Once upon a time, for grins and giggles I'd look in here and see what my rank was compared to everyone else supporting LHC.
Either I've forgotten how I did that, or it's no longer on your menu. Can I get there from here? :)

Everyone else and I are fully aware of that option, thank you very much. It is kind of you to remind us all.
But not really helpful.

Maybe a viewpoint could be:
If the LHC devs don't want to support us peons (in the LHC programmers grand scheme), why should we spend our money, our compute time, our electricity charges -- supporting THEM?
Volunteers, spending real money, supporting a project that doesn't support US?
Is this where we are now?
I wonder just what percentage of LHC computer needs are solved by thousands of people spending so much time and money to further science.

All work will be accomplished from booting off a live USB.
Including making a backup image of the entire nvme drive, the only one running at the moment.

Found an entry in the very beginning of the log file.
/var/lib/boinc-client (I think it was.)

I shoulda put /var in a separate partition I guess. Still could and just put it on the new drive.

Post:
It runs just fine on a Jetson Nano. Haven't gotten around to testing the RPi yet. Sometimes, it only runs on a single CPU, sometimes on all 4. I'm guessing there aren't a lot of jobs for the ARM available. Right now, it's only doing one task.

Be advised, tasks take many hours to finish generally. But with the Nano only sucking down 10 watts, have no problem leaving it on 24/7/365. :)

computezrmle,

Yes, I try to speak in as high a level as I can when describing tech problems in order to ask questions with the fewest words. Yes, I am aware of most of the linux fs details but not all of course. I am aware of how to set up and mount new drives. :)

"Too much" = too much for me and I am concerned with the number of writes on an nvme drive. BOINC is obeying the limits I set but I had to increase them.


"BOINC uses a starting point called "working directory".
It's location can be found in the BOINC messages when you restart your client."
Where are those BOINC messages to which you refer? I've never seen them. I don't know what "restart your client" means, either. Do you, perhaps, start your BOINC inside the vm window?

"Parts of the BOINC working tree (that's everything below the working directory) can be mounted from other filesystems/devices."
How do I tell BOINC where that working tree IS?

Thanks.

Well, that is A solution but I was hoping for a better solution for this <censored><censored> high $ new system. It MUST serve more than one purpose. LHC ain't the only thing important in the world.

Posted 6 Apr 2020 by David E. Merchant
Post:
As long as long doubles, or at least long floats are used in the GPU, accuracy should still be equal to CPU runs, AIUI. We have the option (in the software) to truncate to 16 bits or even ints sometimes, as needed. Why would we use shorts or ints in scientific calcs?

I see various posts in here, that I don't understand fully, that imply people can look at the LHC config files on my local machine. Is this true? If so, then you can also browse my entire computer???

Post:
"The data for all the projects for 1 BOINC client has to be in one location, so it's not possible to separate LHC-data to another disk."

Ok, BUT, we can set a hardlink (at least in Linux/UNIX) TO that one location, right?

Is there a flag somewhere to tell the forum that if I reply to, or start, any thread that I want to be automatically subscribed to it, please? This would save grief on my (and probably others) part.

Thanks.

Posted 6 Apr 2020 by David E. Merchant
Post:
BOINC LHC is eating too much of my main drive. The new spinning disk should mount a a sub somewhere under root "/." Being a separate drive, will it still exist in the same filesystem so I can create a hardlink to it "from" the existing disk directory being used by BOINC?
1) Where IS that directory?
2) Is there a config file somewhere that lets BOINC know which directory I want it to work in? <--- This is the solution I'd rather use.
3) Is there a single directory for all BOINC LHC (and others?) tasks?

Thanks.

Post:
We actually NEED a separate executable? Shouldn't it be a loadable "module" at time of execution as needed? Even monolithic code would be better than loading the uses down with all this user overhead.

Good catch on cpu-virt. Somehow, it got disabled in the past week or so. All the BIOS work was finished by then. Maybe UEFI changed it without my knowledge or something, not sure. I noticed a couple other flags modified while setting up the BIOS and it's tweaks.

Posted 6 Apr 2020 by David E. Merchant
Post:
Dang. That is illogical. If that's how the UI guys interpret this, then there needs to be TWO flags for this: 1 for allow native, and a second for allow vbox work. And just why are those two types of tasks separate anyway? No one needs to fool with all those flags. Have the executable work on all, regardless.

I set all preference boxes to what seemed the most liberal. Now you're saying the user interface requires me to NO allow different kinds of tasks in order to get available tasks? What's wrong with this picture?

Loaded vbox. After several comm restarts, boinc-manager loaded many Theory 300 tasks and every single one throws a comutation error almost immediately upon task start.
Have no clue where the problem lies.
