1) Message boards : Questions and problems : headless raspberry pi (Message 104540)
Posted 10 days ago by MarkJ
Post:
Hi,

I have a few headless raspberry pi4's but do not see an option to install and configure a min setup on the CL. anybody have experience with this?

Basically install Raspberry Pi OS - the "lite" version on your SD card. You'll need to enable ssh so you can login to the Pi seeing as its headless. Once you've got the Pi booted you ssh into it and do everything from the ssh session (eg OS updates, install BOINC, edit config files).

They are much easier to manage if you set BOINC up to allow remote control and then you can use BOINCtasks to do the usual things you would have done via BOINC Manager. Its also great at displaying a "farm" wide view of what is running. I have 12 Pis all headless running BOINC 24/7.

There has been some progress. Latest news says:
Server status update
BOINC server is now running but it is still a temporary solution and there is still some additional work that needs to be done. New workunits should be available in a week or two.

The server status page is showing the upload and download servers as being active. Scheduler requests return "Project is shut down for maintenance". Give it some more time for things to return to normal.

I usually do a chown boinc:boinc on the two BOINC folders (/etc/boinc-client and /var/lib/boinc-client) and don't seem to have issues. For the manager I added a desktop shortcut but modify it to add --passwd xxx to its command line so it can connect. This is under Debian buster using the repo version of BOINC with the Mate desktop.

Post:
What GPU (or GPUs) do you have in the machine? Please post your BOINC startup messages for the GPU detection and advise what kernel version you are running.

I suspect you've been caught by the "GPL condom" as the kernel developers called it.

From their home page:
I am sorry for the current problems, unfortunately the database server crashed - hardware failure. I can't say now when it will be running again. I will post any news I'll have.

I expect they’ll be offline for a week at least, maybe longer.

Post:
So doesn't look like the app is using the second FP32 pipeline. So responding like previous generations. Typically not exactly double the crunch times. So the card might be slightly more productive doing doubles compared to singles at the expense of using a lot more power.

Maybe it needs to be recompiled with the latest CUDA toolkit to take advantage of the additional pipeline. CUDA 11.1 was just released with support for RXT30 series cards. Phoronix article here
7) Message boards : BOINC client : Authentication error (Message 100675)

Post:
Normally you have to also supply the password (the one in /etc/boinc-client/gui_rpc_auth.cfg) so try this (substituting the password).
boinccmd --passwd PASSWORD --project_attach http://www.worldcommunitygrid.org (my-key)

I installed Boinc to run Einstein. It put some files in a directory I keep clean of such files. I want Boinc to work. Can I move them to a folder, such as /usr without having to remove/re-install or otherwise work with this? I would like to create a folder in /usr with the name: boinc and put them there. Will this interfere with normal operations?

You haven't said where you got this version from or which flavor of Linux you are using.

If you installed the T-Bar all in one version then it puts all the files into your home folder. The official versions that come from the Linux repos do not. Most repo versions will put their files in /etc/boinc-client and /var/lib/boinc-client (or /var/lib/boinc).

A bit off topic. Thanks for the links Richard. Perhaps we could have a section or message board with links to the project calls and their files rather than relying on someone's google drive. If we could put them in one place. The BOINC project server would seem to be a logical choice.

Maybe we could replicate them on say Radio BOINC Network, if they are willing to host them (I haven't asked them). I figure people will be on there to listed about BOINC anyway so might be interested in what is going on.
10) Message boards : Questions and problems : nVidia not detected on MXLinux (Debian) (Message 100260)

Post:
Have a Latitude E6420 notebook with an NVS4200M chipset (Optimus) with current MXLinux.

I installed the 390 legacy drivers then installed BOINC. Both are from Stable. The GPU wasn't detected.
<snip>
I tried restarting BOINC and rebooting to no effect. I can't seem to find anything on my searches to resolve this especially since a lot info is several

Under Debian I install nvidia-driver and nvidia-kernel-dkms. If you want OpenCL you’ll also need nvidia-opencl-icd. You’ll have to reboot after installing them.

Given it’s an old GPU you might be out of luck with CUDA support.

Post:
But some GPU projects require CUDA drivers, not just OpenCL. If you have a problem with getting work from a project you know supports NVidia cards under Windows, you may need to download a new driver direct from nvidia.com

His cards are listed as AMD Radeon so he won’t be doing any CUDA work.

It should say Config: Use all GPU’s in the log if it found it.

Post:
It doesn’t say it’s using all GPU’s so it didn’t like it. Recheck each point Jord has mentioned.

Also current version of BOINC for Windows is 7.16.7 I would upgrade to the latest version otherwise you might have issues connecting to certain projects.

14) Message boards : Questions and problems : Second manager window. (Message 99274)
Posted 13 Jun 2020 by MarkJ
Post:
When I try to connect a second manager window to my second computer, it asks for the machines name and password. Completing these results gives me "The password you have provided is incorrect, please try again.". I have just logged into that machine, and am sure, the name and password used are correct. Both machines are connected to ports on the same router. Both run Windows 8.1 x64. What is going wrong here?

It’s not your Windows (or Linux) password. It’s the one in gui_rpc_auth.cfg which is in your BOINC data directory.
15) Message boards : Questions and problems : Peer certificate cannot be authenticated with given CA certificates (Message 99187)
Posted 9 Jun 2020 by MarkJ
Post:
Yesterday (Mon 8th of June) Debian issued an updated ca-certificates. They added 13 and deleted 15, although it doesn't say which ones. I wouldn't be surprised if this has caught a number of organizations out, not just BOINC. I can still communicate with all my projects so they don't seem to have broken anything as far as I can tell.
16) Message boards : Questions and problems : BOINC Manager won't come up in Linux Mint (Message 99150)
Posted 6 Jun 2020 by MarkJ
Post:
Been running BOINC for years, been running it on Linux Mint for >1 year and now I can't get it to bring up the Manager. Tried restarting, tried a couple of simple command line things (sudo service boinc-client restart), quick searched the message boards.

I'm no pro at Linux; anyone have any advice for what to try next?

There was a similar message from David Pickett. He ran a strace on it and it would look like there is a desktop file that might be causing the issue. See this message

That suggests that in your home folder there will be a file called BOINC Manager-xxx that probably stores information about where to position it on your desktop.
17) Message boards : Questions and problems : remaining time to next checkpoint (Message 98956)
Posted 31 May 2020 by MarkJ
Post:
BoincTasks (a replacement for Boinc Manager) has this option. It also can show how long a go a task did a checkpoint and how many checkpoints it has made. But it won't show when next is due.

If you have checkpoints displayed in BT on the tasks tab, it highlights tasks that have exceeded the checkpoint interval in red.
18) Message boards : BOINC client : Why not use whole numbers instead of % for multiprocessor usage? (Message 98951)
Posted 31 May 2020 by MarkJ
Post:
Perhaps a better suggestion. It could have a slider with 0 to 100%. As you slide it display the percentage above the slider and the number of cores out of the total available underneath. You don’t need to change the core client to implement it, it’s a GUI change.

I believe there was mention of a developer looking at the GUI with a view to updating it.
19) Message boards : Questions and problems : Running the client on a different machine than the computation (Message 98883)
Posted 29 May 2020 by MarkJ
Post:
I am currently in the process of researching the possibility of running multiple machines that run BOINC computations and only having one central computer that is interfacing with BOINC servers. For this I assume I would have to modify the client so that the logic for execution is separate from the one managing tasks.

It does support use of a proxy server if you want a separate machine to communicate with the outside world, but it sounds like you were after more than that.

Moot point though. I found a post from myself to someone inquiring on how to get an ARM64 device to get work from the project. My own response said there are no applications for any active projects. The only applications that were available for ARM64 are for the deprecated Neutron Star and Black Hole formation project.

Rosetta have an ARM64 app if you want to use it over there.
