Topic: [20 gh] NMCBit pool 3% fee prop 6.6% PPS - page 33. (Read 63693 times)

Ok,

So should I change it?  I got ready to, when I realized that it actually ASKs for a bitcoin address, not a namecoin address, and some of your previous posts mention paying out in BTC, which, for right now, is fine with me.  Let me know if you want me to put in a NMC address, or leave it as BTC.

Perhaps you should put that on the page as well; both an NMC address, and a BTC address, with like a checkbox for whichever the miners want to be paid.  Especially with the merge coming up.

Also, did you change/remove the 'I'm mining at' bar/code?  I just tried to put it in, and either I'm not a high enough member yet to display images, or the code/link is broken.

Thanks,
CRYPT

Thanks the code for checking if it was BTC address has been lost need to replace it.

oops,

Wait, I just realized that the wallet I gave you was a bitcoin address... hhmmmm

I am running a namecoin wallet on my RIG2, perhaps I should go find that...

CRYPT

J,

I've just sent 2 workers with ~300Mh total your way...

Good luck,

Luck has a funny way of returning to you in the long run, the sooner we get this run of bad luck out of the way the better

I have had a boat load of bad luck in the last 24 hrs.  I can see why many have thrown in the the towel, well I'm not quitting even if I get hacked and all the data is lost since the last backup, I will not stop I will not give up!  I will keep doing keep work keep plugging until my luck changes and those that where with me while I was down on my luck will understand the meaning of rising tide lifts all boats.

With that I would like to thank all of my current supports for sticking it out even when our luck with finding blocks have dropped.

Davinci,

I appreciate where you're going with this...

Sorry 'bout your recent run of bad luck, but keep in mind what Ford said:

"I thank god for my customers, because they keep buying my cars, even though I never finish building them..."

There are a lot of quirks to work out, unforseen things occur (but you do need to be mindful of the 'seeable' things, ie. backups, off-line testing, regression testing, etc).  Don't loose the faith.

If you'll send me the information about your namecoin mining operation, and the gui-miner that you've put together, I'll look at it for you, and attach one or several of my rigs... I've a 30 Mhash laptop (both CPU/GPU) that I'll dedicate to connecting to/testing your namecoin pit today (once you send me the info), and if that works rather stable-y, I'll consider moving my 325 Mhash GPU over.  Once they're off back-order, I should have 2 x HD6990's coming in as well. Again, depending on how this initially goes...

I missed the first couple years of bitcoins... just got into them in June/July - but I love to tinker with it.  Your quest is truly what motivates me, which is the 'being on the ground floor' of something.  I'm not in bitcoins as much for the money, as I am for the 'learning and exploring alternative currencies' portion of it. 

If you've written anything on your thoughts/opinions on the whole fiat currency, I'd be interested in that as well.

I know you're going to be busy with the recent issues/upgrades.   When you get some time, shoot me the information and/or links and I'll point some of my computing power your way:

Damn,

rough going ! Good Luck man

Can you post on the forum when everything is up and running again,

Thx

Brat

Well I just lost a lot of work

The web site is down because I deleted the hole directory when I tried to sync it with my windows folder it deleted all the files remotely and I had no back up.  

got it mostly up and running but lost a lot of work! 

Ah well I was trying to be more productive than working in terminal with vi and grep and the rest was very slow going.   So I got WinSCP and syncted up folders to work in windows and ending up deleting my remote copy.

Well with a real editor in windows I can quickly get it back wish me luck.

Davinci,

I know you are busy, but

Just to let you know, smtg in your database is hanging

I had all but 2 of my miners disconnect with an rpc-stream error

And the statistics page hasn't updated for quite some time, even though the total amount of shares is correct and my total shares on the Dashboard also seems right

You might want to take a look

The problem is not paying it the problem is creating a pool that can support that kind of hash rate.  As far as I can see there is no fracking way mysql can support that kind of insert per second without being clustered.  What I am looking for next is a way to do select statements from a stored procedure to a remote sql database  (MS SQL Server does it).  This way I can create a MySQL server that has only flat data such as stats and many pushpool DBs with worker and share tables.

I will probably spend less than that but as I will only do it on a PPS and take a bigger % off the top than normal just so the miner is more profitable in my pool.  The people who have been with me since the beginning will be getting more than those that are band wagoners because they risked more and I respect that since they have no idea if I'm going to work my ass off to get this working.  Loyalty goes a long way with me.

Cheers

Have you thought about the huge number of bitcoins that you could have to pay ?

A simple number: 500 Ghash * 1 month = 8.5k BTC

You must be very rich if you are thinking in doing that 

Cool thanks send me an address to send you 2 BTCs.

Cheers.

Updating the database doing large queries trying to put together static data, also adding stored procedures to lighten the load this caused a lot of short busts of down time.

Going to bed now so it should be good.

This is one of the guides I used for tweaking mySQL - http://www.mysqlperformanceblog.com/2006/09/29/what-to-tune-in-mysql-server-after-installation/.  I'll save you the hours of tuning options and restarting mysql and tell you that innodb_buffer_pool_size is the only variable that made a difference and right now we have it set to 75% of our server's RAM.  This assumes you have your main shares table as innodb, which most of us do.

I didn't choose ext4 for the database, and I understand there are some other filesystems that may be better for raw mysql performance.  I think XFS is arguably better.  Anyway, changed mount options in fstab to "commit=60" and "noatime" to reduce the overhead on write operations.  This frees up the drive for more iops for mysql if it has to go to disk.  This reduced my await times by a lot.

I have a lot of connection problems tonight

At the moment, 5 out 9 miners are hashing away at their backup pool

Any idea what might cause this ? For a couple of hours all went smooth, but last 2 - 3 hours I have seen them go on and off NMCBIT

Brat

hmmm its alright

By paying people bitcoins and namecoins for mining namecoins only I will come out of pocket for the bitcoins until the merge mining starts this way I have the edge!

Thanks man you are a life saver I was wondering about taking the system down to do some alters.   I'll check out oak as for buffer pools how do I do that?

You put the db on an ext4 drive?  Why what tweaks can you do to a filesystem?  Give me a few more hints and I'll send you a bitcoin.

Once our pool got above about a couple million shares I had to do major database tweaking.  The 3 things that helped the most were COUNT(*) instead of mysql_num_rows, indexing the columns in a table that get the most action based on the statements after a SELECT - WHERE xxx, and then trying to fit the whole database in RAM with huge buffer pools.  mySQL locks a table from read and write if you try to add an index, but there is a tool to do it without any disruption in service called oak online alter table.  I did a million other tweaks to my ext4 mount options, php code and to mySQL variables that all add up too, but that would take a novel to explain.
