spare linear solver on multiple GPUs

Hi Everyone,
I am a newbie to MAGMA. I am looking for a spare matrix iterative linear solver which can be run on multiple AMD type GPUs (supporting OPENCL). I have solved the same problem on Navida GPUs with AMGX library. I wonder does MAGMA allow using multiple GPUs for solving a spare matrix linear equations. Thank you.

The main focus of MAGMA is dense linear algebra, providing LAPACK for GPUs. MAGMA has also a sparse iterative solvers component but current support there is for single GPU only. There is a hipMAGMA port of MAGMA for AMD GPUs that ports CUDA to HIP.
