Like Richard said, 0.9 doesnt mean it’s using that much. That value is only used for the BOINC internal book keeping so it knows how much resources are being used and how many jobs to run.

With gravity wave, I actually observed the GPU tasks using more than a full thread. About 1.2 - 1.5 CPU threads per GPU WU.

It's relatively unimportant for SETI-only crunchers, and for users of BOINC v7.14.2

But be aware that there's a change coming in BOINC v7.16.n - all those 0.9 CPUs for GPU tasks will be counted up and used to calculate how much cache time you have left for CPU tasks. CPU caching for other projects may be adversely affected if you have a lot of GPU tasks lined up. Work fetch for CPU can be restored to normal by setting a lower value via app_config.xml

Use the jonasmalacofilho liquidctl application instead. Much easier to install and get running. I had no luck with the OpenCorsairLink program. Probably only works on Corsair hardware. The liquidctl application works on most of the generic Asetek AIO hardware coolers.

On the subject of pictures - it would be helpful if you could use an image hosting service which would allow you to show screenshots at a higher resolution than 300x240 - I found those hard to read.

I am not sure what the resolution is on the original screen shots. I did manage to get some shots of E@H during the maintenance on Tuesday. Does anyone recommend a website for hosting images? I know it is an issue with Google drive, you have tickle it just right. And my other choice of a host is my free Blog site from WordPress.

Thank you Ian.





I hope I didn't screw it up again.

. . You could try DropBox if like.

Yeah it’s because each CPU task is using a massive amount of memory. 750MB for each instance.

So you will have to limit the jobs as you’ve done and use the CPU less, or if you want to use more threads, you need to add more memory to the system.

For image hosting I like imgur.com best.

@ Jimbocous

An update to your instructions:

I just wasted this morning trying to re-install Ubuntu and BOINC. Finally, I got it to work, but ...

If you update the Ubuntu system after installing and before following these instructions, your
instructions fail. If you DON'T update after installing, your instructions work beautifully.

It appears to this neophyte that some security update has broken something needed, since
I ONLY updated with security fixes. Perhaps a Linux guru can tell me what it is/was.

So if you are pounding your head against the wall trying to make this work, stop, re-install
Ubuntu but DO NOT UPDATE YET, and follow these instructions.

I'm a tad puzzled, in that I really wasn't trying to do a full install instruction here, if I'm understanding which message you're replying to, but rather exceprting from TBar's full instructions out of his AIO package just the parts for adding OpenCL.
Or am I missing something here? Can't tell without some quoted context.
[edit] Ah, I see, that was from a month ago. Sorry, recycled those brain cells a while back. But that's what I get for just excerpting. Ian&Steve covered it more thoroughly in the next message.

@ Jimbocous AND Ian&Steve

I think your instructions AND Ian's are equivalent, and WON'T work if a new install
of Ubuntu is done AND then had the system security updates applied before doing the instructions.

Your instructions:
==========================================================================================
10) Add this to your system so you will be able to easily install the Video drivers:

|sudo add-apt-repository ppa:graphics-drivers/ppa
|sudo apt-get update

11) Install NVidia and OpenCL drivers:
|sudo apt install nvidia-driver-430 ; needs repository in #10 installed or fails
|sudo apt install ocl-icd-libopencl1 ; changed from sudo apt install libopencl1 fail
then Reboot
12) Use the "software updater" to install "additional drivers" and upgrade Linux/Ubuntu to the latest driver (probably).
==========================================================================================

Ian's

==========================================================================================
sudo apt remove boinc-client
sudo apt remove boinc-manager

first add the Ubuntu drivers PPA.
sudo add-apt-repository ppa:graphics-drivers/ppa

update repositories:
sudo apt update

install the driver:
sudo apt install nvidia-driver-440

install the openCL driver for AstroPulse tasks:
sudo apt install ocl-icd-libopencl1

Then reboot. you should be done and ready to go.
==========================================================================================

Your instructions worked about December 10 or 11, but now they don't -- UNLESS I don't apply system security updates
before using them. My deduction is that some system security update BROKE something here.

However, I had installed the BOINC Manager/client from Berkeley before December 10, but not now. I did NOT remove them
and things worked as far as BOINC was concerned. I did not get WSDD or Network Neighborhood working, which is why
I did a clean install, etc., trying to "fix" whatever I had broken in that function.

I don't know enough to further diagnose this, only enough to report it for someone more knowledgeable to go after it. If
someone wants to chase it and wants my help, PM me to avoid confusion here, and we will report any fix found.

I'm a tad puzzled, in that I really wasn't trying to do a full install instruction here, if I'm understanding which message you're replying to, but rather exceprting from TBar's full instructions out of his AIO package just the parts for adding OpenCL.

. . A good place to say thanks for that help BTW. Fixed the OpenCL problem and Einstein then worked fine.

Stephen

HOW does it not work?

Which step does it fail and what is the error that is spit out?

Need to some more details if we’re to help.

What distro and version of Linux are you trying to install? If you are installing the latest Ubuntu 19.10 version, installing drivers manually or adding the ppa is unnecessary because the Nvidia drivers are included already. Only the OpenCL parts might be missing.

@ Ian&Steve C.
It doesn't work if I apply security updates immediately after installing Ubuntu 18.04.3. This is
how I have installed new O/Ses for years, but it is wrong here.

Install Ubuntu but DO NOT UPDATE before doing the steps AS WRITTEN works.

I no longer need help with this as I have it working now.

Thanks Ian.

@ Keith Myers

What distro and version of Linux are you trying to install?

It is Ubuntu 18.04.3, and it does work IF T-bar's instructions are followed TO THE LETTER.

Thanks.

Again. Please be more specific on exactly HOW it doesn’t work if you do updates. What exactly happens?

I’ve updated my systems and it still works fine.

Seti@Home classic workunits: 29,492 CPU time: 134,419 hours

I was looking at my task manager on my 3950x Linux box.

And while it is not running S@H tasks right now it is showing a 2/3rds 3% cpu load to 1/3rd 2% cpu load on the World Community Grid cpu tasks I am running.

I am not certain I am seeing any differences in processing time but has gotten me to wondering. I run 90% of available cpus on BOINC. And the over-all work load reported is at around 88%-91% just like it "normally" is.

I have a raft of E@H cpu tasks parked waiting since I turned WCG back on.

Any discussion?

I have run on Windows for almost 20 years and I am finally setting up a dedicated Linux box. I have had a lot of help from Keith Myers from the GPU users group to get things running. I will be starting with CUDA90 but will hopefully step up to CUDA102 quickly. It is a new rig, I went all out on the processor (Threadripper 3970) and added dual RTX super 2070 cards. My RAC has been pretty sad as of late.

---

I saw your post over on the Lunatics installer thread. Make sure to use Richard's latest installer for the Windows side of the rig. If you use the latest Nvidia 442.19 drivers, you can avoid the issue of the stalled out VHAR tasks from the Arecibo antenna. The SoG app is fastest and safe to use with the latest drivers.

For the Linux side, TBar's AIO is the easiest and best to use. Start with the default CUDA90 app. Update your drivers to the latest 440 series using the graphics-drivers ppa repository and after rebooting, edit the app_info with Find and Replace in the Text Editor to switch over to the CUDA102 application.
