Odd GPU behavior - terminal window + FAHClient
Posted: Thu Feb 04, 2021 11:14 pm
by SJC_Steve
After getting the Client and Viewer loaded on Ubuntu 20.04, (Control is still broken), I noticed that CPU tasks were running but my GPU, (GTX 1060, 3GB) wasn't running tasks.
However, when I opened a Terminal Window and sent the command "FAHClient" I got what appears to be a log file with continually updating messages. I noticed that the GPU was now at full utilization. When I closed the terminal window, the GPU went back to 0% utilization. Upon opening the terminal window and typing the same command, the GPU went to 100% utilization. I tried this several times with the same results. I appears that the terminal window must be active and viewing the FAHClient log messages for the Client to activate GPU tasks.
This seems rather odd, am I doing something wrong in the setup for the this to be happening?
Thanks,
Steve

Two problems:
* Starting FAHClient manually omits the "hideconsole" step so you get the continually updating output and you have to leave the window open.
Check the shortcut that starts FAHClient.
* The "cd" command is required before starting FAHClient so that FAH knows where to put it's work files. In a terminal window that should be the first step.
Presumably when you manually started it, you created a new set of working files somewhere else and it ran successfully.
STRICTLY A GUESS, but I suspect that you manually edited the client.cfg file and created a syntax error. FAHClient will absolutely not run if that kind of error is present and the hideconsole functionality won't let you see that error message. All of this is a workaround for WIndows not having the concept of a GPU running in a DAEMON.

Difficult to help you on why GPU tasks don't start when FAHClient runs as daemon, you should post your logs.
The command to run FAHClient as a daemon is '/etc/init.d/FAHClient start' and '/etc/init.d/FAHClient stop' to stop it.
The current log is '/var/lib/fahclient/log.txt', the previous ones are located in '/var/lib/fahclient/logs/' and named 'log-YYYYMMDD-HHMM.txt'
That should help you provide the required information to sort it out

Here is the current log after I rebooted the system. I haven't manually modified any FaH files and didn't issue any commands to the the FAHClient, therefore the GPU is not currently operating, 0% utilization, CPU is at 100%.
Also here's the my Donor stats which shows no completed tasks since 2/3/2021 even though it's been running 24/7 utilizing both the CPU and GPU.

That log appears to be saying that there is no gpu slot? .. Which would match with the single active user .. but not with the gpu working 100% .. do you have more than one client running - would running fahclient from window be firing up a second client somehow that is running off a default config that fires up a gpu slot

In Windows i would check the running processes in task manager .. if my guess is right I would see two fahclients and probably one fahcoe_22 and maybe two fahcore_a7 or a8 when that terminal window is open and reporting cpu and gpu usage .. but I have no clue how to do it in linux

The GPU is no longer working, it's currently at 0%. It only operates when I issue the command "FAHClient" which I didn't do after I rebooted. The log is from operation with no intervention from me.
However, here's a portion of the log above, which show the Client sees the GPU, it's just not using it.

Installing the drivers from NVidia.com would fix this problem on Windows. In Linux, you can probably install OpenCL directly (See other Linux discussions).
Running two copies of FAHClient is not supported and if you do manage to get it working, you're likely to cause other problems.

Are you saying that simply issuing the command "FAHClient" starts an additional client with different attributes from the already operating Client?
Thanks,

I looked at the tasks running with FAH in the name;
Before issuing the FAHClient command, 4 processes are running with 0% GPU utilization
After issuing the FAHClient command, 10 processes are running with 100% GPU untilization as long as the FAHClient window is open. It goes back to 4 when I close the window.
So it appears that issuing that command opens another Client with other attributes?

That is what I believe is happening .. the process names may confirm this .. I know in Windows how you start the fahclient is important or it can cause issues

So, I've spent a week trying to get the latest release of FaH running my GPU on Ubuntu OS with no luck. I appreciate all the help everyone has offered but at this point, it appears that FaH is not a project for average donors running on Ubuntu. I'll go back to Boinc and try again in the future.
Thanks and good crunching.

FAHControl or WebControl are designed for the average user to run in the foreground.
FAHClient is not designed to run in a terminal window (full stop). It is designed to run as a background daemon. The installation script creates that daemon and you are choosing to override that process. You do so at your own risk. Having done that, you also suggest that you are neither an average Linux donor nor a Linux guru.

I only ran FAHClient in the terminal window in ignorance by fumbling around as it was the only way I ever get the GPU running. When I ran the install as directed in the Linux install pages, all three of the install scripts failed with various dependency problems. I am after all, just a lowly average Linux donor fumbling around contrary to your suggestion.
If you don't believe it, install a fresh Ubuntu 20.04 OS and then run those three deb packages and see how many steps it takes you to get the GPU running. Then do a write up to let us newbies in on how to get this operating. Speculating on my abilities is a waste of time.
Thanks,
Steve

Sorry. I didn't mean that in a critical way even though it sounded that way. We do (blindly) have to guess the best way to provide support to a wide variety of users.
I'd like to see a family of installation scripts named for the version of Ubuntu that it was tested on with the necessary changes so they all succeed on that version.
I suspect that FAHClient runs properly in any version of Ubuntu once it is installed in an optimum environment and that FAHControl works if Python's version is properly handled.
