I did the CUDA thing and 1804 is gone and 2004 is in it's place, so I tried that and of course it failed as I'm using Linux Mint 19.3. I will work on just the Lib 10 files


https://mrprajesh.blogspot.com/2018/11/install-cuda-10-on-linux-mint-19-or.html


Thank you but it fails at the part where it says wget...cuda-repo-ubuntu...and says no such directory


There is no wget command on that web page !


It's on this page https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&target_distro=Ubuntu&target_version=2004&target_type=runfilelocal

I also tried the "runfile(local)" option at this site https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&target_distro=Ubuntu&target_version=2004&target_type=runfilelocal and it got to the 98% range and stopped downloading.

I'm guessing either I have the wrong version or don't have enough knowledge and will just run it on my Windows pc's and be happy.

I can run the TF tasks in my windows pc's with no problems but on my every single one of my Linux pc's every single task errors out. Any ideas on how to fix it?

I just checked one and it says
"Stderr output

You must install cuda libs 10, see FAQ

6) Message boards : Number crunching : Task Deadline (Message 6699)
Posted 17 Aug 2020 by Profile mikey
Why some tasks always have deadline 24h from now? Is this mean they will never time out?
for example,
http://srbase.my-firewall.org/sr5/workunit.php?wuid=8240653
http://srbase.my-firewall.org/sr5/workunit.php?wuid=8242659
http://srbase.my-firewall.org/sr5/workunit.php?wuid=8253545
http://srbase.my-firewall.org/sr5/workunit.php?wuid=8254323
http://srbase.my-firewall.org/sr5/workunit.php?wuid=8251071


Do you mean the middle task, it's because it was aborted and that's the date and time it was returned?

Do you have changed something on your config? Does all your hosts are affected?


Nothing changed apart from the VMs that I can think of. Other PCs get SRBase CPU tasks. It's just wierd.

I don't believe it! I just added SRBase (CPU only) to the Win 10 VMs and said go for it and got a single task on each, but when I looked at Boinc on the actual PC it had gotten 700+ SRBase CPU tasks - before i did this it would not get any.

This must be Virtual Machine related., but at the moment I haven't got the time to look into it, but there definitely seems to be some link between the Virtual and The Real! It's all gone a little bit Quantum! ;-)


What is the resource share for each Project you are currently running? You said other projects get tasks making me think the other projects need processing time because of the 'resource share' that Boinc is trying to maintain. ie 50% here, 25% at 2 other projects makes 100% crunching time. You can also use 500%, and 250% twice to come up with the same thing.

Posted 12 Aug 2020 by Profile mikey
When I first visit the work unit at around 6 Am UTC today, the deadline is at 6 AM UTC tomorrow.
But now whenI visit it agian, the deadline move to 16:20 UTC tomorrow. So it's always move away and seem to never timeout.


You were always processing that task, so BOINC moves it backwards.


Cool!
9) Message boards : Number crunching : Multithreading / app_config.xml (Message 5592)
Posted 10 Jan 2020 by Profile mikey
It works fine even if a client has never ran all of the apps.

srbase = Sierpinski / Riesel Base
srbase2 = Riesel Base
srbase3 = Sierpinski Base
srbase4 = Sierpinski / Riesel Base - short

These aren't even long enough run times to need mt setup.

If the app_config from the FAQ isn't working its because of the part in ( ).
<avg_ncpus>4</avg_ncpus> (for WUprop optional)


I'm running the Sierpinski / Riesel Base - long workunits, do you happen to know the name and number of it?

I agree the ones you listed aren't worth assigning multiple cores for.

ps--never mind I guessed and counted down from the top of the app page and it's srbase5. The file is now working running 3 wu's at a time and using 6 cpu cores for each one.

pps--well poop!! Every wu running multi-threaded crashed after running for 5 1/2 days single threaded, I thought that might happen but was getting concerned that they wouldn't finish in time if I left them alone.

Sorry to all my wingmen I was trying to return them in time!!

That's ok,

I'll just run with this.....

<app_config>

<project_max_concurrent>24</project_max_concurrent>

</app_config>

If there is a better way I'm all ears....


That has very little to do with multi-threading, all that does is tell your pc to run a max of 24 workunits at a time.

You need something like this:
<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>

But this one is forPrime Grid and NOT SRBase.
Note that it has a maxconcurrent of one workunit and then is set to use 4 cpu cores for that single workunit.
