Not sure what your response means. The command itself does not produce any output to the terminal. All it is doing is adding your username to the Boinc group so that you, the local user has permission rights to the Boinc directories.

You can check to see that you are now in the boinc group by executing
groups
in the Terminal. That will produce output of which groups your local user belongs to.

Did you perform the rest of the instructions in the Linux help page. Specifically, did you enable Boinc to be run automatically at startup?
https://boinc.berkeley.edu/wiki/Installing_BOINC_on_Debian_or_Ubuntu

Does Boinc now run? Does the Manager now connect to the running client?

Yes, that version of the application package is broken.

You should read the instructions for Linux here:
https://boinc.berkeley.edu/download.php
https://boinc.berkeley.edu/wiki/Installing_on_Linux

You must execute this command from the instructions in the Terminal:
sudo usermod -aG boinc your_username_here

You should report this to the Debian Bookworm BOINC distro maintainers.
Also log a issue at BOINC Github.
https://github.com/BOINC/boinc
Possibly a problem with the WxWidgets the Manager was built with by the maintainers.
You should also try this new Dark Mode Manager. It is the latest build by the devs.
Manager version 7.23.0
WxWidgets version 3.2.2

Actually I was extremely surprised that the recent Dark Mode Manager artifact had control over the client reinstalled. One main reason I have stuck with an older Manager was the ability to start and stop the client.

I really hated all the latest distro supplied Managers having that control removed.

The ICD file can be incorrectly linked when the distro installs the basic AMD Mesa drivers and ICD for that set of drivers is pointed to. Seen that error a lot on posts in the forum for AMD cards. The ROCm drivers put the ICD file in a different location I believe if I remember correctly. Hence the conflict.

You might try power limiting the card to test for stability. Could simply be the memory or processor is running too hot and crashes out.

Please read this message for some hints about getting the 7900XTX working.
https://boinc.berkeley.edu/forum_thread.php?id=14916&postid=111107
Also check that the /etc/OpenCL/vendors file is pointing to the correct opencl library probably in /usr/lib/x86_64-linux-gnu
I've read that the vendors list points to the wrong location often for the correct opencl library.

Post:
The scheduler reply looks like it is requesting work for the cpu and Apple M1. Not familiar with Mac M1 but I suspect the Apple M1 identifier is referencing the igpu on the chip.

If this is the case and supported by the identification of Apple M1 in the OpenCL detection, then the reason you got no work from the Milkyway project at least is that project has discontinued support for all gpus. Only cpus supported now.

I don't know if Rosetta has a Mac M1 gpu application or if it was just out of work. Milkyway does not support the Mac M1 for cpu applications.

The legacy AMD drivers for the older series seem to be mostly stable once you get past the arcane installation of OpenCL.

The newest architectures are just not ready for primetime for compute. Maybe in a year or so things will have gotten better.

Consumer AMD cards are generally a poor choice for compute. They are meant to be used in gaming only. The drivers are woefully inadequate, poorly developed and of not much importance for the developer to debug or properly design the consumer drivers for compute.

Only the professional AMD compute cards should be used for compute. The drivers for those cards are actively developed, the opposite of the consumer drivers.

You would have better luck running the latest beta drivers from the github sources.

Not sure why you installed the Nvidia drivers in your previous attempt when you don't have an Nvidia card. Your video drivers need to be by AMD.

Redo your group addition from your previous attempt. Should clear the Manager connecting to the client issue.

Post:
You might find setting your checkpoint interval in global_prefs_override.xml will work better that using that set in global_prefs.xml , the latter can be written/over written by projects, while the former is under your control.

If you read his OP, you can see that he has already set his checkpoint interval to 60 seconds.

Unfortunately, a majority of projects ignore this value and let their science applications determine when to checkpoint. Many cpu apps don't checkpoint at all. Even a lot of gpu apps don't checkpoint. With gpu tasks though, the penalty is less because of their short runtimes. Starting from scratch isn't as hurtful as losing all progress on a multi-hour or multi-day cpu task.

HI

Added the following to the global_prefs.xml settings:
<disk_interval>60</disk_interval>

However, many projects seem to ignore checkpoints.

I'm looking for a project that respects checkpoints.

I'm using linux.

best regards.

Depends on the science application mostly. Not the project per se.

What kind of tasks are you interested in? CPU or GPU? Or both?

Post:
The reason that servers lead the stats is simply because of scale. They have far more cores than even the best mini-PC. Hundreds of cores vs 8-16 in the mini-PCs.

Plus the servers are able to use multiple gpus which are more productive than cpu cores. But the cost efficiency is still probably in the favor of the mini-PC because server hardware, memory and multiple gpus cost 10X- 100X more than the typical mini-PC. They also use far more power which doubles, triples or quadruples the power cost of running a crunching computer on BOINC.

It will help keep your host fully occupied all the time, even when a project is down or out of work. The efficiency won't change. The Boinc client will balance out the work credits among all your projects based on your resource share allotment between all projects.

Just a warning, when you add new projects, they will run exclusively for a while and prevent your Einstein and Denis tasks from running. The reason is because of "credit debt" that the client will try to balance out. Eventually when the debt for the newer projects is paid against your average credits for Einstein and Denis, the host will start to run all projects equally based on the resource share allotments.

The balancing can take a short time or a long time and is caused by the different credit systems and awards the different projects use. Some projects award high credit for tasks and some low credit. This imbalance needs to be taken out by the client using the REC algorithm in the client. REC or Recent Estimate Credit has a xml tag in the cc_config.xml file in the client directory.

You can speed up the balancing process by changing the default value in the file from ten days to 1 day. This is done by changing the parameter value. Change this in the <Options> section

<rec_half_life_days>10.000000</rec_half_life_days> to this

<rec_half_life_days>1.000000</rec_half_life_days>

and save the file. Then re-read config files in the Manager menu to apply the new value.

Also consider BOINCTUI if you have a Linux system, may also run under WSL.
This is a text mode interface to multiple BOINC systems.

Paul.

Yes, came in very handy during the Pentathlon for managing remote systems. Interface is a bit challenging but covers all the basics.

I get a dark themed Boinc Manager when I set my Ubuntu OS to dark mode. The only tab in the Manager that does not support dark mode is the Notices tab.

The best optimization comes from running your BOINC projects, 24/7. But with that requirement, you have to figure in your power costs. Can you afford to run your cruncher 24/7, every hour, every day, every month. If you have high energy tariffs, you need to think about how much power you are willing to pay for.

In this matter, the small Soc and/or mini-PC comes to the fore. A lot of the newer mini-PC come with new core and graphics architectures. You can get up to 8c/16t and a embedded gpu that is able to crunch some gpu tasks at projects as long as they have applications.

You will not be able to match the power thriftyness of the SoC or mini-PC compared to a standard PC of older generation. It will also produce the lesser heat output that you have to deal with enviromentally in your location.

If you have very low tariff costs, then the older PC with an 1-2 generation older gpu would provide good output and produce higher output compared to the mini-PC. The heat output of this type of cruncher probably will require air conditioning if used indoors where you live. That adds to the power cost of running the system.
