CUSPARSE preconditioner alternative

Accelerated Computing GPU-Accelerated Libraries

Hello.

It looks like cuSPARSE ILU0 preconditioner is deprecated and will be removed in CUDA 13.
But I don’t see any alternative routines.
Which library or routine should I use to replace deprecated functions?

Thanks.

We don’t currently plan to support ILU0 for the next release. We haven’t found strong enough use cases to invest significant engineering effort and resources on to maintain the feature. Nevertheless, there’s sufficient time before the next update, and we’re open to suggestions from the community.

It really depends on the use case. There are some good C++ libraries for CPU-only, while for GPU is less popular. My suggestion is to look at papers related to the topic that provide the code for this functionality.
