LinuxCoin and Radeon 6870's.....

looks like it's working well for the last 3 cards, but i'm having problems with the first one.

I've tried phoenix and poclbm

right out of the box and stock the 3 cards are doing 260mhps with BFI_INT VECTORS WORKSIZE=256 AGGRESSION=12
If i set the first card to those flags it cranks the cpu to 100%. This ends up reducing the performance of the other workers.
So I set the aggression down to 8 on the first card but now I can only get 150MHPS!! What gives?
Currently I have to run the first card at 150mphs while the other 3 are running 260 completely stock.

I've tried all different flags, both kernels and the only way these cards do anything decent is with aggression=12
how can I run my primary card at aggression=12 without lagging the cpu?
I would love some advice on the issue, it may even be worth a tip, who knows.....

I figured it out. And it had nothing to do with linuxcoin. I was being a tard. Therefore I'm not even going to post the details in order to spare people from getting them confused with significant details.

It would be handy to know if it's something someone else might do wrong, even if LC not involved. Plus schadenfreude is one of my favourite hobbies!

Hi!
Is anyone of you able to start mining remotely with NO monitor connected to the pc?
I have no problem starting it from within LinuxCoin. There I get nearly 290000 khash/s.
But it works neither with ssh nor vnc.

Does anyone run a headless mining rig and knows an answer??

Cheers,
Harm

I too would like to know the answer to this as I am going to be deploying an offsite miner and would love to have remote access to it.

Also, what is the best way to automatically start the miners on startup?

But it works neither with ssh nor vnc.

When I do
# export DISPLAY=:0
I can start mining successfully. But it makes only 300 khash/s not 300.000 khash/s!!
Therefore the cpu usage is very high, so I guess there is something wrong.
Maybe with any variables?

so now everytime I reboot I must use the persistance option?

Yes, but you can edit /live/image/syslinux.cfg and move the persistent option to the top of the list (or just delete everything apart from the persistent one).

If you get to the command prompt and type

or something similar. Providing /dev/sda2 is mounted on /live/cow and not /media/somethingorother, you should be absolutely good to go.

i want to make sure this a valid method to create an offline savings wallet using linuxcoin...

1) boot from linuxcoin iso cd on offline machine
2) run bitcoin client, note address
3) copy wallet.dat from /home/user/.bitcoin to usb media
4) shut down (wallet.dat is now purged from RAM and doesnt exist anywhere but my usb media)
5) whenever i wish to put coins in "savings" i send coins to address from 2)
6) if i wish to "withdraw" from savings in the future I copy the wallet.dat from my usb media to a computer running bitcoin, and once it has downloaded the block chain i can spend the coins.

i want to make sure i dont fuck anything up and lose my coins trying to secure them. so let me know if i have overlooked any steps or if anything i'm planning here is wrong...

I am trying to create persistance but having a few problems. on my usb drive i see sda1 and sda2, but when i try to format sda2 i get the message that sda2 is mounted; will not make filesystem here.

So /dev/sda2 was probably already formatted and has been automatically mounted...

Open up a terminal window and su to root:

Code:

sudo su -

Then check where it's currently mounted:

Code:

df

You should see /dev/sda2 mounted under /media/somethingorother. Unmount it:

Code:

umount /media/somethingorother

(obviously replacing as appropriate). Then format the partition:

Code:

mkfs.ext4 /dev/sda2 -L live-rw

Then reboot into persistent mode (don't just type 'reboot', that won't do it - you'll probably need to power-cycle the box). Et voila, it should all be there!!

Hi,
I am getting the following error, when trying to start mining remotely with ssh:

[code]
user@linuxcoin:~$ sudo python /opt/miners/poclbm/poclbm.py --user=login.worker --pass=pwd --device=0 -o api.bitcoin.cz -p 8332 -v -w128

user@linuxcoin:/opt/AMD-APP-SDK-v2.4-lnx64/bin/x86_64$

doesn't work neither...

Start mining locally is no problem at all.
Can anyone help??

Cheers,
Harm

EDIT:
Found the solution myself:
After each start one has to accept amds licensing aggreement again. As i booted headless i did not accept them...

QUESTION:
can i accept the licens remotely with ssh? VNC would be an idee, but i would like to do that with ssh...
Can I persist changes to the system?[/code]

I am new to linux, where can I find this file... Huh

you can do this in windows with notepad.

just look at the main partition after you used unetbootin to extract the ISO to it. that is where you will find that file.

I am having another problem now. If I boot the system and don't select a boot mode at the first screen and just let it time out on "default" it boots the non-persistent mode. This is true even though the configuration file for the menu indicates that it should boot to persistent mode by default... so I'm trying to figure that out now.

you can delete all unused menu options in syslinux.cfg

Is there going to be an i386 (32-bit) version of LinuxCoin?

I have a few old motherboards with Celeron 2.6 GHz -- the BIOS clearly reminds me that they are not 64-bit

I won't be able to run this on those machines, I guess.

After I deleted the (only) partition on the USB drive in PM and opened the "create partition wizard" the USB drive was not in the list of drives, at the start of the wizard it is mentioned that not all drives are suitable for getting a partition created because 4 primary partitions already existed (I cannot remember exactly what it said, and the USB drive is in use now for mining) but it would not even show the device in the list, and therefore did not allow me to create a partition on it.

Hmm.. Interesting.. I really did think this would be helpful for some people. I never used the wizard before. I just deleted the partition. Right clicked the thumb drive, new partition, set it up for fat32 and changed the size. Then click the check box for apply. Maybe it had compatibilities with your stick or maybe the wizard has a glitch. Weird..

Oh well, hopefully someone will find it program as useful as I have.

Ronin said:
> FATAL kernel error: Failed to load OpenCL kernel!". Really .. there is something wrong with that.

Yes, there is, and I think it is this.

As it stands you need to have public write access for all the directories that include .py files so

cd /opt/miners
sudo chmod -R a+w phoenix
sudo chmod -R a+w poclbm

Possibly DiabloMiner as well, I havent tried it.

I think this is because python likes to precompile an executable into the same directory as the source code.

Its not good that you need public write access and perhaps there is a better solution, but its the one I found.

There are 2 ways to run python files like xxx.py

./xxx.py
or
python ./xxx.py

The latter possibly also gets round this problem but for me is undesirable.

I'm not sure what you meant by Partition Manager is not able to create a new parition on the USB stick.... It absolutely can... just not ext4 partitions

After I deleted the (only) partition on the USB drive in PM and opened the "create partition wizard" the USB drive was not in the list of drives, at the start of the wizard it is mentioned that not all drives are suitable for getting a partition created because 4 primary partitions already existed (I cannot remember exactly what it said, and the USB drive is in use now for mining) but it would not even show the device in the list, and therefore did not allow me to create a partition on it.

To my surprise Windows Disk Manager did allow me to create the partition but it was mentioned that only 1 partition could be created on removable devices (I think this is due to the fact that Windows can only handle 1 on such devices) and the size of this partition could only be the full available size of the drive.

I used the tool I posted earlier, which allowed me to create whatever I wanted.

Hi all,

Using Linuxcoin on five boxes at the mo and think it's great.

Installed on 2GB USB sticks with 1GB for the image and 1GB as persistent storage.

I have worked out how to start AMDOverdriveCtrl (to load the correct fan profile) and the miners automatically on boot, but cannot work out how to get the initial boot to default to starting with persistent storage - consequently every reboot requires manual intervention.

Is there an easy way to set the default boot option to be the "Linuxcoin (persistent)" one?

I have looked through the boot menu structure (seemingly at /isolinux/live.cfg on the ISO) and it would seem to indicate that the default is to boot the persistent version....

Code:

default LinuxCoin_persistent

however, this is not what I am seeing - after it boots the default option, /dev/sda2 is mounted on /media/live-rw rather than /live/cow (which is where it's mounted if I explicitly select the persistent option) and tmpfs is mounted on /live/cow.

Anybody any ideas?

Cheers and thank you,

Niccy.
