Hi Folks!

We're back with another round of tasks. This time for Nvidia GPUs.

The first batch will have 262144 workunits (524288 tasks), but we anticipate that there will be far more in the future for this project fed in gradually. (Estimated 17.1 billion workunits possible).

Apologies for the lack of communication/delays the last few months. These days I'm the primary administrator on this project, and while I do pay attention to our discord more, I should do better to keep the community on the BOINC platform in the loop about future updates.

Beyond this project, we may have one other lined up (much smaller in scope than this 17.1 billion workunit project) and an overall platform upgrade that I've slowly been widdling away at these last few months as I find time.

I'll be pushing the new work tonight, so get your GPUs ready! They're available on Windows and Linux x86_64 machines.

Best Regards,

BoySanic

Yay. Best news I heard all year :)
Edit: Lots of debug info for you. No charge.

WOO HOO!!!!

Hey everyone,

A new version of this app (1.01) should be live now!

We're hoping this addresses many of the issues reported so far:

1. Linux segfaults
2. Windows access violations
3. Multi-GPU setups not working properly (assigning to one GPU rather than the one BOINC actually assigned).

This also includes some prints to the stderr.txt allowing us to read errors from the CUDA driver going forward. So any future issues should be easier to diagnose.

Happy crunching :)

What's the time line on amount of tasks/work units for this sub project? If you think you'll have enough work to last throughout 2025, I can add the project to BOINCGames competitions. If that's okay with the project admins.

The project just needs to have work to last the whole year.

Hi Folks,

For those of you getting that ptxas error, it's most likely because your Nvidia driver is out of date.

I compiled against CUDA 12.6 (roughly equating to driver 560+) but many of you don't seem to have installed Nvidia driver versions higher than 535.

That said, I did see driver 565 is available on Ubuntu 20.04.

Regardless, this is something we needed to have configured on our end to notify you via the client about this driver version minimum.

I'll update that shortly. Let me know if anyone sees any issues with updating your drivers.

Thanks!

From the OP in this thread from the dev "will be far more in the future for this project fed in gradually. (Estimated 17.1 billion workunits possible)."

Why don't you compile the app to cover a range of cards and driver versions?

Most hosts on Ubuntu 22 or 24 have default 535 drivers provided by the distros, that's why.

I posted over on the Number Crunching side of the forum, but wanted to post here as well that I'm shifting gears to recompiling the software to run on CUDA 12.2, which should be supported by driver 535 or above.

Thanks for your patience everyone!

Same here. Can't crunch anything. Please make it run on driver 535.

Hi everyone,

Thanks for your patience.

1.02 should be available running on CUDA 12.2 shortly. (Site is restarting as I type this).

Please let me know if there are any further computation issues.

Thanks!

Always compile to the minimum spec needed for the app to actually work. Requiring the absolute latest driver is ludacris.

My Win10 PC that crashed above is now running with 1.02
