yo a great place was hacking at btc with my low end crap and came back here doing much better thanks

Is there a place to see what formula you use to see which coin is more profitable to mine? I don't seem to agree that FTC is the best now. Coinchoose says the same

look at coinchoose adjusted for stales, it agrees.  Going with a straight profitability is fine if you can expect 100% PPS somewhere for each coin, but if you're counting on finding blocks then stale/orphans have to be factored in as well as faster coins causing more rejected shares.  that all lowers the actual profitability, i'd be interested to see flound's actual stuff though.

Implementation of profitability or auto-switch history would be nice.

I mean something like

25.06.2013 1:00: LTC profitability is 1.42, switching to LTC
25.06.2013 1:32: FTC profitability is 1.55, switching to FTC
...

[gnomicide]

So which new coin is being added this week?

It's on the list.

well i've been mining on your pool(s) for the past 3 days & i've had a blast so far, excellent work

I don't think anyone has had as much fun as you. My laptop won't cooperate at all anymore

Do you think you will end up opening a SHA256 multiport? One that utilizes currencies like Bitcoin, Bytecoin, Terracoin, PPCoin, etc?

I have lots of fun too!

Better to get a "full" selection of scrypt coins than to partially-implement both types. There are still missing scrypt coins that spend time in 1st place, like NBL and BTB. We shouldn't be in a position where we consider manually switching to another coin for a few hours while it's at 300%, due it it not being supported.

Plus, as already mentioned, BTC isn't worth adding without a high hash rate.

Sorry to hear that, condolences for the laptop's family :<

Is it just me, or is the multiport somewhat unstable today?

I've got my miner set with port 3334 as my first failover pool, and I've noticed it in use on several occasions thus far today.

Setting a failover might cause issues. I've found that when multiport switches currencies and I have a failover, it switches. Make sure your settings are set so that when multiport "comes back up" that your miner goes back to it. It goes down for a few minutes during currency changes.

From what I can see it does appear to be switching back to the multiport eventually, I just noticed once or twice today that it was mining on failover for considerably longer than the minute or two it typically takes to switch coins.

Yeah, I noticed this earlier.  It's a result of a bug in the switching code.  I'm going to fix that tonight.  Basically what was happening was it was doing the 'switch' every 2 minutes, even though it was staying on FTC.

While agree to a point with what your saying I think some of these estimates are off.  Wdc according to coin choose and here sits at almost a 30-50% decrease in profitability due to stales/rejects/orphans.  From my experience mining wdc exclusively I only get about 8.5% stales/rejected and know there isn't that many orphaned blocks to make up that difference.  I've actually made quite a bit more revenue mining wdc instead of FTC for the last few days since my actual results are much much better than what multiport suggests.  I also would love to see what calculations are used to figure in that profitability.

+1 I would also be interested in seeing what percentages are being assumed for the stales and orphans.

Sort of an odd bug: My payout threshold is set to 99, but payout today occurred at 95.

That's..  strange.

Higher payout thresholds are available now for all coins.. (up to 999)  forgot to announce that.

WDC:

Code:

mysql> select count(id) from winning_shares where confirms=-1;
+-----------+
| count(id) |
+-----------+
|       882 |
+-----------+
1 row in set (0.01 sec)

mysql> select count(id) from winning_shares where confirms>120;
+-----------+
| count(id) |
+-----------+
|     12842 |
+-----------+
1 row in set (0.00 sec)

So we have 882/12842 orphans.  That's 6.8%.

DGC:

Code:

mysql> select count(id) from winning_shares where confirms=-1;
+-----------+
| count(id) |
+-----------+
|       205 |
+-----------+
1 row in set (0.00 sec)

mysql> select count(id) from winning_shares where confirms>120;
+-----------+
| count(id) |
+-----------+
|      3006 |
+-----------+

205/3006 also = 6.8% (interesting..)

So, the profitability calculation should subtract around 7%, minus whatever stale percentage we're currently at.  Right now that's normally around 5% from what I've seen (I don't have historical stats on this, though, and the number of shares kept in the DB for WDC and DGC is fairly low due to the low difficulty.)

I'd say 15% for both should be fairly conservative.  We're currently at 20% for DGC and 25% for WDC.  (The extra 5% for WDC was based on it having slightly faster blocks than DGC)

It only actually goes down for 2 seconds, it shouldn't be a few minutes, although I have seen up to 30-45 seconds on my miners.  I bet there's a value you can tweak in cgminer to control how often it checks to see if the higher priority pools are back up.

I also fixed a bug recently that was probably hurting our profitability -- there was a bug in stratum where for some reason it would start handing out inhumanely high difficulty shares (like with diff of 3000+) to some workers.  So I put a cap on the scrypt vardiff at 256.  I've also reduced the minimum share difficulty to 16 on some ports so the slower miners could submit shares faster.  I plan to do this with all of the coins that have vardiff enabled.

Awesome update! So far things have still been pretty stable on my side, although I am also getting the 1-2 min disconnects during pool switches (it keeps pinging the pool but sees it as offline for a minute or two before it catches on again).
