Folding@home seems to be eating up to much of my machines resources. How do I uninstall it?

you can do this via


but rember that folding only uses CPU cycles what nothing else is

I don't know your situation, but I'll bet that F@H is not the culprit. It uses very few resources and step out of the way nicely when other demands come along. Perhaps you are running more than one comm flagging task -- now THAT can cause some resource issues!

You are right. I forgot that I had changed mythcommflag source code to alter the nice setting of the commercial flagging processes. I recompiled and replaced the installed mythcommfag and that seems to have helped. I'll keep on folding..

It seems to be running at the same nice level as the DVD Transcoding does... Was scratching my head when2 dvds were taking upwards 6 hours to finishing transcoding...

I ended up uninstalling folding @ home because when I run top it appears to be using 50% of my CPU when it was running and not yielding enough to the frontend to make things usable. After the uninstall things seem to be running better.

Odd. I find it inconceivable that F@H was not stepping out of the way when other tasks wanted the CPU. I've used it while recording 3 HD programs and watching another, with no ill effects. I have not seen F@H get in the way of MythTv at all.

I have noticed it will still step outof the way however,
not as much as I thought it would.
It doesn't appear to be running with a nice level of 19 when I have to do a reset. not too often but they do happen.

I had a strange recording issue come up this moring and so I did a reset after 12 days.
When I went in to check that everythig was working it was but F@H was running about 80% cpu.
I ran running processes via Webmin and it showed F@H at the top as expected.
When I looked at the actual running process it said F@H was running with a default Nice of 0.

I have seen it do this before, I just changed it to 19 and everything is happy until I have to reset.

Any thoughts as to why it seems to be running this way. It is on my MBE/FE box in the sig. and I followed the steps to install it exactly. Folding a 5 way protein that isn't due back until sometime in April.

Thanks!

I have found that on my system F@H was using up too much CPU (50%) or more even with a nice setting of 19. I am finding that the R5E50 release is using a lot more resources then the past releases and I need all the CPU I can get just to make it usable. I love a lot of the new features but, the usability has gone down for me and I have been considering going back a few releases so that I can watch some TV instead of messing around with this thing.

I think there's a general misconception of what you should see in "top" if things are running properly.

The F@H process should use up _all_ the cpu cycles, if your other processes are not demanding them. If you saw the F@H process using 50%, then it means the other processes which have higher priority were only requesting the other 50%.

Some people are alarmed to see almost no cpu "available" while running F@H. This is how it is designed to run! You SHOULD see "no" cpu available when it is working properly. Available cpu is just wasted cycles.

As soon as a process kicks off that needs some cpu, the F@H process gets scaled back to a smaller chunk.

Then why does my machine behave better when I kill the folding @ home process?

I have to agree with Footeo on noticing a difference on my system when f@h starts up by itself. Footeo maybe load up Webmin and check what nice level it is running at when it starts.

I noticed it when I first set it up in that the backend seemed to be sluggish to respond when I was looking at say the Recorded Shows or even system status.

Whe I installed RRD and went through a restart it showed me the User CPU on that graph was about 95%. It would shift out of the way, some, but again everything was sluggish. I went into Webmin and looked at Running processes and f@h was about 90% or so. So I clicked on the Process number and it told me that f@h was using a nice of 0 (default) I reset it to 19 and applied. f@h still shows in the 90% range on Running processes but it steps back very well for other things like commflags etc. The rrd tool graph runs normally at 50% user and increases as myth takes off doing it's tasks for recording etc.

Amazingly the system is really snappy now, it is not uncommon for it to be running 2 commflags an a transcode at the same time as it is recording while a second recording is running on the Slave and it is transcoding something else. Typically at the same time as all of this the wife is probably watching one of her shows.

I am not saying f@h is bad, it just doesn't seem to be running at nice 19 when it starts after a reboot or something. Then it seems to really hog the sytem, if I set it to nice 19 then everything seems to play nicely.

Is there someplace I can look at the startup configuration to make sure it is being told to start at nice 19? is that in /etc/init.d ???

Thanks!

Try this...

Re-do the configuration of folding@home with the -config argument. When it asks if you want "advanced" options, say "yes". Notice when the process priority comes up -- mine is set to "idle" and it never, ever gets in the way of anything. Try it if it is not already set. Also read the choices carefully and avoid the ones that warn of large needs in memory or other resources.
