. . I am running your boinc client 7.14.2 on three Linux machines but I am getting slightly flaky results. While I did not change any settings on setup two machines are behaving very differently to the third. The odd machine is not displaying "ack" messages in the log but the other two are, it is also displaying the stats page normally while the other 2 are plotting all RACs from the date of the creation of that machine (after nearly 3 months it is getting very squeezy on that graph). Is there a way to change this behaviour? I know there is a setting to reduce messages in the log but I cannot remember where that is, but I have not heard of any setting for the stats tag in manager.

? ?

Client configuration

Logging:

<sched_op_debug>
Details of scheduler RPCs; also shows deferral intervals and other low info.

(including acks)

Options:

<save_stats_days>N</save_stats_days>
How many days to save the per-project credit totals that are displayed in the Statistics tab of the BOINC Manager. Default is 30.

the other 2 are plotting all RACs from the date of the creation of that machine

The period of time for which the Manager displays the RAC can be set- i had all my RAC on one system (till a crash) from when i first joined the BOINC version of Seti. From memory the default is 30 days?

<cc_config>
   <log_flags>
   </log_flags>
   <options>
       <save_stats_days>3665</save_stats_days>
   </options>
</cc_config>

Edit- Richard beat me to it.

Is there a Boinc Screen saver for Linux?

I understand that trying to balance multiple projects on one box is tricky.

My goal is to run a mix of projects on my cpu threads. The gpu's are all Seti@Home, all the time.
The cpus are currently Seti@Home 2 threads max. (resource 1000) (1 in cache, 1 running)
Seti@Home Beta 1 thread max (resource 10) (44 in cache, 1 running) and
World Community Grid 5 threads max (resource 100) (5 in cache, 5 running).

WCG is already constrained so it doesn't bury my cpu tasks with unlimited tasks.

The cpus are set to 90% which translates into 14 threads available.

What I am missing is 2 S@H threads running. I have 1 running now and the log reports it didn't ask for any more S@H cpu work.

Sun 24 Nov 2019 03:37:54 AM CST | SETI@home | [sched_op] CPU work request: 0.00 seconds; 0.00 devices

If I set S@H Beta to NNT (no new tasks) and delete the bulk of the Beta tasks then S@H cpu tasks are downloaded and "all is good".

Any ideas about how to get 2 S@H cpu threads to be fed constantly (besides dropping Beta and WCG :)

Maybe by using <project_max_concurrent>xx</project_max_concurrent>

Seems to work on my laptop, it's only running CPU tasks on SETI & WCG. I have set WCG to 3 project_max_concurrent.

I am currently investigating using Ubuntu to run Boinc/Seti@Home. I have one computer running Ubuntu 18.04 and it is doing well on SETI. One of the reasons for switching from Windows is that Ubuntu could be running Tasks faster. Early results suggest that there is no increase in speed - maybe some lose in speed.

I am in need of the CUDA app some times referred to as the "Special Sauce." How do I get it? Can anybody help me?

Using "stock" and the "normal" optimised applications it is normal for there to be very little difference between Windows and Linux (on the same hardware). However the special sauce is a huge leap in performance - others wil be around to give you the low-down on how to find it and run it.

This is most useful for the Nvidia gpu "special sauce". I am uncertain if the cpu apps in it are better than stock. They might be as fast as the Lunatic's cpu app though.
Try this link. It should download the archive: http://www.arkayn.us/lunatics/BOINC.7z

If you don't have an un-archiver let us know.

Tom
ps. I think this is the system you are experimenting with? https://setiathome.berkeley.edu/show_host_detail.php?hostid=8852490

Ubuntu's Archive Manager doesn't natively understand 7zip compression. Add it to the Archive Manager with:

sudo apt install p7zip

Mint apparently does understand 7zip compression natively.

Since you are running the distro version of BOINC, you either need to uninstall the distro version and run the TBar version included in the package.

Or copy the science applications and support files along with the app_info.xml file into your distro BOINC folder and restart to come up on the anonymous platform.

You need to set NNT on your current tasks and run them out before switching or you will abandon your current work.

. . Looking at Frank's results there it is so clear why running "stock" using Linux is a trap. You keep getting Cuda60 tasks which are like entering a foot race by cutting off one leg ... such a sllooowww app, why do they persevere with it? Sorry just a little peeve I have ...

I agree. Only benefit is someone running older drivers and haven't updated and haven't installed any OpenCL drivers. At least they would get work for the CUDA60 tasks.

. . True, some might not have drivers with OpenCL support ... but what a penalty ... :(

Or for those running GPU's that don't support the Special Sauce app.

Cheers.

True. Anyone running Nvidia cards with less than 5.0 Compute Capability would still need the CUDA60 app. Unless they dug around the forums for the link to the zi3v special app which can run on CC 3.5 cards.
