Ok, i give up then :)

I do understand that sometimes you dont want to mess with other things. I'm not saying he should give up Windows entirely ofc. Just shut down a system , remove the harddrive and put in another one, and boot that Linux USB to install a Ubuntu Desktop. From there a teamviewer session can be made to aid to set it all up and make the WUs fly out of the machines.

If it was to much to cope with, just empty the cache and shutdown to change to the Windows harddrive and never look back.

If you uncheck CPU for seti@home you will only use GPUs if all the other buttons are ticked.
That is the way it is supposed to work though.

Then you have settings in your preferences in Boinc that might behave unintentional if set wrong though.

Yup. Ive been tracking it. I know it does over a million every day. Just waiting for the RAC to get there to be “official” lol.


Niice. Way to go. First ever if so!!

Way to go Mark! U got the best performing Windows machine on top stats.

Do you want help to get going with Linux? We(I) can guide you and then take over the computer to do the rest remote to get to next level!

Keep it up!!

What have they done in the labs?! The servers are responsive and Quick after an outage, result Creation rate just flies. It was only a slight roadbump instead of a massive tornado wrecking it for hours?!

Well done all staff for speeding it up. Whatever you did, you did it flawlessly! *hats off* https://setistats.haveland.com/sah_v8_results.html

Yes, same for me. Seti was very early to be back online again but all times are due to be adjusted in the future. My top hosts are now "disabled" , you'll see that by looking here. https://setiathome.berkeley.edu/hosts_user.php?userid=1635 .. They're not allowed to "talk" to the network. That setting unfortunately affect all boinc Projects but i don't care because i only do s@h solely.

I Use Boinc manager 7.9.3 and got that bug to!

Boinc executable is 7.15.0.

installed with: apt-get install boinc-client from Ubuntu / Debian repository not downloaded elsewhere.

All the results i can see look as intended.

But this one was abnormal :) https://setiathome.berkeley.edu/result.php?resultid=7494014660
Quite cool to have more cputime than actualtime but i guess it's due to what i wrote about. Taskswitching combined with other random stuff that i can't Point on.
But other than that it all look fine. Many gpu results vary in cputime needed to complete the workunit so it's all correct.

This is slightly offtopic!
But i Think that if everyone starts to "delete" their old systems in their their own account the database will shrink when they do a maintenance and removing obsolete computer IDs.
I've cleared up my old computers because why should they ever need to be there when no Workunits have been assigned for ages to that ID.

Thinking this is one part that all of us users can do to minimize ram usage to somewhat degree for seti@home. Get rid of obsolete systems that takes up rows in the database.

The only thing that comes to mind is that the cpu is doing extremely Heavy task switching. (I still can't see the system from S@H)

Seti cpu tasks has a priority level set to lowest, and most other tasks has normal.
So when the O/S decide that it's time for you to have a go to your process it just alow it for a short period of time etc etc.

So the actual cpu time spent on this task is 26 seconds or so, but in reality it took 250+ seconds due to taskswitching (It's a performance costly thing) and different O/S is behaving better/worse.
When more cores/virtual ones comes into play they all compete for internal bus time to-from cache-memory etc.

That's a simplified version of actual process time and real time spent.

We are only few who use this spoofed builds, all are heavy users, with high performance crunchers and besides me (who knows almost nothing) the others are well trained on the "boinc mysteries". We All care about the SETI project and the integrity of the DB and try to do all we can to preserve it. That's is one of the main reason why we keep this builds on a closed circle.


Thank you for explaining.

This is the very first I, and I expect others have heard about the "shutdown" during and after outages, this is to be commended, but I think that when anyone who cares to look can see these 64 GPU machines in the top 20, it might have been a good "PR" exercise to let people know that you weren't "swamping the server"


I know a lot uses the reschedulers (there are a lot of them who works fine), and nobody say nothing about and the impact on the Wu cache is exactly the same


Yes I should probably have mentioned them in my earlier post, however they are not as easy to see, but after what you have said, I hope they are doing the same thing and not swamping the servers with thousands of tasks after an outage and displaying the same community spirit.


I can't speak for that "everyone" does it to 100% in the team, in the guide how to use the Boinc executable i've written about that it's a recommendation to do so because when we all got tasks to Crunch, why should the host act as a part and "steal" bandwidth for 140000 other hosts trying to report/download stuff in a crowded Connection.
If the particular host is participating to that we only add a whole bunch of TCP timeouts to no avail anyway because seti is totally flooded with demand/report requests. We even have a guide that is set to only report 100 results at a time just to prevent these timeouts, because that's only unneccesary requests.

https://setistats.haveland.com/sah_v8_creation.html If we look at this chart (weekly) we can see that after an extended outage it took almost two whole days for the systems to get back to where it was Before. And that is for only a real downtime for about 12 to 16 hours.

Now to me that would appear to help with the slowness of the recovery after an outage, and I think it might just annoy or upset others.

Please note I having nothing against Linux, I have even started a new Linux cruncher yesterday, however I can see how it make make others question things



This is part of our agenda which we have provided as an extra information when using "buffered versions".

".....Again to releave the pressure on the servers to give everybody else what they need until it's time to start to fill up the buffers again.
Why? To use the advantage of GPU spoofed Boinc executable to actually benefit the servers instead of doing DDOS war amongst all other users. Use the benefits of larger cache to ease the pressure instead as a polite favour. "

To put it in Another perspective, my hosts doesn't even try to download after the servers comes live. Aprox. 12 hours after give or take a few hours the first host is allowed to Contact to download workunits, then about one hour later, the other one gets allowance and so on.
We don't want to be part of the flood of users want to get their share of WU's because it's empty or near empty.

Some of us has such amount of fast GPUs so it's needed to try to get something amongst the other perhaps 140K hosts+ or so but for me it's not needed to be part and try to elbow to get work.
So this special version has allowed us to AID instead of hampering the system.
That's a huge difference isn't it.

Post:
I needed to restart boinc too. Seems like it takes some time for the IP to get accepted, once it got accepted it seems to work.
The only struggle is when u got multiple big hosts behind the same WAN ip that also seems to trigger the "block"..

I'm not done there in "think outside the box" yet.. But it seems so because the one host that is at home has never stopped downloading since i fixed this, but the two hosts that reside in another location doesn't start up because there are two hosts from the same WAN ip that demands work and that seems to stop it.

I've set network mode to never on one host now to test.

Seems like it, once i updated the cc_config to accept only one at a time again it seems to go through now.
Needed to nag the retry (in boinccmd it's a mess) but once it got going it seems to let through the others too at a slow pace.
