// * length is max_num_tokens_padded, actual size is num_tokens_post_padded_ptr
//
// * Note on token_id_per_expert/sorted_token_ids_ptr data:
// currently we do not have topk information from the data of token_id_per_expert/sorted_token_ids_ptr.
// In some cases(like smooth-quant), we need topk information to indexing into tokens quant from
// different expert smooth quant. So we modify the number stored inside token_id_per_expert/sorted_token_ids_ptr
//
// 32bit 0........23 24.....31 bit
// (data) -> (token_id | topk_id)
// low 24 bit is for token id, top 8 bit is for topk id
//
// the input after smooth-quant is [token, topk, hidden_dim], originally it is [token, hidden_dim]
// the input scale for token is [topk, token, 1], the smooth-quant scale for first gemm is [expert, interm_dim]
//
// sorted_expert_ids_ptr : [0, 1, 2, 3, 3, 4, 5]
// * length is (max_num_tokens_padded + block_size - 1) / block_size
//
// num_tokens_post_padded_ptr : [28]
// num_sorted_tiles_ptr : [7]
//
// * different from vLLM
// 1) token_id stored in sorted_token_ids_ptr is actual token_id, not token_id*top_K expanded id
// 2need sorted_weight_ptr
// 3) use num_sorted_tiles_ptr, already divided by M_a
//
// * below used for indexing
// 1) sorted_token_ids_ptr [max_num_tokens_padded]
// 2) sorted_weight_ptr
// 3) sorted_expert_ids_ptr
// 4num_tokens_post_padded_ptr/num_sorted_tiles_ptr (select one)
//
// max_num_tokens_padded: opk_ids.numel() + num_experts * (block_size - 1)
//
// [indexing implementation-2]

// topk_weight is : [[a, b, c], [d, e, f], [g, h, i], [j, k, l], [m, n, o]] (some float number)
//
// we generate original rol/col id as
// topk_rc_ids : [[0, 5, A], [1, 6, B], [2, 7, C], [3, 8, D], [4, 9, E]]
// let x be one element of above, we can get:
// tpok_row_id(token_id) = x % num_tokens(5)
// tpok_col_id(expert_Id) = x / num_tokens
