The Linux Help and Tutorial Thread

[PoppaGeek]

I'd have to look it up but all the reporting stuff in Solaris is available in the Linux version of top, you just need to use the right flags ... which I don't remember. I'm sure you can configure top's default to show whatever you want, but again I don't remember the syntax etc. man top is your friend.

Linux top man page does not explain several things. Found some here.

I did use top on Solaris but Solaris has many tools for monitoring system hardware and software. Some if not most have probably been ported to Linux by now but I need to do some searching first.

@OC. I did use the cc_config.xml and nice value dropped from 19 to 10 but us shows 0.0% and nice shows 95-99%.

Jim, Command line is the easiest way I know Poppa posted at start of his update linux thread or there is the D_A post on the using Linux thread

http://www.xtremesystems.org/forums/...ely-site-Linux

http://www.xtremesystems.org/forums/...=1#post5024891

whichever you like.

hard to tell if any improvement due to change to MCM1

Poppa, edit to my previous too

Thanks OC and PG for the info.

OC, I don't know if its just this one WU, but I just saw one of my first MCM1 WU's take 2hrs and 42 min past the estimated time to complete(total time to complete was 7hrs 2 minutes). I'll be watching the MCM1 WU's tonight to see if this reoccurs. So far I think I've only completed MCM1 WU's on one rig so I don't know if its rig dependent, WU dependent and/or Linux dependent.

Took me awhile to remember then find it but here is a package of utilities to monitor the system. Nothing friendly about these utilities. But very powerful. Depends how far down the rabbit hole ya want to go. It is deep......

sysstat docs and tutorial. You can write to a file and use isag to plot graphs from the datafile.

sudo apt-get install sysstat isag

I should add both top and sysstat get their info from /dev/proc which is where the kernel accounting is written. So you will be getting info from the same place just with stsstat you can configure it to get data over time as well as more specific data.

I think Dave just bailed on this discussion!

Some incredibly powerful tools available in Linux, lots of stuff ported in from Solaris, BSD, System V etc, but the user is expected to step up with the power tools not the other way around. They're not for newbies.

[PoppaGeek]

Dave? In this thread? You messing with me right?

I get why people want to use Mint. It's fine but if you want to squeeze the absolute most from your system install Ubuntu server. No X, no GUI. I don't know how many times D_A has said it but X does use some CPU. I run 2 crunchers on Ubuntu server. I see 99.65 and 99.99 in BoincTasks and 99-100 in top.Uses less memory and disk space too. With Boinctui you can use a monitor. I run headless and use ssh.

I thought Dave married Bill Gates daughter or cousin? No? Just bros I guess.

I don't recall saying I was pretty

[OldChap]

The comfort of the GUI is worth the small percentage to us stubblies

I just took a fresh look at all 3 rig's results for the last 100 results with the single cpu rig, now running 16 threads, biased to 50% of the results.

I see cpu time of 429.91 and real time of 430.68 or 0.77 of an hour in about 430 hours (~46 mins in 25800 mins) so losing 1 min every 560 mins

In my book that is good enough and seems to show that allowing the scheduler to do the scheduling is no bad thing..... at least on a dedicated cruncher.

[PoppaGeek]

I don't recall saying I was pretty

It's ok your boyish figure and youthful vigor makes up for it.



My boyish figure and anything to do with vigor is a distant memory, and with dementia there ain't much of that either....

Being pretty is all I have.

Poppa,

I'm not sure that any photos of me even exist. I shall have to get the camera out.

You WILL be disappointed.

hmm that is interesting. Tell me do you see anything when you look in a mirror?

[D_A]

OMG that's funny.

But at least now I know that I didn't change distros enough.

I find it interesting that Linux users are assumed to be able to produce their own CPUs from scrap silicon that run on light from Saturn. I'd at least need some fencing wire, duct tape and maybe a few cable ties to sling that lot together.

[PoppaGeek]

Your lesson for today.

[PoppaGeek]

A rather powerful program for managing files on a Linux system that has been around a long time is Midnight Commander. Between it and Boinctui they would make a Ubuntu Server pretty easy to manage.

sudo apt-get install mc

[Evantaur]

why not apt-get install wife --no-install-recommends

[D_A]

why not apt-get install wife --no-install-recommends

Because that doesn't stop dependencies, just the recommended extra packages.

Today


His name, Igor.
Uses command line since age 3.
His beard grew over nite.
When he walks the barren tundra of Siberia
female polar bears offer themselves to him.
Male polar bears offer him meat from their kills.
Wolves sing ballads of his shell scripting skills.
The ground quakes and vibrates at the sound of his voice.
The clouds clear when he looks skyward.
No human has ever looked him in the eyes. And lived.
Windows users flee his presence, Mac users faint.
He is Igor. He uses the command line. Fear him.

I spent several hours trying to get backports working on Mint the other night using the graphic package managers. Could not get either to show me anything but the one boinc 7.0.27. I know there is a 7.0.65 in the backports for Precise and I am sure someone else can get it to work. I couldn't.

This a.m. I spent maybe 20 minutes, mostly reading and squinting, bad morning, but got what I wanted using only the command line.


First determine which release of Ubuntu or Mint you are running.


NOTE: I am using precise so you will need to replace precise with the version of Ubuntu you are running.

To find from command line in Ubuntu:

poppageek@A8356srv:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 12.04.3 LTS
Release: 12.04
Codename: precise

If you are running Mint you are still running a version of Ubuntu.

Mint 15 is raring
Mint 14 is quantal
Mint 13 is precise

If you run lsb_release in MInt you will get the Mint release name. For Mint 15 you will see Olivia. Olivia is Ubuntu raring. So use raring-backports. http://www.linuxmint.com/oldreleases.php Use to convert Mint versions to Ubuntu.

================================================== ================================================== =======

So for my Ubuntu server 12.04.3 LTS I added

deb http://archive.ubuntu.com/ubuntu precise-backports main restricted universe multiverse

to /etc/apt/source.list

To install from backports.

sudo apt-get install boinc-client/precise-backports

Installs 7.0.65+dfsg-3~ubuntu12.04.1 from backports.

See next post for condensed instructions on adding line to /etc/apt/source.list

[PoppaGeek]

Installing backport versions of boinc-client Condensed to only instructions: Read previous post to determine which version you have. Mine is precise.

Backup up config file:

sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup

Edit /etc/apt/source.list

Add to bottom of file

deb http://archive.ubuntu.com/ubuntu precise-backports main restricted universe multiverse

REPLACE precise with the codename of the version of Ubuntu you are using. Above post for info on Mint codenames.

To see current backport version of boinc-client

sudo apt-cache show boinc-client/precise-backports

To install current backport version

sudo apt-get install boinc-client/precise-backports

================================================== ==

Another way to append the line to /etc/apt/source.list

change precise-backports to your version. Backup file first.

sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup

Then add line to /etc/apt/source.list

echo -e "deb http://archive.ubuntu.com/ubuntu precise-backports main restricted universe multiverse" >> /etc/apt/sources.list

It is a good idea to backup config files before editing them. It is REAL easy to mistype something.
