[librin.so.1]

Installed again with HPET disabled. boinc is working right now and so far has completed 8 tasks. Normally I'd report them manually but I don't want to disturb this install at the moment.

Do You also pass the hpet=disabled option to the kernel? As Linux often disregards most of the stuff set in the BIOS and just enables / disables stuff it wants. (it sometimes even enables some things that the BIOS doesn't support, heh)

 

[TRWOV]

How do I add that command?


Also, how can I disable sleep? I got home and found the cruncher sleeping but couldn't wake it up. At least it survived the hard reset, a good sign IMO.

I checked in Power Manager but it only has settings for spinning down disks and turning off the screen.

edit: I'll try disabling it in the bios.

 

[librin.so.1]

As root, edit the /etc/default/grub file. Find thes line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

Make that line into:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash hpet=disabled"

Then, run this:

sudo update-grub2

Reboot. Now, each time You boot the kernel will have that option set to disable hpet.

To disable sleep, open the "Power Management" app. If You want it to not lock / blank out the screen, You can disable those in the "Screensaver" app.

 

[TRWOV]

I think that the cruncher is going into sleep even with all the cores loaded.

When I lost the remote connection with Lubuntu I came back and found a blank screen. The first time with mint was the same. Now it's doing it again but at least it didn't die now (maybe the hpet thingy worked).

I'll disable all sleep states in the bios but is there a way to disable it in the OS?

Read the bottom part of my previous post.
P.S. that whole previous post was for You, TRWOV.

 

[TRWOV]

Sorry, you ninjaed me

 

[Peter1986C]

I suppose that if I make a kernel image by compiling a kernel in Gentoo, it should also work in other distros as long as we refer to it in the boot loader properly (beside putting it in /boot), right?
I could make one with HPET disabled by default and only the performance governor in use, if you wish.

 

[librin.so.1]

Hold on a sec... Lubuntu? Ah right, it might have different kind of power management apps. But if You did not find the sleep option in the Power Management app (which in my case has it in the very first line, right above the HDD sleep option), then look in the screensaver settings app. It might be slapped there for some reason. But yeah, it varies.

 

[Peter1986C]

Last time I looked Lubuntu used the cpufreq deamon, like most or all distros. Disabling it under power management and under "screen saver should do the job although I could try and make a custom kernel after that.

 

[TRWOV]

I'm using Mint now.

 

[Peter1986C]

The Cinnamon desktop should be similar in where the apps for setting PM are put, as well use the same daemons for the PM.

Edit: are you on 64-bit?

 

[TRWOV]

I think I'll keep the 880GMs after all. I've found out that the only reason for the board to run the Visheras at 2.8Ghz is because it doesn't have official support but if you set the multiplier manually they can run them. Aparently the VRMs are rated for 140w TDP so handling the 8350 should be no problem. I just hope Gigabyte comes out with an updated bios soon.

I don't like mint or cinnamon. I prefer fruity flavors

 

[laptop-hpc]

I'm using whatever Mint had preloaded/downloaded. Graphics are HD3200 IGP.

I remember reading somewhere about HD 3200s rarely causing random lockups/crashes, with
both the open and closed linux drivers, though I can't think why that would mess up the
filesystem.

If the IGP is the problem then maybe disabling desktop compositing, or running the VESA
software driver ('nomodeset' on the kernel line, iirc) would help.

 

[TRWOV]

oddly desktop composite is disabled by default. The installs are surviving so far, no damaged file systems but the graphics driver is crashing at random.

Question: if the driver crashes do applications keep going or not? I suppose I could live with headless crunchers, or should I relent and get a cheap card or something? What's a good card for Mint? I have a couple of X600 laying around that I could use, are they fine?

The X600s might be even worse since they are ancient compared to the 880G. Proprietary drivers are kind of sucky ducky on Linux because the kernel is always being changed, and when manufacturers stop updating drivers, good luck getting proprietary drivers working with newer distros.

 

[TRWOV]

So a 5450 then?

 

[Jstn7477]

Yep, should work. Give it a go and see if it is any improvement.

 

[librin.so.1]

This kills off the X server, so the answer:
All the GUI apps and all the apps started from the GUI will die. BOINC is started as a daemon before the GUI even initializes, so it should stay fine.

I suppose I could live with headless crunchers

I run a headless cruncher, so have some experience with it. If You need help setting one up and managing it, don't hesitate to ask me

 

[laptop-hpc]

Question: if the driver crashes do applications keep going or not?

That depends: If the driver crashes *cleanly* then any system/console processes should
continue unharmed, but I have had plenty of GPU lockups that seriously mess with the kernel,
or something, and totally lock up the system (keyboard lights don't work, black screen, USB ports
don't work/provide power, network cards shut off, all at the same time ).

I have a couple of X600 laying around that I could use, are they fine?

They should be fine on the open r300g (stock radeon) driver, I run a Radeon 200M (in my Turion cruncher) with r300g,
and haven't had any issues with stability in the last few years.
The 200M is the same r300 core as the X600s, so I don't see why they would have problems.

That's my experience anyway.

and totally lock up the system (keyboard lights don't work, black screen, USB ports

I noticed that 95% of the time such apparent "complete" lockups happen, the network and the SSH Daemon still magically works and thus it is possible to SSH into the system and bring it back up.

Let me know if you want me to jump on it--I'm usually up when they come out

My 2600k system is doing amazingly--running just DSFL it's pulling just shy of 9k PPD. With just FAAH it would do just over 6k PPD. Linux is amazing

Are you just limiting your rig to this project, or is there some added benefit from running this project on Linux?

All CPU WUs simply work faster on Linux. That's all.
Hence Linux being the best for CPU crunchers.

For example, an overclocked i7 hex-core can easily go over 10-12k ppd on Linux.... which is up to a 50% improvement

That said- I'll be moving at least 1-2 of my rigs over to Linux over the next few weeks

is there a reason for this? that it runs better on Linux?
