Does CPU affect how many GPUs you can run?

[philips]

I can say that BAMT (both this 7XXX version or the original one) has sometimes the tendency to crash/hang/get stuck if I access it locally.
Left alone BAMT can run for days or more, but if say, I move the mouse and wake the monitor, often the cursor get stuck and mining stops. I can only reboot.

I have fixed IP addresses assigned to each BAMT and access them only through SSH and monitor them through mgpumon (web interface).
If a reboot is needed I use coldreboot in terminal, I rarely enter in the room where the rigs are located.

Are you able to boot into safemode through the terminal?



can youpoint me to something that tells me how to assign fixed IP addresses tp my BAMT rigs.

While in BAMT (stop the mining) open the file manager and navigate to /live/image/syslinux/ where you gonna find a file named live.cfg.
Open it with the leafpad editor and add the argument I highlighted in red to the first append line.

label live
        menu label Boot the BAMT
        kernel /live/vmlinuz
        append initrd=/live/initrd.img boot=live config persistent splash vga=0x317 maxcpus=1 hostname=bamt-miner quiet vga=normal

label livefailsafe
        menu label Boot the BAMT (failsafe)
        kernel /live/vmlinuz
        append initrd=/live/initrd.img boot=live config persistent splash vga=0x317 hostname=bamt-miner  noapic noapm nodma nomce nolapic nomodeset nosmp vga=normal
...............................................................

You can now boot both in safe or normal mode.

can youpoint me to something that tells me how to assign fixed IP addresses tp my BAMT rigs.

In the lower right corner right click the Network icon and choose Edit Connection. (You can also choose Connection information to find the current IP)

On the first tab (Wired) choose your connection (something like Auto eth0) and click on edit.
Go to IPv4 Settings and choose the Manual method and enter your desired settings.

Thanks



When I treid to assign an IP I couldnt get it to mine.  It said it was mining but it wasnt showing any KH/s.  I know this is because it has no internet connection because I forgot to hook up the ethernet cable once or twice and thats what it did.

I changed the IP back to auto and it started working fine.


Does this mean I have to change some things in my router?



And do you reboot from mgpumon?  I know gpumon has some things you can do that it shows you when you press ?.  But I didnt see any options to reboot or coldreboot or anything like that.


Or is the coldreboot a command you enter through SSH?

[philips]

I just noted the current settings (used while in auto) and entered them as static.

I monitor the rigs through the mgpumon web interface, so something like this : http://wa.gigamining.com:81/mgpumon/index.html

while monitor and control cgminer by ssh-ing to them (each rig) and using screen -r cgminer command.
If needed, out of cgminer with Ctrl+A+D and use coldreboot in the same terminal.

If you use gpumon you can quit with q and enter coldreboot in terminal.

Do you know how I can change the port that I SSH into on one of my BAMT rigs?  As in, right now I got one at 192.168.1.107 and the other at 192.168.1.109.  I have set in my router to forward the 192.168.1.107 one on port 22.  This allows me to view it from outside of my local network.

But I cant forward both IPs to the same port.  So, can I change the port on one of the BAMT rigs so that I can forward it?


I know I can use mgpumon but I like doing it this way.




Thanks again!

[philips]

Hm, you can try to SSH to 192.168.1.107 and from there again SSH to 192.168.1.109.

So two instances of putty (or whatever you use), one to 192.168.1.107 and one to 192.168.1.109 (via 192.168.1.107).

Port 22 is the default port for SSH connection from what I remember.
Try to edit  /etc/ssh/sshd_config and assign a different port maybe?

Does teamviewer work on linux? That's the way I remotely monitor my rig through awkward and restrictive NATing (uni halls internet)

[ewitte]

BTW I've seen people running multiple FPGA off a Raspberry Pi which is ARM so really there isn't any limitation for CPU.  On that 1155 Celeron (G550 I believe) it runs between 1-3 cpu utilization.

Only thing with the Rpi is that USB bandwidth can be an issue and it eats into CPU time just to organise the USB stack iirc. This was an issue with soundcards at least.

As for a real cpu - anything should be ok. I run a core i3 clocked down to 1.33GHz and with only one core turned on, my PSU switches itself off otherwise

Yes, there is a version for Linux. In fact it runs on pretty much everything (iPhone too )

Thanks once agin Phillips.


So I changed the port in sshd_config and I also changed the port in ssh_config.  I think you were confused as to my intentions.  I wasnt trying to change the ports to be able to view it locally I was changing the port so that I could foreward it in my router settings so that I can SSH into it from wherever I am using my iPad.

I know I could just SSH into one of the rigs and use mgpumon.  But I like using gpumon better.  So now I can log in to both rigs and use gpumon.
