is it normal for CGminer to shuffle pools order when I remove pools via API ?

here my story:
- CGMiner has 10 pool
- the active one is pool 3
- removing pools 0,1,2 (via API call) shuffle the order of other pools, except the active one (3)

...
You are probably looking at the pool number and not the pool priority.
The priority determines which pool is mining and fallen back to etc.

When you delete a pool (API or screen) the last pool will be moved to the pool position of the one deleted.
The position doesn't affect the priority.

Can anyone tell me why sometimes cgminer is trying to submit shares that are under the target difficulty when solo mining...?

Example:
Code:
[2013-12-30 11:34:24] New block detected on network
[2013-12-30 11:37:45] Rejected 0000c804 Diff 83.9k/120491
[2013-12-30 11:39:48] New block detected on network

I don't know why it would even try to submit an 83.9k diff share when the block has a target diff of 120k... Also, why doesn't this share have the usual format of:
Code:
[2013-12-30 11:37:44] Found block for pool 0!
[2013-12-30 11:37:45] Rejected 0000c804 Diff 83.9k/120491 BLOCK! GPU 0
[2013-12-30 11:37:48] New block detected on network

I am using a scan time of 2 seconds, expiry of 120 seconds and I am mining a coin which produces blocks roughly ~2.5 minutes...

Any help/info is appreciated, thanks!

^--- Can anyone please answer this, if it's something that can be fixed/prevented I'd like to take care of it, thanks...

It seems that the last version of CGMiner that could find all 5 of my USB Erupters immidiately on every start is 3.6.4
Any newer version of program finds randomly 0 to 5 devices. Sometimes it happens certain device is not found even
after few hours. What exactly is changed after version 3.6.4 that affects USB Erupter detection? Im using Win7 64-bit
but issue exists with WinXP 32-bit as well.

3.9.0 finds all 22 of my BEs within a minute or two on restart pretty reliably (win7 i3 box using powered 7-port USB2 hubs and an fan to keep them cool). I also am running cgminer 3.3.1 to mine scrypt on a gpu (it doesn't see my BEs), and cpuminer using just 2 threads mining a cpu-only coin just to keep from wasting available cpu cycles Smiley  (I found cgminer had problems managing the BEs if I used more cpu threads mining).  I have 4 antminer U1s running on another machine using a forked version of cgminer since they don't play well with BEs at the current software level of maturity (they are a relatively new device that unfortunately share the same USB ID as the BEs, but the 4 are as fast as my 22 BEs!). 

Bottom line - I've had good luck with the newer versions of cgminer - great devs!

any idea of why GPU and altcoins are not supported anymore?, is by FAR the most profitable!
and I mine BTC with asics, LTC with GPUs and a lot of alt coins as well.
I don't understand why GPU mining, which is the most profitable one, was discontinued.

thanks
I had read that a while ago, it says he will do it, but not why.
why keep supporting something that does not generate money and kill what is generating money, that is the alt coins.
I make 10 to 1 in altcoins vs bitcoin mining.
and i have several asics, but they are pointless because they are too expensive, takes way too long to get here an make them work, by that time, the difficulty is so high that they produce next to nothing, in altcoins that doesn't happen so fast, so you can do profit, that's why I ask that.
of course he can do what he wants is his program, is a great program, but i was just curious, nothing more.

I'm not maintaining mining software to help people make profits. I'm maintaining a bitcoin miner because I believe in bitcoin, and while miners are primarily interested in making a profit from mining, I'm interested in promoting and supporting bitcoin, which needs miners and mining software.

So idealistic, you'r mine hero. You cant blame people that are raised with Fiat money, keep thinking in Fiat. Most People are about gaining more ,more and more most dont care atleast thats what they learn from the tv/social media and school. I Hope one day the autodidacts/people with utopia thoughts are world leaders. The fiat thinking people point fingers @ bankers, people with big money but when they have the same choice they will probably pick the same shitty Capitalism decisions as the Legal thiefs aka bankers.
I ask everybody with common sense why would a person that steals 1000 dollar from a shop gets months in prison and another person who robs the community to fill his pockets with 200k+ a year gets a bonus?
From this point of view the world is just sick how it works.
We should Honor Roger Ver who just gave millions usd in bitcoin away to people to promote bitcoin. just my 2 bitcents.

of course he can do what he wants is his program, is a great program, but i was just curious, nothing more.

Did you read the whole thing? It DOES say why. Let me crop out a few parts:

I am making a conscious decision and taking a stance to only support bitcoin by doing this and will consider all discussions regarding alternative cryptocurrencies as offtopic from here on. It is absolutely clear that we are in a stage where only ASICs matter in mining bitcoin, and cgminer is moving with the rapidly changing landscape that is bitcoin mining.

I honestly think all the alternative cryptocurrencies will go nowhere. The only reason to mine them is to find something that can be profitable by converting it to BTC.

The BTC difficulty is increasing because more and more people are buying newer and newer hardware. The network doesn't just increase by 500x in a one year span without people buying the hardware, and mining on them. CGMiner is at the forefront of running those millions of dollars of hashrate, BTW.

And as far as your ASICs are concerned, it's not Con's fault people bought a bunch of BEs or a Jalapeno and realized they're too expensive / hard to maintain to successfully mine any coins from them. Those ASICMiner devices have always been overpriced. ASICMiner and Avalon units consume way too much power. Those BFL Singles are decent devices. Those AntMiners look very promising. KNC or BitFury are amazing devices. I dare you to ask anyone who has any of those and see if they're losing money.

Hello Ckolivas
I understand your point of view, thank you for explaining it.

Miners always where a not very welcome necessary evil, I saw it in the labitconf conference in buenos aires, where practically the entire mining thing was avoided at all cost by the pure believers in the coin.

The truth is... mining has become really expensive business now, and great part of the people involved in it will expect profit in return of such a time consuming job.

I have 1 farm and i am consultant for another 4, and takes about 60% of my time, for such a time consuming task I expect to get profit,  and while I keep btc for long term savings, I exchange a good part for fiat to live in the mean time Smiley
I hope some day I will be able to pay everything in btc, but we are far away from that just yet.

My V1 Blades have paid for themselves a few time over - they've been totally solid and reliable, and just hash away in the corner with zero intervention.  Same with the Jalapenos. 

What is annoying is the ASICMiner Cube - it's unstable at best, uses quite a bit of power.  I'm not sure it'll ever pay for itself, but this winter it's keeping the living room about 2C warmer than usual this time of the year, and all summer it'll cost nothing to run thanks to free power.

ckolivas any plans to do a antminer firmware like you done with avalon and knc miner ?


I echo this, compiling the custom version with Antminer support is very difficult and (in my experience) far from stable. Would love to see the Antminer drivers integrated into the official CGMiner.

Im also not in this for the profit. I know im never going to make any ROI on my set-up, but I like building and maintaining it and like to "support the cause" that is Bitcoin Smiley

I know how difficult is calculated, I have been on this for almost a year, as I said before, i build several farms (5, one is mine, the other as a consultant/technician for investors) and the only ones making real money are the altcoins, the only way to make real money mining bitcoin is buying the chips and produce the rigs yourself before anyone else, or better.... design the chips yourself and don't sell them, use them.
I will get ROI with my Fury's probably between febrary and march, I already achieved ROI with my Blades, but you know what, I can make ROI in alt-coins in 3 months, sometimes less.
I never talked about loosing money, just not earning enough to make it worth it, period.

I'm waiting to see their code synced up with the current master cgminer before I can do anything with it, but also this happens to be one of the busiest times ever for development (behind the scenes), and I'll be travelling next week, so I can't guarantee timeframes on anything right now.

Only because the price of BTC has risen.

However, you lost BTC. The BTC price paid for said items at the time they were bought is greater than the BTC they have produced.
Thus your profit is less than if you had simply bought BTC instead.
(also you need to subtract the running cost and time mining that would not have been necessary if you only bought BTC)

Well, no, that's false, but hey don't let facts get in the way of a good argument.  Roll Eyes  I've never bought BTC for fiat, every BTC I've mined has been reinvested or cashed out to fiat.

Quote

(also you need to subtract the running cost and time mining that would not have been necessary if you only bought BTC)

Agreed on the first point.  

However, my running costs are essentially zero when averaged out across a year, and over the year I've been mining I've spent essentially nothing in fiat to keep my BTC production around 1BTC every 6 weeks.  1BTC every 6 weeks means I can keep up with increase in difficulty by buying new hardware, and sometimes my older hardware is sold to top up that BTC fund - I sold my 10 Block Erupters and bought two BlueFurys.  Selling the Blues paid for the 10 Antminer U1s.  Without spending a fiat penny I've gone from 3.3GH to 5GH to around 20GH.

You also have to consider that I'm not really in this for profit.  I have a good job that pays me enough that I live comfortably and have enough left over at the end of the month to not only save, but spend on my hobby of building PCs and buying little things to tinker with.  Mining is a hobby.  Some people play games on XBox.  Some people go and piss £100 up the wall on a Friday night.  I mess about with my miners.
