[Question] How cusparse APIs are used in AMGx

1

Can you please let us know how cusparse API are getting leveraged by AMGx. Specifically what configurations (condition/criteria) needs to be met in the code flow for AMGx to use...

AMGx currently supports Nvidia GPUs through CUDA. We want to contribute a new backend through Intel's oneAPI [SYCL](https://www.intel.com/content/www/us/en/develop/documentation/oneapi-programming-guide/top/oneapi-programming-model.html). This would enable support for Nvidia, AMD and Intel devices with a...

unsupported getri_batch/getrf_batch for Nvidia

As per the [oneMKL-LAPACK](https://github.com/oneapi-src/oneMKL/blob/develop/src/lapack/backends/cusolver/cusolver_batch.cpp) APIs "getri_batch/getrf_batch" are not implemented for Nvidia. void geqrf_batch(sycl::queue &queue, std::int64_t m, std::int64_t n, sycl::buffer &a, std::int64_t lda, std::int64_t stride_a, sycl::buffer &tau, std::int64_t stride_tau, std::int64_t batch_size,...

Query: QUDA Feature-SYCL branch
