Will the Normal Kernel (dispatch kernel) exclusively occupy the SM of the GPU?

In the dispatch definition, each block has 512 threads. During actual execution, can we ensure that each block of the dispatch kernel exclusively occupies one SM through resource constraints such as register limits?

Start with the dispatch definition and its 512-thread block configuration, then trace the resource constraints relevant to SM occupancy. Done means documenting whether exclusive one-block-per-SM occupancy can be guaranteed and identifying the constraints or verification needed.
