[gentoo-user] Screen is being a CPU hog, big time!!!

Hi all, it is me again.  LOL

I run folding on all my rigs and noticed something strange.  It uses
screen so I can detach, logout and etc.  Check this out though:

Now so you will know, this rig has a AMD 2500+ CPU.  This is not one of
my very slow rigs.  Why is screen taking up so much CPU time?  Almost
45%.  O_O

What I have done so far, re-emerged screen and done a etc-update, almost
hit the tab key after etc-.  :/  Habit I guess.  LOL  I did a env-update
and even logged out and back in.  Nothing but more smoke.

What is up with this?  It was working fine the other day.  I have gotten
to where I use it a lot.  I'm still trying to figure out screen but I am
making progress with it.  This is what it looks like on my AMD 800 MHz rig:

Do I need to back up a version and mask it for a while?  If so, how do I
get the previous version info?  I assume it is equery something.  I know
how to emerge it I think but they changed how to get a list of what
versions are in portage since I used it last time.

Thanks, I hope someone knows how to fix this.  I may copy my config file
from one of my other rigs and try it.  Sort of chicken though.

My lady is supposed to call, so I will check in when I can.  Dial-up
user here.

OK, it is in the config file somewhere.  I renamed the old config
screenrc.old and then copied the config file from another rig, it works
fine now:

That is how it should be.  I do want to figue out that config thing
though.  It may cause something else to mess up that I don't know about,
yet.

Thanks again for the help.  I'm clueless but I'm looking.

Disregard all that.  I was logged into one of my old rigs via ssh and didn't notice it.  That was the old rig that runs correctly.  It is still using a lot of CPU time even with the older config file.  May be something else after all.  At least we eliminated that though.

I need help.  I have to many rigs to keep up with.  o_O

Any ideas?  Thanks.

Re: [gentoo-user] Screen is being a CPU hog, big time!!!

OK, as a bit of a update.  I started a screen session and then emerged
mozilla inside that session.  It worked fine that way.  There is
something wrong with the way folding is using screen I guess.  So I did
a bit more digging here.  I found this command in one of the startup
scripts:

>add_pref="screen -dmS FAH1"
>
I looked at the man page, they are listed but I have no clue what the
heck they do, even though I RTFM.  Does anybody here see something wrong
with these options?  Maybe have some better options that I can use?

I had to stop my folding so I really need to beat this into shape.

Thanks,

Dale

Looks alright, fairly standard options. 
  -d -m (same as -dm) implies starts a new screen detached
  -S FAH1 says that screen session will be named FAH1, so you can
     reattach the session via 'screen -r FAH1'

It is probably something else that is causing you trouble.

You're right, it is something else.  I used the command with something
beside folding and it works just fine.  I have no clue what to do with
this thing. 

I also searched the emerge log, screen has not been updated.

I may delete the folding directory and just start with a fresh install. 
I use finstall to do my folding.  Funny thing is, I have not done
anything to folding except stop start when I need to reboot or
something.  Other than that, it just runs.  It works fine on my other
rigs as well.  I use the same version of screen and used finstall on
them too.

If anybody has any ideas, I need them.  I did just download a new
folding thing so I am not really loosing anything but it will make them
think I'm working on it when I am not.

Thanks for any help you can give.

Sorry if you might have explained this before, but can you refresh my

Well, I didn't but I thought most everybody had heard of it. 

http://folding.stanford.edu/

It is a medical research thing that people run on their rigs.  It is
very CPU intensive too.  If you think you have a cooling issue with your
CPU, run folding for a while, it will find it.

No clue yet why it is doing this.  I may post it on the folding forums
and see if anybody else if having this problem.

Thanks,

Ummmm is it possible that the screen cpu usage is reflecting the CPU
usage of folding (which is running within a screen session if I read
you posts properly)

perhaps try running some other cpu intensive task within screen and see
what happens?

The OP mentioned he tried compiling mozilla inside of screen. And the
CPU usage was normal for screen. So I don't think this possibility is
likely.

Oh... the protein folding thing. Since you run it in screen, I assume
you are running the text-mode client? Just out of curiousity, on the
two boxes you have, did you run the same version of the client? 

I just downloaded the stable version (FAH502-Linux.exe) and have been
running it in screen for the last hour or so. So far I cannot see the
same behaviour you are describing. One thing I noticed, for some
reason the one I am running is loading FahCore_82, while yours load
78.... 

Anyway, did you install foldingathome through portage? What is the
command you are using to start the process? 

Try downloading the client directly from the Stanford website, put it
in a new directory, cd to that directory, and issue
  screen ./FAH502-Linux.exe
and see if the problem persists.

I tried that and it worked fine.  I started a screen session and emerged
mozilla.  The merge stuff showed heavy CPU usage but screen only showed
<1 or 2%, like it should.

I really think this has something to do with folding itself somehow. 
Screen is actually taking up the CPU time though.  Folding is really
slow when it does this, real slow.

Thanks

Well I used finstall.  The reason I did that is because of my quad CPU
Compaq server.  With finstall, it handles all 4 CPUs and the same time
and with one command to start or stop.  It is a really nice way to do
it.  I like consistancy so I installed it on all my rigs.  I also fell
in love with the screen thing as well.  Funny huh?  LOL

I posted a thread on the folding forums.  If no one replies before to
long, I'm going to delete and start over with a fresh install.  Maybe I
got a bug or something.  Knowing me, I just screwed up something.  LOL 
It happens, especially with me.  :(  The best thing that has happened to
me in a very long time is finding my new lady, after 15 years of looking
I might add.

Thanks

Well, the folks on the forums couldn't figure it out either.  I deleted
the folding stuff and re-installed it.  It works fine now.  I guess it
had a bug in it's butt or something.

Strange though.
