OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.11.1

Very possible. Mine on the 7950 and use the HD3000 or HD4000 for your display.

Well I tried but for mining to work I had to disable the HD3000 in BIOS.
Or do you mean that I need to not have any display connected to the AMD 7950 and just use the Intel for display?

I'm a gamer and need one display to my 7950

Ok if you need the HD7950 for gaming you can't mine on it at the same time without a noticeable lag.  Disable lucid MVP and connect a cable to your mobo and then use just HD3000 for gaming. Mine on the 7950.

...
Does somebody have similar issues and if yes what can be done to resolve them?

And as always it happens at night:) I know that it can happen randomly but never during day

I run my cgminer in a loop
http://pastebin.com/Z4pG26uF
(my cgminer is just another script 'cgminer.sh' that runs cgminer with the options I want)

Thus if it ever crashes, it leaves a core and then restarts

Do something like that - if it actually crashes - so it just restarts (with a 5 second sleep)

Obviously, in my case, I certainly want this to help find bugs and help with fixing them
(so I also compile -g and without -O2) but yeah it makes it easy to find bugs and also keep mining

Is this something that can be done in windows 7 64bit? whit some program/scripts that loop and restart would be great..........When cgminer stop mining for some reason..........pool or others...........
Also i use task manager to set priority 2 real-time. ist there a permanent way to do that?

i have C:\cgminer\cgminer.exe

anyone know? i can offer 2btc for working solution

PS you are doing great work kano & ckolivas

Regards Testit

[Testit]

Try my akbash

[/quote]

i will try the new akbash, but tried the old version seems I am to dumb to get it working

Regards Testit

[hahahafr]

I've set up my own script to do exactly what you wanna do.
PM me. I'd be glad to help and assist you for 2 BTC

You could try a starting cgminer with a BAT-File:

Code:

:here
START /B /WAIT /REALTIME C:\cgminer\cgminer.exe
GOTO here

The only thing missing is a delay.
I have not tested this. Maybe it doesn't work like I think it works.

[Askit2]

The only thing about the loop is don't restart cgminer from in cgminer settings restart. It will stop cgminer then cgminer itself restarts it and the loop keeps trying to start cgminer giving you no devices restarting message in the middle of cgminer working messages. Aside from that it works and is about what I do.

This will not set realtime but will show how to set a delay.
No need for cash. Was super easy to setup. You can set any options you like mine are there yours likely wont have --disable-gpu.

Code:

:Loop
cgminer.exe --disable-gpu --api-allow 127.0.0.1 --api-listen
ping -n 15 127.0.0.1 > NUL 2>&1
GOTO Loop

ping -n 15 blah blah blah the 15 is the time in seconds for the delay. Seems accurate enough. It pings home every second.

any miners like CGMiner able to switch to a pool when rejects on one go significantly above average?

cgminer switches if it encounters 3 minutes of continuous rejects

Is there a way to make mining on a PC that has a AMD 7950 and Intel HD Graphics possible?

My Motherboard is a Z68, I would like to connect 1 or 2 Computer Displays to the HDMI and DVI on Z68 motherboard and 1 or 2 displays to my AMD 7950.

When I start Cgminer it says too many gpus or something along those lines.

Yes there is, but you will need to use a combination of parameters to these options: -d, --remove-disabled, --gpu-platform and --gpu-map. Start with 'cgminer -n' to read  what cgminer finds and then read the advanced section on gpu-map in the readme.

Sent a donation. Just started using CGMiner. Waiting for Stratum support too.

I will have my new static IP in a couple days. Will have ftp up if you would like me to host your miner files. I am on a 100/25 connection. Should be good enough. Let me know if I can help in any other way.

Much appreciate the donation

My own server is not a problem, it's me sending heaps of uploads there that is the rate limiting step and no matter where I send them the same issue occurs. Thanks though.

[-ck]

Waiting for Stratum support too.

Regarding stratum, I have been working on it. It is very much a non-trivial task to do in c so it's taking a while and I'm progressing very slowly and cautiously. Furthermore, the work generation is totally orthogonal to the current cgminer network scheduler I spent so much time creating, so it needs to rip great big holes into the current code to circumvent it. There's a stratum branch in my git tree if people want a peek but it's just code in progress and unusable.

[kano]

Found a small bug. If send a request gpurestart|0 by API, cgminer very much starts to load the CPU ~ 100%.

GPU restart isn't always going to work in all situations.

Unless there is a code bug and you've found an infinite loop - it's most likely a driver issues and if you find with your driver version+card it's problematic - don't use it.

[kano]

It will stop cgminer then cgminer itself restarts it and the loop keeps trying to start cgminer giving you no devices restarting message in the middle of cgminer working messages.

GOTO Loop

ping -n 15 blah blah blah the 15 is the time in seconds for the delay. Seems accurate enough. It pings home every second.

Or with a little more added

Code:

@echo off
:Loop
REM cgminer
Set NOW=%date:~10,4%%date:~7,2%%date:~4,2%.%time:~0,2%%time:~3,2%%time:~6,2%
cgminer -G --api-listen --api-allow W:127.0.0.1,R:192.168.0.0/24 --api-description Windoze 2> "run.%NOW%.log"
echo Sleeping for 5 seconds
ping -n 5 127.0.0.1 > NUL
GOTO Loop

So you get a log of each run also like my linux script
(of course set 192.168.0.0 to match you network - and also set it to W: instead of R: if you want to allow cgminer control from other computers on the same network)

I tried to update an old rig from 2.4.2 to 2.7.6 but 2.7.6 just hangs after the pool messages and does nothing..

I can abort with CTRL-C.. The old 2.4.2 runs fine though ?!

Here is a log:

http://pastebin.com/ACe6QDi9

I can see no problems there either, but cgminer is not "switching" into the "normal" view with the cards, it just sits at the pool "overview", saying that the pool is alive and does nothing else..

Up to the point below it looks fine ... has found and accepted shares ... but then:

Code:

[2012-09-27 13:57:38] Attempting to restart cgminer 2.7.6

In the current code that's only called by
1) You press S C Y
2) You send a restart to the API
3) Getting GPU fan speed fails

Thus it must be 3) (1 and 2 aren't possible in that log) and somehow it can't access your fan info for one of your GPUs

Maybe --gpu-map is required to fix it?

Using --no-restart will show that is the cause of the problem - but not fix the actual problem.

[ocminer]

Thanks kano, --no-restart worked, you are right, the fan reading on gpu 3 fails, even though
all three cards are 5970s, so there is actually just 1 fan on each card..

Strange that it works with card 0 and card 2, but not card 1 ?!

Maybe a BIOS error of the card ??

I actually only have the problem on this particular rig..

While I see r-pi listed in the subject, I see no instructions or downloads provided. Am I missing something?

For Raspbian, my steps went something like this:


install required parts:

sudo bash
apt-get install build-essential git dh-autoreconf libcurl4-gnutls-dev libusb-1.0-0-dev libusb-dev libncurses-dev libudev-dev yasm screen

grab latest version:

cd /usr/src
git clone https://github.com/ckolivas/cgminer.git
cd cgminer

tell it to configure itself

bash ./autogen.sh --enable-scrypt --enable-bitforce --enable-icarus  --enable-modminer --enable-ztex --with-libudev

upon successful configure with no errors, compile it

make all

upon successful compile, run in "benchmark" mode to make sure it's alive

./cgminer --benchmark

stock 700mhz ARM gets right around 118Kh/s.



[edit: added libudev-dev - thx for pointing out the miss]

[P_Shep]

EEEeeeerrrrr...

[streetuff]

well... if someone would reverse engineer the videocore there might be a possibility to write a shader for sha256 mining on the raspberry pi. but without broadcom opening the videocore that wont happen...


EDIT: on my 1100MHz arm seagate dockstar its about 200Kh/s
