CUDA 13 support

[Kaufmann, Steve]

Do you guys have CUDA 13 support (or at least building with it) anywhere on your radar? I noticed that a number of cuda API calls have changed.

Hello Steve,

The machines we currently have access to do not have the correct driver versions for Cuda Toolkit 13 nor is it installed. I have gone ahead and sent a message to the sysadmins in regards to updating the drivers and installing Cuda Toolkit 13 such that we can test.

You mentioned that a number of the Cuda API calls have changed. Did you configure and build PAPI with Cuda Toolkit 13 which resulted in compilation errors?

Best wishes,

Treece

Actually, I just did a compilation of the cuda component with cuda 13 headers and there were no compilations errors, so I guess that is good! So at least the signatures for the cuda calls made by the component have not changed. The only question is are there certain C marcos (such as #define some-value) that have changed in 13 vs 12 or did nvidia make an effort to keep backward compatibility in this regard.

Then there is the issue of runtime, of course.

I can set aside the cuda-13.0.0 installation tree in the cloud if you want to get at it (too large to attach it to the email).

Thanks, Steve

Hello Steve,

I just tested Cuda Toolkit 13 with Driver Version 580.65.06 on a machine with 8 * V100s. For myself:

• PAPI compiles and builds successfully with the cuda component configured
• The cuda component tests all pass
• The papi utilities: papi_component_avail, papi_native_avail, and papi_command_line all run successfully

However, please let me know if you run into any issues.

Best wishes,

Treece

Thanks Treece! That's good to know.
