Thanks to everyone who has waited or helped, Blakecoin now has the following official pools

Merged Mine Pools *Currently BLC+PHO+BBTC+ELT+UMO+LIT

The pool has PPLNS payout, fixed 1.5% fee and is hosted in Frankfurt with a Gigabit network connection

all pools support stratum

cgminer for pool or use one of kramble's miners for FPGA's

any problems with the pools pm me or make a post here or in one of the main threads

Many thanks, pool is running well (and this post gets it on my watchlist, which is my excuse for a dumb post).

[gymnastico]

+1 

[sprinkles]

Cool.
Have moved my hash over to help balance the pools.

[BlueDragon747]

nice!

pool had an issue between 3am-5:40am this morning, I have made some code changes see if that helps  

details:
eliopool had a stuck socket connection and was caching the shares but not inserting them into the database tables due to the socket error, I have added some code to close the socket if it times out over 300 seconds hope this fixes the bug/issue 

[Manwe]

What is the hashrate of E3 1230 V2?

[BlueDragon747]

What is the hashrate of E3 1230 V2?

CPU's can't keep up with GPU/FPGA in terms of hashrate

11000 khash/s on a Intel i7 2600k as an example of quad core/8 thread cpu

Edit:
I removed CPU from the title as it would be very hard and expensive in terms of power to mine Blakecoin with a CPU with the current network hash rate

[BlueDragon747]

Server just crashed looking into it now

Edit:
ok should be working fine again was an issue with an out of order share in the share's table 

[gymnastico]

hi BlueDragon747, the pool (site) Failed to connect to database

[BlueDragon747]

hi BlueDragon747, the pool (site) Failed to connect to database

it was the stuck socket again  

reduced the timeout delay to two and a half minutes  

[BlueDragon747]

Still getting intermittent share order issues which I am still working on 

currently I have plans to release another pool in New York but getting the pool code stable first and updated on github, also need to retest my setup/run scripts for Eliopool on ubuntu 12.04 and release those on github 

any problems just let me know 

[BlueDragon747]

Trying some new changes to server code

server will be rebooted a few time expected to last no more than 45 minutes

[BlueDragon747]

ok all done lets see if that is more stable  

Edit:
still needs more work 

[BlueDragon747]

Flushed the caches and rebooted trying some other changes

[BlueDragon747]

just crashed looking at logs now

might need to re-write the share submission and open/close the cursor within the function

[BlueDragon747]

made some changes to the socket buffer size

[BlueDragon747]

still unstable

Edit:
updated the code to match latest I am testing on the New York server

Edit2:
kramble recommended adding a failover to solo mining, so my cgminer.conf now looks like this:

Code:

{
"pools" : [
	{
	        "url" : "stratum+tcp://eu1.blakecoin.com:3334",
		"user" : "UserName.Worker",
		"pass" : "WorkerPass"
        },
        {
		"url" : "127.0.0.1:8772",
		"user" : Walletuser",
		"pass" : "Walletuserpass"
	}
],

"intensity" : "10",
"auto-gpu" : true,
"expiry" : "120",
"failover-only" : true,
"gpu-threads" : "2",
"log" : "5",
"no-restart" : true,
"queue" : "3",
"scan-time" : "30",
"worksize" : "128",
"temp-hysteresis" : "4",
"blake256" : true,
"vectors" : "1",
"failover-only" : true,
"kernel-path" : "/"
}

if it was pool 1 and pool 2 you can also add:

Code:

"no-submit-stale" : true,

but not recommended for solo or mix pool/solo like the above

[BlueDragon747]

Removed the fees from the EU pool at least until it is more stable  

[BlueDragon747]

Added a pool in New York  

I was using this as a test server but have cleaned the db and fixed the front end, it is using the same code base as EU server so might still be unstable until I have rewritten a few functions  

payout was working but not tested since wipe

I am now working on a third server that I am doing all my tests on  

this should work for a pool only failover cgminer.conf:

Code:

{
"pools" : [
	{
	        "url" : "stratum+tcp://eu1.blakecoin.com:3334",
		"user" : "UserName.Worker",
		"pass" : "WorkerPass"
        },
        {
	        "url" : "stratum+tcp://ny1.blakecoin.com:3334",
		"user" : "UserName.Worker",
		"pass" : "WorkerPass"
	}
],

"intensity" : "10",
"auto-gpu" : true,
"expiry" : "120",
"failover-only" : true,
"gpu-threads" : "2",
"log" : "5",
"no-restart" : true,
"queue" : "3",
"scan-time" : "30",
"worksize" : "128",
"temp-hysteresis" : "4",
"blake256" : true,
"vectors" : "1",
"failover-only" : true,
"no-submit-stale" : true,
"kernel-path" : "/"
}

[Calhil]

Can you tell me which part is unstable? While Im solo mining blakecoind likes to time out sometimes.
