More X11 coins have been installed: CTZ, DIS, SUPER, BTCX, MUN, LGC and QBC.

Darkcoin is installed but will be mined when we get more hashpower.

Looks good and promising, nice touch identifying the workers automatically and giving them different diff :-)

The payout has been good for x11 as well.

The only thing I'm missing right now is a way to contact the OP other than here.

I've just pointed by GPU rigs over to you. I'm a little concerned at the low hashrate, or that I am being told that I am 40% of the pool at this point in time.

It's summer here and mining scrypt is just cooking me more and more.

[yaamp]

Yes, the hashrate is rather low. But now that we are fully functional and optimized, i hope to see more people mining over. We'll add more medium/high difficulty coins if the hashrate increases. But still, with low hashrate, the profitability is competitive compared to other pools, on the long run.

We just added two low diff scrypt coins: AMC and CRC

Pointed a couple of GPUs at this pool today.  Funny having two cards account for 10% of the total pool activity on X11, but I guess it just hasn't been found yet.  If after a couple of days I'm seeing similar or better returns than mining Darkcoin directly then I'll probably stay with this pool.  I do like mining on X11 as it puts a much lower heat and power demand on my GPUs which are running in computers used for things other than just mining.

I do have a couple of suggestions. 

The top coin seems to bounce around quite a bit, which is a sign of the volatility for the low diff coins.  Considering that it can take an hour or more to confirm a block for one of the coins, the exchange rate when converted may be considerably different than when the block was mined.  One way to mitigate this would be to keep a running average for the exchange rate of a coin when deciding where to rank it in the list.  Take a reading on the exchange rate once a minute and then use the average of the last hours worth of readings to establish a ranking exchange rate.  This will damp out the short term spikes and give a better chance for coins to have a similar exchange rate when converted as to what they had when mined.

Next, to avoid exchanging a coin during a dip, have a window for exchanging the coin.  Once a coin has matured, if the current exchange rate is less than the average rate when the block was mined, set an order for exchange at the average rate when mined.  If after some time period, say an hour, that order has not been filled then cancel it and place a new order at market rate.  This will help to avoid short term dips in exchange rates.

Good luck getting this pool known out there and the hash rate up.

Running for just under two days now.  Last night brought a second GTX 750 Ti online.  Now, I have four cards spread across two machines, which are always on anyway, pointed at the pool.  I've split the cards with the two best ones pointed at the X11 port and the two slower ones pointed at the Scrypt port.  First payout arrived in my wallet yesterday and it looks like one later today should be good as well.  Only complaint is that I'm alone accounting for 15-20% of the pool on X11 and about 5% on Scrypt, which is sad considering how little hash power I have.

Now, another suggestion for hopefully improving the pool, distribute hash power across multiple coins.  For the low diff coins I've seen quite often where one pool can suddenly account for most of the hash power and end up mining several coins in a row.  For quick adjusting diff coins this can cause the difficulty to suddenly spike.  When selecting which coins to mine it would make sense to avoid adding more than 50% to the existing network hash power of a coin.  This would keep the pool to under 1/3 of the total hash power of a coin and avoid such a large difficulty spike.  Send the rest of the pool available hash power to other coins.  Not mining all of the coins during a period will hopefully also avoid tanking the exchange rate when the pool redeems as there should be more players generating coins during the same timeframe.

Two good and constructive post from StuffOfInterest, considering that constructive post are a rarity here when it comes to new pools ;-).

Awaiting the reply from the pool's OP, this is interesting.
(meant in a positive way).

And before anyone else says this: "this is Stuff Of Interest" ;-)

[yaamp]

Very good suggestions. We'll certainly build on them. It's getting more complicated now with X11 coins as it involves many exchanges.

Right now, all the hashpower is focused on a single coin at any one time. But yes, the plan is to distribute it among few coins eventually when we have more hashpower. Also one of the reason why profitability is oscillating that much is that some coins dont give the same reward at every block. CTZ and MEOW are doing that. Our pool takes that into account at every block for selecting the coin to mine.

Thanks for your feedback.

Having stratum issues? I have noticed a few times that you are going down.

[yaamp]

Having stratum issues? I have noticed a few times that you are going down.

yes we fixed a bug today on the stratum software. the bug was happening randomly just after finding a block. if the new block was "blocknotified" by the coin before the stratum has the time to wrap it's finding to the db, the stratum crashed. now fixed. but anyway, we added an auto-restart in case of other problems. that should have been done already i know.

we're listening for coins suggestions, thanks

[Jmtyra]

I'm digging it. Er...I mean mining it. Just pointed my miners your way.

Something happened to coinmine.pw today, so I was happy to find this alternative.

Thanks!

Welcome new miner!

We added a few more X11 coins and also added an "experimental" X13 pool (port 3633) with only 3 coins for now. X13 looks very profitable.

[yaamp]

Just a little word to answer a question that has been asked in the email regarding block distribution among miners.

We use the regular proportional model with a little variation. Every submitted share is accumulated with its specific diff and when a new block is found, it's shared proportionally among all accumulated shares. The variation is that shares are not all deleted after a block is found. The pool always keeps at least the last five minutes of submitted shares. So that if two blocks are found within a few seconds, the second will still be fairly distributed.

And by the way, thanks to carrotX who proposed we install PIGGY. We've got two blocks this afternoon. That's very very lucky considering our relatively low hashrate.

[yaamp]

we added a good number of X11 and X13 coins.

How much hashpower is enough for DRK ?

Coins are being mined when the "Time To Find" is below 5 hours something (20 000 seconds to be exact)

We never mined DRK so far.

strategy is good,
but not have enough hashrate to get block rewards...

so i put my garden to the pool 1 hour ago.
now it's much faster and making profits.

Do u like my 0.3G garden?

Wow yes that's a big add to the pool hashpower. I even double checked the other day if it was real hashpower as the profit wasnt that good for a little while. It's back now to a respectable level.

We have relocated our servers today. That should help to lower stales and make the pool more scalable for more coins. Only the x11 pool is active at this time. The scrypt and x13 are not that profitable and werent really used. But we plan to keep an eye on x13 and x15 and activate them soon.

[yaamp]

We modified our software so it's less aggressive on low difficulty coins. It didnt matter much before, but now we're starting to have some good hashpower. Almost enough to mine DRK, if it were profitable.

Currently most of the mining is on X11 coins. X13 is mining too but with less profitable coins. Our software is ready for X15, we're just looking to add coins.

We added an IRC chat channel here http://webchat.freenode.net/?channels=#yaamp for questions or suggestions.

good job!

but i have a problem here.
sgminer always lost connection to the pool 0.  it will reconnect a few minutes later.
is there something wrong in my conf or just network problem?
