into the donations system... i.e. for 1.5-2.5% givers (which I am )

Thanks

Absolutely amazing!  How long ago was this just an idea?  You wrote the original site [beta?] in a week, correct?  Went live and scaled to be one of the largest pools available in a very short period of time and have been more adaptable, creative and reactive than any other pool operator except perhaps Tycho [meaning you have accomplished these feats at least as well as Tycho which says a lot for both of you, but especially you due to the speed and agility with which you have managed this]. 

[nazgulnarsil]

quick question, what exactly does the 2.5% donation threshold do?  does it mean that stale/invalid blocks get rewarded the same as regular shares?

I've been mining for 13 hours straight with 100% usage on both gpus and temps at 65C and 67C. Is it safe to run this 24/7?

That temperature is fine for chips. Worry when it gets to 80C+ (even then it'll probably be fine). Some cards idle at like 60+

Hardware will stop itself from overheating - either by drawing less power and slowing down / increasing fan speed - or turning off the computer alltogether.

Fatigue happens if the the hardware expands and contracts a lot (increase/decrease in temperature).

I imagine going between 40 - 70C wouldn't be much of a problem tbh, though I'm not an expert.

Temperature cycling is NOT fine for anything.  It causes "fatigue" wear.  Any 3rd year mechanical, civil or aerospace engineer or materials science major will know this without thinking 1 second about it.  Since there are MANY MANY parts in a board and only one needs to fail to kill it, fatigue is a nightmare for them.  Mining is not the norm for a gaming card ... gaming is.  Gaming runs at whatever is required while you are playing and then goes back to typical idle when finished.  This is cycling over long periods of time and much few times during the life of the card.  With mining, it is happening as often as once per minute in this pool.

So, sorry, but you are absolutely incorrect about the damage temperature cycling can do, even if below 70C the entire time.

Which is why I posted up this little python PID controller for temperature control. Put in the set point and good tuning parameters and it should be able to keep temp. pretty constant even with work 'turbulence' ... needs some patching work is all (minimal py skills me)

Nice too perhaps.  Still, if you aren't driving the card through usage, no controlling of fan or other cooling will keep it hot.

FWIW, I ran a test today and did not see one connection issue and every miner idle issue was near a long poll push and further, it idle was short enough that the GPU usage % was a short drop and then back up to full again and the temperature barely fluctuated at all.  So, I don't think this pool is a risk to hardware.  Unfortunately, I was getting 3+% stale shares and that is NOT good.

Soon enough there will be two, then three servers and perhaps this issue will hopefully be resolved as well.  I use the same mining parameters with every pool [other than login of course].

Hey guys,

I really like your pool but I need to take a short break until your EU server is online.
I think that you have been doing a fantastic job of keeping the server running and upgrading it so it can handle the ever increasing load. +630GH/s !!!!!!

Please keep up the good work!
CU on the EU server.

Yes I am donating to fund this awesome pool

This may be a dumb question, but on the Block Statistics page, it says that 550 Bitcoins "Need Confirmation"?

I'm not sure what's involved in confirming bitcoins, but doesn't that seem high?

After a block has been found, Bitcoin waits until 120 more blocks have been found until the 50 BTC from that block are being able to be moved.
550/50 = 11 blocks have currently less than 120 blocks after them, so the money there cannot be paid out yet (if you donate 2,5% or more, eleutheria probably gives you a "loan" from his own pocket, until the 50 BTC from that block have been confirmed so you can already pay out directly after a block was found)

Thanks for the ego boost, I needed it after this long weekend.  Yes, from the time I downloaded pushpool to the time I brought the pool public with the full frontend was about a week.  The pool will have been open for one month on June 9th, which is the same day I expect the second server will come online.  A third server is being added on the US east coast at roughly the same time, so I have 3 days of setting up the code to link multiple servers together so they're all working on the same round.

[eazolan]

Hey Eleuthria, I've got a general technical question.

Since you said bitcoind wasn't putting much of a load on the server, how come you don't run multiple bitcoinD, each mapped to a separate port?
