Function analyse 

pub fn analyse(
    graph: &ComputeGraph,
    max_streams: usize,
) -> GraphResult<StreamPlan>

Runs the stream partitioning pass.

• max_streams — upper bound on the number of streams to create. Passing 1 disables parallelism (all nodes on stream 0). Passing 0 is treated as 1.

Errors

Returns GraphError::EmptyGraph if there are no nodes. Returns GraphError::StreamPartitioningFailed on internal errors.
