Hi all
Maybe anybody knows how to stop cgminer in SMOS 1.3 remotly?
I tried to stop it via putty, but error occurs:
root@smos-1:~# mine stop
Stopping mining processes...: mine..cgminer api failed...
root@smos-1:~# gpumon
root@smos-1:~# mine stop
Stopping mining processes...: mine..cgminer api failed...
root@smos-1:~#
maybe log file may help, where it could be located?

OMG orphaned galore 
What causing this?

UTC does NOT have a DE-centralized network anymore.Congrats to miners insisting on just one (Nitro) pool.
Nothing wrong with the Stuhlman here,but this needs to change.Otherwise miners are going to see more orphans,who try to keep mining in other pools.That's what I suspect.
Why not somebody create P2P pool(s) for UTC? I'm not technically talented but I keep asking that question...
I've moved to leetpools since last week because of continuous dc of nitro.
I thought leetpools have this issues.

Someone seems to use my SMOS/BAMT image, but started the cgminer by hand.
I've a small amount of kh/s on the smostest worker there, looks exactly like SMOS has startet his cgminer in the background.
(seems a change from BAMT to SMOS that cgminer process is monitored and started if not startet by the init script)
I don't want anybody to feel scammed by me, that was not intentional.

mined a day middlecoin to have a comparsion:
middlecoin = mined BTC for 75 UTC.
if i mine UTC i get 150UTC in the same time.
so utc seems still 2x more profitable than others

You need quite a bit of system RAM as the miner builds the OpenCL in system memory before passing it off to the GPU. If you have a 4GB GPU, you will want 8 GB of system memory, or run the cards with 2 threads (-g 2) and half the memory. This actually applies as you go up in number of cards as well. My baseline is that the machine has to have at least half of the ram of the SUM of all the GPU's in the machine. My miner with 4GB does okay with 2 4G cards, but even adding an additional 2GB card gets funny (I've found some workarounds, but it's a kludge). One other miner has 4x 2GB cards and works great with just 4 GB system memory.
Is there any reason the miner has to build the OpenCL in system RAM in its entirety? Seems like if this limitation was fixed a lot of us could get better speeds. Why can't it use the paging file if this is all that is happening?

Anyone using R9 270? what settings, im running "OK" but im trying to reduce stales, currently 3% stales
270x, i have 2.9% stales.
mind sharing your config?
im curious how similar we set it.

I found I earn twice as much solo mining
even tho its a bit of hit / miss
I just keep one rig on each pool for comparison
in all honesty their are 2x pools that are defiantly keeping half the payouts
when other pools are paying out ~250 coins per worker ( 6x R9 290's )
I am getting only ~100 coins from 2 particular pools
and my solo rigs are getting around 400 coins a day average between them
some make 200 coins
some make 600 coins

Don't forget the newcomer
New pool up and kicking at: http://thepool.pw/ultracoin/
First blocks found, and payouts sent, looking forward to be accepted by this great community!
1% fee Also, 50% of pool fees will be paid back to help community ongoing or new projects on a weekly basis.
You have 1 miner....I'd join in if there was a powerhouse there, otherwise it's going to take an entire day to find anything.
I found 2 blocks solo mining there today while testing and tuning things, more than what I make mining at crowded pools, I think with the current diff, might be better to mine at small pools!

To point 1 and 2 above; yes I had not noticed the higher efficiency on the comparison page. I do not ever intend to provide improper information. Another found and posted right below me (Puycheval), the R7 250 was doing 2.47 kh/s @ 35w. It would seem then an N = 15 would possibly be the last GPU point. However, even at 14 it seems there are only 1 or 2 GPU's that are efficient?
To point 3. Whew! At least there was something
Thanks for the reply with more information also. Glad to see you post!

The R7 250 2GB from MSI is a fantastic little card for High N factor coins, but the current champ is this little Sapphire R7 240 4GB version. My theory was low shaders and high memory would be good, and it truly turned out very well. The GPU mining software needed some additional features to be able to work at higher N Factors, and I was able to find what I needed and implement it into YACMiner thanks to Kalroth (who got the feature as a feature request on his version of CGMiner) : --raw-intensity. It allows such fine control over how much work is going to a card that I was able to up the output ~ 50% compared to mining software without it. The reason is that the -I setting sends work to the GPU at a rate of 2^I simultaneous threads. Well, the optimal rate for that card was 3072 simultaneous threads at Lookup-gap = 4, which fell halfway between I = 11 and I=12.
You can get a decent hash rate out of most any card - just the newer ones tend to just work better. N=15 and N=16 will be no problem for GPU's either, provided they're high memory cards and you have the system RAM to allocate the whole buffer in one shot (-g 1)
Thanks for YOUR CPU Minner Thirtybird
and thanks for that read so I shot my self getting R9 290's by the sound of it :S
ps. is the card your after the one with 2,688 shaders ?? or does it have more ??
will compile YACMiner when I get a chance and compare it with cgminer on UTC
I was using cgminer-3.7.2-kalroth with their xintensity but I fell back to stock cgminer because of Nfactor issues
throwing my CPU miners onto
./minerd -o stratum+tcp://thepool.pw:3338 -u x.x -p x -a scrypt-chacha --nfmin 4 --nfmax 30 --starttime 1388361600
at least then I know what they are making

Thirtybird, thank you for explaining, what cards do you use and would you share your settings for your cards per nfactor level?
The R7 240 4GB and R7 250 2GB on the YACoin wiki are currently my go-to cards for N-14. Unfortunately, they aren't that great at lower N-Factor coins - I think I was only getting ~25 KH/sec on UTC. At N=11, the 384 shaders are all busy all the time, and that's as fast as it will go - end of story. Once memory becomes the limiting factor, they start to shine, and realistically, that's N=14.
The ideal card has a decently high shader count, 4 GB of memory and overclocks well. I know of one such card I would love to get my hands on, but it's been discontinued, and noonse is selling them on ebay... (and no, don't ask me which card it is, all I need is all of you trying to buy it when someone finally does put it up for sale!)
lol, nah, i wont rush to buy it, i'm satisfied with what i have. once utc no longer available, gonna go back to scrypt. unleash my full hashpower again.... let my rig out of its cage. lol
270x x2 and 290 x1 March 11, 2014, 01:15:43 AM
Everyone has to get off Nitro seriously.
If we dont , UTC is going to only have one pool left.
Nitro needs to raise fees to 5%~10% spread the hash around.... its not healthy for the coin to be that centralized.
Thats not good!
By mining there you are hurting the very coin you are mining.
I personally mine on leetpools, I love it, great community good admin.
But this pie chart is causing un-necessary orphans and network instability for other pools.

Whats the hash speed atm for a single Sapphire R7 240 4GB?
I only have N=14 info - it's on the wiki. It won't do well at N=11 for UTC due to the low number of shaders - N=11 is not bound by memory for really any card, so you want lots of shaders
