get_start_and_end_for_partitions[tile_size: Int](num_keys: Int, num_partitions: Int, partition_idx: Int) -> Tuple[Int, Int]
Calculate start and end indices for a partition.
Args:
- num_keys (
Int
): Total number of keys (sequence length). - num_partitions (
Int
): Number of partitions to split keys into. - partition_idx (
Int
): Index of current partition (0 to num_partitions-1).
Returns:
Tuple of (start_idx, end_idx) for the partition, aligned to tile_size.
