Class PiSmp

java.lang.Object

edu.rit.smp.monte.PiSmp

public class PiSmp
extends java.lang.Object

Class PiSmp is an SMP parallel program that calculates an approximate value for π using a Monte Carlo technique. The program generates a number of random points in the unit square (0,0) to (1,1) and counts how many of them lie within a circle of radius 1 centered at the origin. The fraction of the points within the circle is approximately π/4.

Usage: java -Dpj.nt=K edu.rit.smp.monte.PiSmp seed N
K = Number of parallel threads
seed = Random seed
N = Number of random points

The computation is performed in parallel in multiple threads. All threads share the same pseudorandom number generator and counter. The program measures the computation's running time.
