Outline Monte Carlo Method Implementation of photon transport Input Data Compare CPU’s Output&GPU’s Result
Monte Carlo Method Step 1: Create a parametric model, y = f(x 1, x 2,..., x q ). Step 2: Generate a set of random inputs, x i1, x i2,..., x iq. Step 3: Evaluate the model and store the results as y i. Step 4: Repeat steps 2 and 3 for i = 1 to n. Step 5: Analyze the results using histograms, summary statistics, confidence intervals, etc.
