int QudaInvertParam_s::use_sloppy_partial_accumulator

Whether to keep the partial solution accumuator in sloppy precision This parameter determines how often we accumulate into the solution vector from the direction vectors in the solver. E.g., running with solution_accumulator_pipeline = 4, means we will update the solution vector every four iterations using the direction vectors from the prior four iterations. This increases performance of mixed-precision solvers since it means less high-precision vector round-trip memory travel, but requires more low-precision memory allocation.
