You might consider the still free upgrade to 10 if you can stomach the forced updates.

The "reset to factory" will reinstall 10, a really nice feature if system has been hosed. you can tell it to keep your files or copy them off like earlier suggestions.

10 includes security programs and updates which are nice.

I have several win7 z400 that I upgraded to 10. Just found out that HP released a new bios for this really old z400 system that addresses that spectre "intel" chip virus. I wish eVga and Dell would update their old bios the same way.

After reading Richards comments I will take your advice and not bother trying to recover those WUs.

One problem I found was when I am able to click the mouse at the correct instant, only those lost units that are within the "max runnable tasks" are recovered.

If I have a limit of 200 and there are 190 tasks on my system then the most I can get is 10. Unlike Milkyway, the seti project downloads a few tasks on every upload so the only way I can download a large number of lost units is to force NNT. However, if I am off by 1/2 second, I will simply get another 200 or so tasks and will have to wait several hours for a second try.

As Richard suggested, a mod to the client can be done to allow this to happen automatically, and he made a suggestion where that mode could go. My first guess was not correct but I could figure it out and build a special client but it is not worth the effort.

Use the "ghost task recovery protocol"

This was really difficult but I was able to obtain 2 out of 100 (or more) lost tasks.

I started a discussion about this over at boinc
https://boinc.berkeley.edu/forum_thread.php?id=13173

You might want to put your 2c into that discussion as I mentioned you.

I forgot to start boinc using suda and it deleted all my work units. I am guessing that even though I am admin on m 18.04 box my apps cannot access "boinc" if they are started under my name.

Is it possible to recover the about 100 tasks?
I meant to started boinc with
sudo /usr/bin/boinc --gui_rpc_port 31418 --dir /home/jstateson/test --detach
but I left off the "suda" by mistake.
5) Message boards : Number crunching : The vintage cruncher (Message 2015211)
Posted 8 days ago by Profile JStateson
Post:
I recently pulled my SETI@home Classic cruncher out of storage and to my surprise it still boots and runs great. It's also in excellent condition. The specs are: Apple "Blue and White" G3 450mhz with 1GB PC133 RAM and the ATI Radeon 9200 128MB Mac Edition PCI. It dual boots Mac OS 9.2.2 (about 15 seconds on SCSI) and Mac OS X 10.4.11 (over 1 minute on ATA66). It does have a Fedora Core installation but that no longer functions (big surprise). My SATA 1 card is dead so all I have is the original 9GB drive connected via SCSI and a 60GB drive via onboard ATA66. The machine makes for a nice conversation piece in front of the fireplace.

Is this sexy beast still usable?


Hibachi?


Pet box for display?


Sorry, I could not help myself.

I think before the next WOW event i need to put my experimental 16 x 3070 mining auto bunkering host running the multi spoofed new client working or i will be doomed


Auto bunkering is not that far fetched. I have come up with a scheme that can do it and will run some tests. Not going to give away any secrets but I might trade for secret inside info from the GPU Users Group.

This brings up an idea for a contest. What is the oldest waiting for validation status work unit anyone can find?
Keith said hes got one from wayyy back on may 6th and its on its 4th wingman possibly going on a 5th wingman. Care to update us Keith? Can anyone beat Keiths workunit?


My oldest is July 19. Not even close to May.
https://setiathome.berkeley.edu/workunit.php?wuid=3569252203

Except for a few 100 that I recently downloaded, all my pending are from the WOW event. With cooler weather coming I will start heating house by firing up the SETI rig.

Guessing also that the WOW score is based on credits earned during the WOW week even if the work had been done days before and submitted 1 second after the start. I actually noticed a huge jump by one setizen just after the start.

That is called bunkering or nuclear weapon deployment during the first week of the WOW contest. Lots of people were dropping big A-bombs constantly to goose their credit tally. All in fun and a lot of work gets done trying to one up your competitors.


Got to thinking about this and decided to run a test. I downloaded 100 SETI (8.22 SoG win) tasks a minutes ago (Oct 11)
Deadlines for the about 100 are 12-2 through 12-11 and eye-balling: most due on 12-3 followed by 12-11 then 12-7.

Bunkering up oct:20 +nov:30 +dec:3 maybe 50 days to bunker
Cuda90 linux anon-platform takes 2 minutes per work unit. With six gtx1060 get about 14000 credits per hour

----conservative calculation ---

Assuming the limit of 900 work units per linux system that does not upload results:

With 6 GPUs at 2 minutes per WU, the 900 limit will be reached in 2 * 900 / 6 or 5 hours. After 5 hours I boot another new linux system.
For a total of 50 days I will need 50 * 24 / 5 or about 240 flash drives of 16 GB each, maybe 8 if minimum ubuntu system

In credits that gives 900 work units for 240 systems averaging 77 credits per WU or 16,632,000 credits
That just 2x over what I accumulated duringt WOW
https://www.seti-germany.de/Wow/stats/users/2019
The 900 limit can be bumped up by spoofing the number of GPUs.

1. Bunkering: 50 days
2. 240 nukes dropped
3. Banana up the tailpipe: Abort all workunits that expire before the start of the WOW event.

Lemme know if I left something out!

Post:

So, has anyone used an Intel GPU on Linux successfully?


I gave up trying to get my Haswell CPU to crunch in Ubuntu. All indications that only 6th gen and higher are supported. However, that Haswell works fine in Windows. The same "beta open cl" app worked (but overheated) on my surface pro 4 "Skylake cpu".

https://einsteinathome.org/content/surprise-i-picked-intel-open-cl-app

Running 18.04.3, I was unable to get HD7950 and the RX series or AMD boards to co-exist. Same for HD7950 and S9000 although they are both Tahiti based. Not sure if nVidia is better under Linux as I don't have a mix of different boards like I do for AMD. I have had no problem running a mix of Nvidia and AMD under windows. Would not want to try that under ubuntu.

Little chance of your suggestions being implemented here at Seti. The main project scientist is set in his ways that Seti remain an "everyman" project configured to run on as many possible devices and with all levels of participation from extremely casual, once in a blue moon types to dedicated hyper crunchers. I know that is not going to change, I have no chance of persuading otherwise and just accept the status quo.


I had similar thoughts during the WOW event in August. I was wondering if the German organizers coordinated with the SETI folks to ensure minimum down time and faster turn around for the participants.

I am guessing that nothing special was done. Looking back at my pending tasks I see a lot of pending that I completed during the WOW event. Before that, the oldest I see is mid July. All the pending wingman ones I checked were CPU bound. Some wingman had timed out and the work unit had not yet been sent back out. Those were like three months out.

My guess, as far as the WOW event goes, that every participant has the same chance of getting a bummer wingman. Guessing also that the WOW score is based on credits earned during the WOW week even if the work had been done days before and submitted 1 second after the start. I actually noticed a huge jump by one setizen just after the start. I enjoyed participating and hope I reduced the backlog of workunits. It would be nice if it was not held during the hottest month of the year of the northern hemisphere.

I have experience only with Ubuntu, not sure what you are running. However I have found that attempting to "kill" or "start" tasks manually causes ownership problems when the tasks try to talk to one another. if you start or stop the client be sure to use the designated service call.

Except for the links to the xml files, all the boinc files (var/lib/boinc-client) should be owned as "boinc:boinc"

The chart, the way it is drawn, makes it seem the east is feeding off the west, probably its intent.
Another way to put is that the west/north pay the east/south to feed the west/north. Food would be very much expensive in the west/north if we didn't.


That is not the way I would put it. Re-phrasing: The intent of the chart, IMHO, it to make it seem like the east European nations are SUCKING THE LIFE BLOOD out of the west European nations. In reality, nothing like that is happening, it just looks like it.

The chart does show the small and less affluent countries get a bump in their incomes and the larger more affluent contribute a small portion of their incomes to create that subsidy.


Agreed. The chart, the way it is drawn, makes it seem the east is feeding off the west, probably its intent.

Looks like a net deficit to me. Either they stored away a pile of euros for a rainy day or they are minting euros like gridcoins.

Since the gross national incomes are not stated how do you draw that conclusion?


I assume they normalized it as would be done in any legit study. Clearly, I was mistaken.

I am trying to do this. At the end of WOW I checked and one of my system has over 200 missing tasks "in progress".

They are all of type
SETI@home v8 v8.22 (opencl_nvidia_SoG)x86_64-pc-linux-gnu

I tried that procedure twice, exactly was specified but only downloaded more of the cuda90 tasks. I think those SoG tasks are left over when I changed to the anonymous platform for cuda90.
You'd (somehow) need to check the actual WU names involved (eg blc35_2bit_guppi_58643_81781_HIP30272_0117.24267.818.23.46.55.vlar, 21jn08aa.4823.11933.16.43.106.vlar_1 etc) as "SETI@home v8 v8.22 (opencl_nvidia_SoG)x86_64-pc-linux-gnu" is just the name of the application that has been assigned to process the WU, not the actual WU's name. Since you're now using a different application, that is the name that was assigned to the WUs this time around when they were actually downloaded.


I detached and re-attached and all the tasks were marked as abandoned. I then restored the anonymous platform to run that cuda90 stuff. At least the server knows not to wait for any results from me.

While doing this I went and did an update and upgrade to (18.04) and saw the following error messages
Setting up boinc-client (7.16.1+dfsg+201908161115~ubuntu18.04.1) ...
usermod: group 'render' does not exist
Could not assign boinc user to group 'render'


Boinc terminated during the upgrade but a restart went ok. AFICT those errors are ignorable.

sadly i found no remote viewing software that works. correctly. from home net work to across the city etc.


I found Anydesk works for me. It allowed me to access my home network when I was travelling across the USA last year.

I backed up all my pictures from my laptop to my home PC.

Works on Linux as well, for the WOW event I have 5 "headless" Linux boxes and use Anydesk to remote into them no problem



I was not aware of anydesk. I have been using splashtop and paying $17 a year for 5 access anywhere connections but I supplement it with RealVNC for Linux support in the subnet (5 free).

I read that anydesk is free for personal use but I did not see any details like how many connection can be used of if it only works in the subnet, etc. It appears you can drag and drop stuff using anydesk. Is that included in the free-for-personnel-use ? I cannot do that in my $17 a year subscription although text can be pasted.
