What is a roofline plot?
2 The Roofline Model. The roofline model is often represented as a two-dimensional plot with Performance (Flops/Cycle or Flops/s) in the Y-axis and operational (also known as arithmetic or numeric) intensity (Flops/Byte) in the X-axis, as depicted in Fig.
How do you analyze a roofline?
Key take-aways from these steps: The Roofline analysis is a combination of the Survey analysis followed immediately by the Trip Counts/FLOPs analysis….Run a Roofline Analysis
- Run a Roofline Analysis.
- Show/hide the Roofline chart.
- Get to know Roofline chart data.
- Get to know Roofline chart controls.
Why would you want to make a roofline plot?
The benefit of roofline plot is that they express the characteristic of the algorithm (Arithmetic Intensity) and the hardware (peak FLOPS and BW) in one graph, making it easy to see how to improve the performance of an algorithm and to compare the performance of different algorithms and hardware in the same plot.

What is roofline performance model?
The Roofline model is an intuitive visual performance model used to provide performance estimates of a given compute kernel or application running on multi-core, many-core, or accelerator processor architectures, by showing inherent hardware limitations, and potential benefit and priority of optimizations.

What is the bit under the gutter called?
The fascia board is the one mounted at the point where the roof meets the outer walls of the house and is often called the ROOFLINE. However most people refer to it by the name of the main board that carries the gutter – the fascia or fascias.
What is the roofline analysis and why is it useful?
Roofline analysis is a method to estimate performance with an eye on giving feedback about where bottlenecks exist. In other words, it guides us to where the full potential of the system isn’t being reached.
What is the wood under the roof called?
Also known as the wood sheathing, this is the base on which everything else is laid on. It’s essentially the foundation of the roof. This is typically made with OSB or oriented strand board or plywood that’s attached with nails onto the rafters.
What is the edge of the roof line called?
Eave: A roof edge that extends past the exterior wall line at the bottom of a slope. Fascia: Vertical roof trim located along the perimeter of a building, usually below the roof level, to cover the rafter tails at the eaves and to seal off the top of the siding along the rake; also called gutter boards.
What is GFLOPs performance?
Gigaflops is a unit of measurement used to measure the performance of a computer’s floating point unit, commonly referred to as the FPU. One gigaflops is one billion (1,000,000,000) FLOPS, or floating point operations, per second.
What is the trim under a roof called?
Fascia Fascia: Vertical roof trim located along the perimeter of a building, usually below the roof level, to cover the rafter tails at the eaves and to seal off the top of the siding along the rake; also called gutter boards.
What is the edging around the roof called?
Roof edge (or eaves edge) All the boards running along the edge of the roof or eaves. Also known as a fascia.
What are the components of a residential roof?
The Parts of a Residential Roofing System Surface. The topmost part of the roofing system is composed of the main roofing material. Underlayment. Because the surface is not perfectly waterproof, a residential roofing system needs a watertight layer just underneath the shingles. Sheathing. Flashing. Fascia. Soffit.
What is a residential roof?
Residential Roofing Products. Residential Roofing Products include those products necessary to provide a quality roofing system typically for a consumer’s home, garage or other residential applications. Residential roofing products are usually designed for steep slope application.
What are the parts of a roof truss?
The roof system consists of several very important parts: wall beams (or plates, sometimes described as a type of purlins) that run horizontally under the roof truss and connect it to walls; purlins, horizontal members connecting rafters; rafters, sloped parts of the truss running from the wall beams on both sides to a ridge board, which is a
What is edge of roof?
A roof overhang is called an eave. An eave is the edge of a roof that projects beyond the face of a wall, providing protection from the elements. Eaves are located at the bottom edges of a roof.
