Gee Wiz, just look at the long list of BLC files queued up on the Server Stats Page.

Are we near the end of Arecibo work?

So, with that long background, my basic question is perhaps simple:
    Where can I find documentation of those parameters?




The documentation can be found in

C:\ProgramData\BOINC\projects\setiathome.berkeley.edu\docs

The parameters should be tailored to a specific type of graphics card and if you have a dedicated cruncher PC or need to use it as a general-purpose PC.

Look what has appeared in the SSP;
blc03_2bit_blc03_guppi_58107_15277_OUMUAMUA_0018
Is it....it has to be, only one OUMUAMUA that I know of.

Looks like SETI@home is getting these work units.

Intersellar water - what an amazing thought on how building blocks of life could be carried across solar systems.

Tis only 07:30 in Berleley, my guess, and it is only a guess is that maintaintence probably will start later today as the database is so fragile.

Let's hope that the servers behave themselves over the festive season and the team in the SETI@home labs can have a well-earned and peaceful break over Christmas.

SETIspirit  News  Update

I am very happy to announce the new SETIspirit release v5.0.0, which will be available soon on 24. December.
It's a new major release with lots of improvements and new features.

I wish you all a happy and merry Christmas.

Regards,
Dirk
 


Great news, an early Xmas present.

Something for the next release maybe. Could SETIspirit also plot the position of POGS work units? Looking at the POGS website there is a plugin for some desktop astronomy package so I guess there is an API that could be used.

Regarding Windows 10 Creators Fall Update I just luv the new "controlled folder access" in Windows Defender. To quote "Apps determined by Microsoft as friendly are always allowed". So why if I turn controlled folder access on is Internet Explorer blocked from updating its config settings?

Thanks David,
I will look at this, but my app_info is large (standard one created by Lunatics), so not really sure which applications I need to create in the app_config file, so I will leave this alone as I do not know what I am doing and shall probably break it :-)

Thanks


Yes the Lunatics one is complex. Try just creating an app_config for Milkyway and limit it to 8 CPUs. Then SETI would get at least 8, and if Milkyway had no work SETI would run on the other CPUs until some work became available again at Milkyway.

Would only need to contain

<app_config>
<project_max_concurrent>8</project_max_concurrent>
</app_config>

That's the approach I posted earlier that I think the project should take. Just take the project down and fix the servers properly and take as long as needed. I can't handle the constant band-aid up and down lately.


+1, I think the SETI team should do that and get ready for Parkes by taking things offline and doing whatever is needed to get the Database sorted.

Looks like my PC survived the night and managed to keep enough work in the cache. When I went to bed the cache was very low and I was half expecting my backup project to kick in, but in the end it didn't.

Anyone had successful contact with the Scheduler in the last 25min?


No, same hear. Communication deferred for 20 minutes. Hopefully not a sign of database issues.

Forum also very slow to respond.

You could also try a custom app_config.xml for each project and set max_concurrent (the maximum number of tasks of an application to run at a given time) to 8. This would split your CPU 50:50.

I used to use this when I ran POGS as it was so aggresive with deadlines and timeout between connecting to the server that it pushed SETI out.

Apologies, my mistake, Windows shows BOINC Manager using 100% CPU in Task Manager. However, if you click the little > sign against the BOINC Manager process it opens the sub tasks under BOINC Manager and there are the individual Work Unit tasks burning the CPU as expected. Windows Task Manager got me all confused.

Mine doesn't.
BOINC Client & BOINC Manager for Windows & BOINC System Tray for Windows all have their own lines. The crunching applications (MB_win_x etc) each have their own line further down (list is sorted by Name).

Have you got the Fall Creators Update?
When they added on the GPU reporting they might have made some changes to how the CPU processes are arranged.


Yes, just recently installed the Fall Creators Update. I now have GPU reporting and I think that the ">" sign must be new as well as I haven't used it before.

Made me jump when I saw BOINC Manager at 100% CPU! But it is explained by the sub-task grouping in Windows Task Manager.

Wonder if we will see those observations appear in the SETI@home work units?

Post:
Just noticed that when using BOINC Manager on my PC it grabs nearly 100% of the CPU cycles. Project WorkUnits will be straved of their CPU cycles.

Is there a recommended alternative?

p.s. Recently updated to Windows Creator Fall Edition. No idea if it is related as I hadn't run task mgr before when BOINC Manager was open.
