Clomate prediction then refused to request work because it was backed off?????

Of course!
Each time that your computer contacts the server, it gets a 1 hour and 2 minutes backoff.

So, first you set up your changes, then you wait an hour, and THEN you can make use of those changes.

I did finally work this one out.

As the computer repeatedly gets knocked back it extends the time between requests until it’s only requesting work once a day. It still only shows the one hour back off on the project screen but in reality the back off state lasts 24 hours and that back off clock is not only affecting commas but is also blocking work fetch.

Bryn Mawr -

Sorry to read you can't get any work. I have 5 or 6 computers and it has worked for me every time.

You have the same OS and AMD processors as me.There must be something that I haven't encountered yet.

Frustrating but that’s life.

Is the "os" in a VM?
Is it connected to any other projects / running work for other projects?
Any config type files, that alters how it looks to the outside world?

3. Place the following three lines in the file.

<app_config>
<project_max_concurrent>4</project_max_concurrent>
</app_config>

1.) I did that.
2.) I set No New Tasks for all projects, allowing everything to drain off.
3.) I set 10/10 for minimum and maximum additional days.
4.) Probably not relevant: I allowed a system update to take place. Did a reboot.
5.) Allowed CPDN to Get New Tasks. Got 14 of them.
6.) I set 1/1 for minimum and maximum additional days.
7.) Allowed WCG to Get New Tasks. Got 9 of them.
8.) It is currently running 14 CPDN and 2 WCG tasks on my nominal 16 processors.

I am not sure what

<app_config>
<project_max_concurrent>4</project_max_concurrent>
</app_config>

is supposed to do.

It should limit the number of tasks running at once for that project to 4.

Jean-David Beyer -

I think you wrote that my suggestion on how to get work was successful.

You did write that you are now running 14 CPDN tasks.

You should note that Les Bayliss has written several times that you need 4 Meg of L3 cache per task or progress slows WAY down. I think you have 16 MB of L3 cache which means 4 concurrent tasks might be optimal. But you will have to experiment to determine that.

Either it does not work, or it must be set before the work-units are started, right?

No. It works and it can be "created" anytime. Make sure you put it in correct location, in this case the /var/lib/boinic-client/projects/climateprediction.net folder.

Then go to Options and Click on Read config files.

Check the log to make sure BOINC didn't find any errors. I have been down that path many times before.

Out of curiousity, will the Linux subsystem for Windows allow one to download Linux tasks for windows if the correct libraries are installed? Or how does that work?
Thanks!

Not sure which way round you're wanting to do it, but I have the same question. I use Windows 10. This program allows Linux to run under Windows. Can I therefore run CPDN Linux tasks in Windows 10 Boinc?

On my Red Hat Enterprise Linux release 8.2 (Ootpa) machine, it is in a skightly different directory. When I installed boinc and boinc manager, that is where they went.
# cd /var/lib/boinc/projects/climateprediction.net/
]# cat app_config.xml
<app_config>
<max_concurrent>4</max_concurrent>
</app_config>

I infer something is wrong, but do not know what I am missing.

# cat /var/lib/boinc/notices/www.cpdn.org_notices.php.xml
<error>
<error_num>-155</error_num>
<error_msg>Invalid authenticator</error_msg>
</error>

I guess the first thing to try is will the Linux version of BOINC install under it? There is a self extracting file to try seeing as you clearly can't install from the repositories for the various distributions. I don't have a Windows box to try it out on or I would check myself.

Edit: I suspect this may not be possible or I would have expected to see some mention of it over on the BOINC forums where a quick search doesn't produce anything.

It should be project_max_concurrent not max_concurrent

On my UBUNTU system there are folders boinc-client and boinc. The boinc folder is a pointer (or whatever it is called) to the boinc-client folder.

I tried max_concurrent instead of project_max_concurrent and the Event Log clearly shows (highlighted in red) that the app_config.xml file is faulty.

A pointer is a "link to folder".

This is the page for the config files: Client configuration

Project-level configuration, which is where app_config.xml is, is about 2/3 of the way down.

I assume you are talking about using HyperV as a virtual machine. As you would need to install a Linux OS inside this machine then I guess the answer is yes. Be aware that if you use HyperV then probably no other VMs can be installed. It certainly doesn't like to co-exist with VMware - I tried it.

That fixed it: Thank you very much.

Hi,

I have an Intel i7-7700 CPU with 16 GB RAM running Windows 10 at 3.60GHz with 256 kb L1, 1,0 MB L2 and 8,0 MB L3 cache.
The current project settings are to download at least 10 days of work, with an additional 10 days, and to use no more than 40 GB of disk space.
I have 8 other projects connected to this pc, but all of them are currently out of work, and set not to fetch any new work.

There are currently 4823 units for "UK Met Office HadAM4 at N216 resolution" available for download - but I'm not getting any work...
Is my pc too weak or slow to recieve any new work from this project, or do I have to change any setting/use specific settings in an XML-file to get some work units?

Regards

HADAM4 tasks are Linux only. For Windows you will have to wait until there are some more WAH2 tasks available or run them using Linux via Virtual Box or another virtual machine system. For more information about different types of task see
this post

Ahh - ok. Thanx!
