For my tasks, I had some success with algebraic multigrid solvers as preconditioner, for example from AMGCL or PyAMG. They are also reasonably easy to get started with.

https://github.com/ddemidov/amgcl
But I only have to deal with positive definite systems, so YMMV.
I am not sure whether those libraries can deal with multiple right-hand sides, but most complexity is in the preconditioners anyway.

Xilinx made triSYCL (https://github.com/triSYCL/triSYCL), so maybe there's some chance AMD would invest in creating first-class support for SYCL (an open standard from Khronos). That'd be nice. But I don't have much hope in that regard.

OpenCL-Wrapper
OpenCL is the most powerful programming language ever created. Yet the OpenCL C++ bindings are cumbersome and the code overhead prevents many people from getting started. I created this lightweight OpenCL-Wrapper to greatly simplify OpenCL software development with C++ while keeping functionality and performance.
