Function roofline_bounds 

pub fn roofline_bounds<R: Runtime>(
    client: &ComputeClient<R>,
    compute_key: ThroughputKey,
    work: Work,
    thresholds: Thresholds,
) -> Bounds

Calculates roofline autotune bounds for a given Work amount and compute throughput key.

Measures compute and memory peak throughputs along with launch overhead for the runtime client.
