I still don't understand why projects keep using CreditNew, it's been a pain since it has been created ...


Because it's the default meaning it's built-in into the Server side version of Boinc. to change it one Admin, not from here, said there were like 3 places in the software to change it. He said it was not as easy as it sounds!!

To be honest, I have no idea.
I suppose your hosts are either Windows or Linux64 and you have at least 64 or 128 cores.
There were always tasks available for 64t and 128t apps in the last months.


I figured it out, I had less than 100% of the available cpu's scheduled to be used to keep the heat down and it was less than 128 cpu cores, I now have BOTH a 64t and a 128t task ready to run.

Yes those assumptions are correct about my pc's, well I use a cc_config.xml file to make it think it has enough cpu cores available. And overnight I am getting lots of 64t tasks but still no 128t tasks.

Here is the line where I do it:

<ncpus>140</ncpus>

Why does it always say there are no 64 or 128 tasks when the Server Status always says a few hundred are ready to be sent out? I know it's behind but THAT much?

New version 212.02 for Linux.
If the app is in a later running phase and a nfs.dat file was created, resume should also work.


I am using Linux Mint and when I try to reset the Project it doesn't seem to do anything, most of my Linux pc's get tasks just fine, as do my Windows pc's but this one just won't. It's running Boinc version 7.18.1 so isn't that old.

Never mind on the above I had it set to No New Tasks and once I clicked 'resume' everything worked just fine!! I have new tasks running on the pc now.


Your message above says "resume should also work" but I don't know what that means, can you explain that please.

Post:
Please add GPU support to the project.


I don't want to discourage the Project from doing it but Boinc gpu programmers are not a dime a dozen and the projects don't share people like that between them. I wish alot of things would happen to Boinc, sharing people between them would help alot but each project just seems to do their own thing and even only rarely ask in the Admin Boards for help when they are having problems.

Posted 16 Dec 2023 by mikey
Post:
Why not whitelisted? That's weird IMO.


The Project has to agree to be whitelisted and some projects think it will increase the cheating, it already did at Collatz just so people could get more GC's, so more than a couple of Admins don't want the problems.

Credits themselves are worth nothing physically but do show your progress here at Yafu compared to other users here at Yafu. Credits should NOT be used to compare yourself, or anyone else either, and the credits at other projects. Each Project decides how to give out credits, some use this formula, some use that formula and still others give out fixed credits.

Post:
I have 32 logical cores cpu nad had 2 yafu task running 8cpu + 8cpu so half of cores were not utilized. Selected to receive YAFU-16t tasks and I got one YAFU-16t waiting to run on 32 cores !
Wunderfull.
So I had to delete that task, set usage limits to 50% in boinc manager preferences and ask for task again and then set it back 100%.
Hopefully I got what I wanted and my cpu was 100% utilized (not most of time of course but sheduled to).
But I don't uderstand why yafu scheduller selects cores this way. Simillary I cannot choose in yafu project preferences cpu limit higher than 8 cores what is quite outdated and I have always got 3*8cpus tasks on 32cores cpu. And nothing more when cpu limit is set to 8cpus.


You can always choose 'no limit' but yes if decide to limit the cores 8 is the highest and yes it needs to be updated to 32, though maybe not every number in between 8 and 32

Post:
Yes, 4t now meams, that you need at least 4 cores. The wu uses all cores.


So what does that mean when I choose to do the 8t tasks and choose this in the settings?
Max # jobs 8
Max # CPUs 4

Does it mean it won't work or just take longer to run them?

I have both windows and Linux pc's asking for 16T and 32T tasks and the Server Status says there are some but I never get any of them..is there a secret to getting them? I do have my pc's limited to 99% of the cpu cores meaning only 15 cores available...is that a problem getting these tasks?

Posted 19 Jan 2021 by mikey
Post:
I think the answer is "yes" Mikey.
A 1950X will use all 32 threads to crunch a 32t task.


I figured that but am wondering if I NEED a 32 thread machine to crunch them? Can I for example fudge the numbers and use a 24 thread to make it THINK I have a 32 thread pc or do I even need too.
The short answer is I can't seem to get any of the 32 thread tasks and me not having a 32 thread machine seems to mean I will never run them.
14) Message boards : Number crunching : YAFU running with GPU's (Message 1547)
Posted 23 Dec 2020 by mikey
Post:
I'm running 4 GPU's
3-RX480's (collatz) and
1 motherboard GPU (Einstein) also WUprop and iThena non-intensive cpu
Boinc Mgr states each RX480 is using 0.994 CPU and the motherboard CPU is using 1.0.
YAFU runs 4T and 8T workunits at the same time the GPU's are running. Does this affect the processing in anyway?


Maybe, it depends on your machine and how the Collatz and Einstein apps deal with your 480's, some gpu's require a cpu core free for each gpu so they can run at their max of they are limited while others do not. The best thing to do is run a few cpu units using all the cpu cores and track the time used to crunch the gpu tasks, then suspend all the cpu tasks and track the time to run some gpu tasks again...which way is it faster. Since gpu tasks do over 10 times the work cpu's do it's better to optimize them and limit the cpu tasks. And THAT is why people end up with muplitple pc's, people hate to slow down so you get more pc's spread the gpu's out into separate machines and bang out a bunch of both.

The big ones use every core they can find if not constrained.


So are you saying I need a 16 or 32 core machine to run the 16 and 32 core workunits? I know how to constrain them thru the settings but am asking as I do not own a 32 core machine.

Here is another example of incorrect CPU time -vs- run time:
http://yafu.myfirewall.org/yafu/result.php?resultid=5592660

The task was running on a Pentium(R) Dual-Core CPU E5300 @ 2.60GHz
Run time 16 hours 55 min 58 sec
CPU time 3 hours 6 min 56 sec

I abandoned task because it quit accruing CPU time despite the Run Time increasing every second..
I am guessing CPU Time should of actually been close to 1/2 of the Run Time or aprox 8.5 hours.

Appears somehow the BOINC wrapper that the actual science tasks runs under lost track of what the science app was doing.


It seems your dual core pc's only have 2GB to 3GB of ram, I wonder if the task is spinning it's wheels due to not enough ram?

Have you tried going into the Boinc Manager to see how much each task is using? Click on a running task and then to the left click on properties and near the bottom it will show something like this:
Virtual memory size 33.12 MB
Working set size 22.60 MB

That's the number for a NON Yafu task as I don't have one running on this pc right now but you get the idea.

Hi YoYo, When you define your own class plans (<plan_class>16t</plan_class> & <plan_class>32t</plan_class>) don't you have to pass the client your plan_class_spec.xml file???
https://boinc.berkeley.edu/trac/wiki/AppPlanSpec

This app_config.xml is not working to control number of threads used:
[code] <app>
<name>yafu-16t</name>
</app>
<app_version>
<app_name>yafu-16t</app_name>
<plan_class>16t</plan_class>
<cmdline>--nthreads 16</cmdline>
<nthreads_cmdline>1</nthreads_cmdline>
</app_version>
<app>
<name>yafu-32t</name>
</app>


BTW, can't see the check marks in my Yafu Preferences Run only the selected applications.


This is the app_config.xml file I use at another project to run 1 workunit at a time and use 4 cpu cores per workunit.
It is a 6 core machine so only 1 unit can run at a time.

Obviously you will need to change the "llrsr5" line to the app used here and put it in the project folder for Yafu.

<app_config>
<app>
<name>llrSR5</name>
<fraction_done_exact/>
<max_concurrent>1</max_concurrent>
</app>
<app_version>
<app_name>llrSR5</app_name>
<cmdline>-t 6</cmdline>
<avg_ncpus>4</avg_ncpus>
</app_version>
</app_config>

That cache setting relies on BOINC calculating an accurate completion time. Yafu jobs run much longer than BOINC calculates. The only way would be to limit actual number of jobs retrieved and I don't see a setting for that in BOINC or in cc_config.xml options. <fetch_minimal_work> comes close, but it only restricts the number of jobs to the number of CPUs.


If you use a zero resource share it will only get one workunit per cpu that you allowed to get work in Boinc. For instance I have a 6 core cpu but am only allowing to use 99% of the cpu's so it gets 5 workunits. I reserve one cpu core to keep the gpu fed for the gpu workunits, from another project, I also do.


Right... but they've got at least 16 cores and don't want more than 2-3 jobs at a time (definitely not 16)


They could use this setting under 'Preferences' "Max # of jobs for this project".
I also use the setting "Max # of CPUs for this project" and set it to 2 so only 2 cpu cores are used per workunit.
