HotSpot is a widely used tool to estimate processor temperature based on an architectural floorplan and simulated power measurements. The thermal simulation iteratively solves a series of differential equations for block. Each output cell in the computational grid represents the average temperature value of the corresponding area of the chip. Our CUDA implementation re-implements the transient thermal differential equation solver from HotSpot. For more details about HotSpot, please refer to the article:
