cusparseZcsrcolor - deprecated

Accelerated Computing GPU-Accelerated Libraries

Hi,

We use cusparseZcsrcolor in an algebraic multigrid solver. The function has been marked as deprecated. Will it be replaced with an alternative?

Thanks for any feedback,

Best Regards,

Andrea

Hi @andrea_nes. We don’t have an alternative for cusparseZcsrcolor at the moment. We won’t remove the function until we have a replacement for it.
Thank you for letting us know you’re using the csrcolor functionality. Would you mind sharing with us your use case: What’s your application? What computation benefits from cusrcolor routine?

Hi,

Thank you for your response, and glad to learn that functionality will not disappear.

I am glad to provide feedback regarding the use of those routines, but I cannot detail exactly the use in a public forum. Can you please provide an email where I can write (I can be contacted at aborsic@ne-scientific.com)

Thanks and Best Regards,

Andrea

Hi,

I would like just to leave some feedback: we use that function in an AMG solver.

The final application is to simulate in real-time several types of physics taking place during different surgical procedures - to provide intraoperative surgical guidance functions. Our products have been licensed to multiple medical device manufacturers.

Best Regards,

Andrea

Hi. Thanks for sharing the information of your work with us.
As an alternative, you can check cuGraph’s graph coloring utility: cugraph/cpp/include/cugraph/algorithms.hpp at branch-25.04 · rapidsai/cugraph · GitHub. We haven’t compared the performance of cuGraph and cusparseZcsrcolor; so, I’m curious if it’s suitable to your application.

Thank you, we will consider this, and have a look at cuGraph
