Execution Methods#
Execution methods are used to run the Solver function as defined by user with cuSolverDx operators.
Note
Right now, cuSolverDx supports only execution on CUDA thread block level (block execution).
Block Execute Methods#
The block execution methods are available if the descriptor has been constructed using the Block Operator
and is_complete_solver_execution Trait is true. All threads within a block must collectively participate in a block execution method; otherwise, the behavior is undefined.
execute(...) runs the calculations defined by the Solver descriptor, and its arguments vary depending on the descriptor’s function.
