Topic: Smartcoin Linux mining administration. [MULTI-MACHINE SUPPORT NOW IN!] (Read 105029 times)

Simple question - Simple question.

If I go into the menu for setting up a miner for example and I want to stop and go back to the main menu (this is in the control screen) How do I do this? I can't find anything with the screen options.

Thanks a mill. This one hurdle is completely holding me back.

Hi again John.
I hope you're still checking this thread =D

Just wondered if it was possible to get an email notification when the hashrate drops below a certain level for more than a certain period of time (e.g. less than 300 for 10 minutes) or maybe get smartcoin to execute the lockup script if this happens?

As what i've been noticing is one of my cards may go down but smartcoin wont pick up on it because it's only one card.

Thanks!

Hi,
Can anyone tell me to go back to the main control screen after I have gone into an option?

Thanks.

hmm, so i used the init.sh for overclocking, but everytime i make changes and restarted smartcoin, the new changes never work..it keeps using the old settings from init.sh

any clue?

I ended up reinstalling everything and Smartcoin now works well for me in LinuxCoin.  The first installation turned into a mess and I decided to start afresh.  Thanks for the suggestions!

Nice simple test, definitely try that. Did you use the patched unetbootin and set "space used to preserve files across reboots"? And are the GPU's listed in aticonfig --lsa?  I believe you will also need to be root to install and run smartcoin in Linuxcoin and to do that over ssh look here:

That should solve those issues - though I gave up on getting it to work consistently in 0.2 final.  The new version just doesn't seem to be set up for remote use.  But Smartcoin works great in Ubuntu.

change background color on desktop reboot to see if persistence is working ,  if it reverts back then it isnt saving .

I am having trouble getting Smartcoin to automatically identify my GPUs.  I just set up LinuxCoin on my machine so it is most likely related to that.  (Smartcoin had been working beautifully on my HDD before the switch to LinuxCoin.)  This is the error message I get when I try to add the GPUs manually from within Smartcoin (hey, it was worth a shot) and then start mining:


(The last couple of lines appeared when I tried re-installing Smartcoin.)

Also, I set up a simple profile yesterday and it seems to have disappeared; perhaps it's not saving to the persistence file?

I would appreciate guidance from folks who have got Smartcoin running successfully on LinuxCoin.  Thanks!

UPDATE: It turns out OpenCL is not identifying my GPUs at all; only the CPU shows up when I run clinfo.

I did not know they would show up by disconnecting. I opened up another root terminal and typed screen -ls and did not find any others. I will try that next time I fire up Linuxcoin/Smartcoin.

Yes, I set up worker accounts. Yes, I set up a manual profile (not automatic). Yes devices and miners are present in the database. I also selected the active profile. They work because I know I'm hashing at the correct rate as evidence from the Pool website and GPU temps rising. Just no info other than fan speeds and GPU temps.

The reason I wanted to see the miner screens is because cgminer I believe will provide more info than Smartcoin will.

Would I be better off using cgminer by itself and not using Smartcoin? It has Fail over and uses multiple threads already.

The miner instance screen sessions are hidden in the background, but you can view them at any time by disconnecting from smartcoin (from the control screen, or using the Ctrl+A D key combo), and typing
There, you can see all of the individual miner instances.

Normally, you don't need to worry about the individual instances as the status screen should give you an overview of the miner instances.  There may also be a chance that smartcoin isn't yet configured correctly. Have you set up worker accounts? Have you set up a profile yet (or are you using the automatic profile?) Are your devices and miners present in the database? Are you sure that the correct profile is being selected?

I was running a root terminal session from Xwindows. whoami reported as root. Smartcoin was installed as root and .smartcoin dir was installed in /root. Also started up from the /root dir. The only screen sessions were the main smartcoin config screen and the smartcoin stats screen. Should have been 4 cgminer screens as well but I'm not sure if that is the way smartcoin sets up screens or not as I'm really new at using it.

Were you logged in as root or as a user? My Linuxcoing rig showed the same symptoms if I was not root.  The screen sessions run in a root socket and are not viewable as user and the status screen showed only gpu status, no hash rates.

I do not have a screen shot as I gave up for now and went back to Windows 7. I did hit ctrl + a and then 1 and was on the screen you are talking about. I had fan speeds and temps, but no data below that. According to Deepbit's website they were hashing at the correct rate.

Is there an option I'm supposed to set for it to work with Smartcoin? Like text only output or something?

Would like to get as much info together before I go try it again. Down time = less BTC.

Also, I did not notice any screens for Cgminer itself and thus as well Phoenix when I tried that (Phoenix did output data). Maybe that is normal, but would be nice to be able to toggle to the miners actual screen display for other info not normally displayed in Smartcoin.

Thanks for the report - yes, its known that dependencies are ignored for now - I will fix this at some point once I find a graceful way to do it across different distros

This isn't hard to do, but we have to know what linux distro you are running.
Also, why would you want to use vnc instead of ssh?

Are you sure you're on the status screen tab? (ctrl + a then 1)
Can you take a screenshot of the problem and post it here?

Thanks for your feedback on everything, I'll try to respond to your comments:



I'm currently in the middle of building another mining rig right now.  I only had one rig when the multi-machine code was written and my testing time on other people's rigs was very limited.  I'm going to continue to improve the multi-machine stuff once I get my other rig in place (should be about a week from now)


How inconsistent is the CPU usage for you?  Mine normally varies by about .2 or so


On a remote machine, there is no extra code being executed - the only difference should be the extra communication overhead, which should be fairly minimal on the CPU load.  Though Its not 100% clear to me what you are saying above... 


Regarding CPU usage, smartcoin will definitely use more CPU than running instances manually. This is because it is running a loop on each instance, monitoring for failover, lockup, etc - which is pretty CPU intensive.  Under Edit Settings->Machine Settings there is a "Status screen loop delay" setting that you can adjust for each machine that will greatly help your CPU load.  It injects a delay in each loop iteration so that you don't pound the CPU so much.  I usually run mine at 5 seconds,  but you can go as high as you want (of course your visual refreshes will be slower as well)

Regarding a killed process, its definitely not smartcoin killing it - smartcoin will only kill the entire screen session, and start a new one - it has no code to kill only a single instance (it sould be something at the OS level which kills it..).  Whats the memory usage when this happens?

If your machines are secure (no wallet.dat or anything personal laying around) and could give me some temporary ssh access, I'd be more than happy to help you figure out what is happening

a) Yes, some work is still needed - though as I've mentioned earlier, smartcoin is definitely not killing the miner instance.
b) see if the Status screen loop delay setting helps
c) I do 3 cards with 4 workers very often - and I've personally tested 48 instances on a single-core p4 (3 cards * 16 instances each) with no problems at all (other than very high CPU usage, which would be expected).  Also, my mining rig (soon to be more than one rig) is dedicated, and therefore have no experience in keeping a usable GUI while mining. Have you messed with the phoenix aggression setting at all?




I'll be messing with optimizations pretty soon,  I'll definitely give this one a good look and do some actual benchmarking.



1) Can you explain what you mean by split the screen?

2) There are apparently some issues left to resolve with the persistent SSH connections, and this is undoubtedly why your remote miner status screens stop refreshing after a while.  This will be my first priority once I get my second miner put together.''


Thanks again for all of the feedback!

Hey guys - I was away for the last week so I'm going to go over the backlog and make sure I address all questions that I missed on my break.  Thanks to those that stepped in and answered some questions while I was away!

It depends on which operating system/distribution you're running. If you're running Ubuntu, you can follow the instructions I posted earlier in this topic:

Has no one a solution to make smartcoin automatically autostart after computer-restart?
