Description
I need to solve a series of Ax=bi,i=1.....N with the matrix A unchanged.
while(time<FianalTime) { solve Ax=bi; set bi; if(time=SaveTime) copy x to cpu for further treating }
I want to know can i set the bi directly on the GPU without copying data between cpu and gpu.

Research direction
No files, tests, or entry points are named. Start by reviewing AMGX's repeated solve and right-hand-side handling, then determine whether b_i can remain on the GPU between solves and document the supported approach, including when x is copied to the CPU.
