[ANN] profit switching auto-exchanging pool - www.middlecoin.com

[mikeybit]

Has anyone else noticed that the difficulty on the EU server and the US server are different?

I switched my miners over to the EU server yesterday (except for 1) and they were mining on different difficulties. So I assume different coins.

However, the EU server seems much more stable.

Anyone else have any insight?

Look on last post on page 180, top of 181, and H2o's response in the middle of 181.

If you're referring to this:

There are currently some network issues with coin switching. It occasionally doesn't switch, and hangs for 20 seconds or so. This seems to happen once in every 5 switches or so.

I'm working on a fix, but in the mean time if you want a workaround, and you can are ok with recompiling cgminer, you can:

in https://github.com/ckolivas/cgminer/blob/master/util.c

change:

Code:
const int tcp_keepidle = 45;
const int tcp_keepintvl = 30;
to:

Code:
const int tcp_keepidle = 5;
const int tcp_keepintvl = 4;

These occur twice in the file.

Thanks to `Kevin on IRC for this.

It doesn't explain the difference between EU/US

[coinGeek]

coinGeek parses the main json and posts data for the individual graphs several times per hour; balances are in the last 20 or 30 lines there if you can figure out how to parse it.

Example: http://192.237.252.90/coinGeek/js/all/14Cdwieeud1tno3Vutm4Hv9RF2ytyJWPLz.js

This might be useful?

I had seen that, thanks.

I'm afraid anything I could write to try and parse that would be quite fragile - the balances are just reassigned to the same variable over and over again, so I can't really search the .js file for those var names either.

Maybe coinGeek wants to provide a JSON API that serves data for individual addresses?  

What you see in my javascript are the canvas drawing commands. It would be hard to get back to the original data because I've applied scaling, and so on. You're right hausrath, parsing that would be very fragile.

H2O has been planing to move the graphs to his servers and generate them right from his database. Those plans have been moved down the list by recent growing pains but AFAIK they will happen eventually.

They are mining different coins, one at diff 21.9M (which I think is doge) and one at 4.19M (which I think is CatCoin).

The EU server does seem to be much more stable right now for me as well. I am using cgminer 3.1.1 and have not had any disconnect or switching issues with the EU server.

I just noticed the pool is bouncing around to different currencies like crazy.  Something else I noticed was that my lower hash rate rig is working on a different coin than my higher rate rigs.  It looks like h20 is tinkering around with things.  heh..

I've been mining dogecoins now for more than 7 days straight now. I never noticed any coin switch. I often check cgminer difficulty and compare  it with coinwarz. Only match is dogecoin every time...

My personal computer just switched from a 22.9m difficulty currency to a 4.43m difficulty currency in the last 45 seconds.  My two dedicated mining rigs are both on something with a difficulty of 66 right now.  All three are pointed to the main middlecoin.com pool address.

Middle coin is on amazon servers. If you have problems reaching them you probably have network problems.

?? No one is having a problem reaching them

I've been having issues since Dec. 24.  Thought it was a GPU failing, but verified that I was having connection issues on two different rigs.  Also, removed GPU that was consistently being killed off and rig was still crashing.  Switched to different pool and everything has been running fine.  Not sure what is going on.  Can't seem to figure it out for now.  Hope to come back.  I really like middlecoin.

The unexchanged balance is going to surpass the balance

what is going on? h2o is doing some change in the server or the server is overloaded?

or...or...the auto-exchanger algo is waiting for a good time to trade

in my opinion before the changes a few days ago when the exchanger was backlogged like this, we were making better profits...hopefully that shows up in the next payout or two!

When we were mining DOGE, we were exchanging almost instantly, thus the unexchanged balance remained low. If we are mining other coins then sometimes they take up to 3 days to mature. Those of us with Middlecoin since before DOGE are quite used to it

That said, hash rates are quite low right now... everything looks fine on my end, but I'm down 2.5MH or so. Most likely our pool luck is low or I'm losing some shares somewhere

Someone should tell h2o one of his servers is mining cat and the other doge ... Wink wink

Someone should tell h2o one of his servers is mining cat and the other doge ... Wink wink

and what is exactly the problem?

[foodies123]

Both should.

I have wemineltc as a failover pool, and CGminer has been failing Middlecoin (over 165 GF errors between 2 rigs today). Anyone else experiencing this? Should I remove my failover pool?

[SimonG]

Seems like eu server is mining dogecoin and us server is mining something else, maybe catcoin? difficulty is 64 anyway.

The problem I see with this is that some people who are mining the most profitable coin will earn more than the ones mining the other coin.

It's probably due to coinshifting. I'm bot sure how the failover pool works. is it everytime main pool is dc'ing or is also when it doesn't get work for lets say 10 sec?

I think it is when work isn't available for ~10 seconds. I've added eu.middlecoin as my second pool, moved wemineltc to third tier, and added the "--failover-only" switch to CGminer. We'll see if this reduces pool switching. I only want to leave Middlecoin if its stratum servers are down for an extended period of time, like say during a DDoS.
