Fix the expired SSL certificate error in BOINC. Look for help on the BOINC forums where this issue has been extensively discussed with multiple solutions.

Basically any project that offers an ARMv8 application. Currently running TN-Grid and Minecraft on the cpu cores and the Einstein BRP4 gpu app on the Maxwell cores.

I think it gets a decent amount of work done. Obviously the CUDA cores are the most efficient. I can do a BRP4 app in 10-11 minutes. The cpu cores run typical times compared to a RPI that isn't a Model 4.

Use the BOINC forums for assistance. https://boinc.berkeley.edu/forum_forum.php?id=10
Or wait until BOINC can release a new client without the offending file.
Dr. Anderson posted a fix here. https://boinc.berkeley.edu/forum_thread.php?id=14422

Glad to hear it is working for you again. Future BOINC revisions will get rid to that file entirely and we shouldn't have these issues crop up over and over again.

Others have found that there are additional copies of the ca-bundle.crt file in upper level directories that BOINC is using still that has the expired certificate. Either remove the other copies or replace/edit them as well.

Look for other copies of the ca-bundle.crt file in the host. Others found another copy in C:/Program Files that BOINC was finding still over the edited copy in C:/Program Data/BOINC and was still fouling up connections.

Either edit those additional copies or just delete them. The only one needed has to be in the BOINC folder.

Yes, unfortunate since there hasn't been any ULX work in months. All the ULX crunchers complaining did nothing but hurt the RAC and PPD of the BHSpin crunchers who have plenty of work.

Post:
It all depends on what tasks you are crunching in the series cycle. The cycle has short runtimes, long runtimes and then short runtimes again.

And then the next series starts and the cycle repeats.

You can't just proclaim that all your tasks run in xx amount of minutes. It varies during the cycles. And varies in the parameters being passed to each work unit.

Your current tasks are completing in 33 minutes.

They said they would be cutting the credit for BHspin in half after the ULX people complained that BHspin awarded too much for the same time spent crunching.
Assume it is permanent as no other changes are expected.
Comment was made that they could have just doubled ULX instead.

Sorry, I didn't help. I have never had to go down this path because the one ARMv8 device I have, the Jetson Nano doesn't have the arm-linux-gnueabihf 32bit libraries in the distro. And the kernel is locked down also. So even after I researched all the methods of getting 32bit libraries recognized, I was still stymied.

And also never felt like having to recompile the Einstein BRP gpu app if I upgraded to the latest Nvidia Jetpack SDK. So still rocking the base Ubuntu 18.04 with 4.9.140-tegra kernel

I do not know what how to do this
export the 32 bit libraries to userland for the application to see them.

Well first thing to try is to link them with ldconfig. Figure out where you installed the 32bit libraries and link them to /etc/ld.so.conf.
Probably they installed to /usr/local/lib
Run ldconfig in terminal with the location of those libraries. Or. . .

Check what ldconfig sees in the first place with
ldconfig -v


See if the 32bit libraries are listed. If not
sudo /sbin/ldconfig -n /lib


Try
LD_LIBRARY_PATH=/usr/lib/arm-linux-gnueabihf/
or. . .

LD_LIBRARY_PATH=/usr/lib/arm-linux-gnueabihf/ ldd /usr/bin/projects/universeathome.pl_universe/BHspin2_19_armv7l-unknown-linux-gnueabihf
or . . .

make permanent with . . .
use EXPORT to modify the environment variable to search for the 32bit libraries.

export LD_LIBRARY_PATH=/usr/local/lib/arm-linux-gnueabihf/

First check to see if the project actually sent you the armv7l application and check its permissions. Is is really there and is it executable.
The other possibility is that you will need to export the 32 bit libraries to userland for the application to see them.

The alt_platform statements will do nothing unless you also install the standard 32 bit libraries. Only if you have those installed will the scheduler determine you are eligible for the arm-unknown-linux-gnueabihf application and send you work.

[Edit]
At minimum do this:
dpkg --add-architecture armhf
apt-get update (ignore the missing x386 packages and hope for the best)
apt-get install libc6:armhf libstdc++6:armhf

Thanks. I have been at it for quite a while. Pre-BOINC back in the Seti Classic days and then with BOINC.

Three Billion credit projects so far and soon hope to add GPUGrid to the list in July.
