Class AntiprotonSeq

java.lang.Object

edu.rit.clu.antimatter.AntiprotonSeq

public class AntiprotonSeq
extends java.lang.Object

Class AntiprotonSeq is a sequential program that calculates the positions of the antiprotons as a function of time. Each antiproton experiences a net repulsive force from all the other antiprotons. Each antiproton also experiences a force due to a magnetic field perpendicular to the plane in which the antiprotons move.

Usage: java edu.rit.clu.antimatter.AntiprotonSeq seed R dt steps snaps N outfile

The program:

1. Initializes a pseudorandom number generator with seed.
2. Generates N antiprotons positioned at random in the square from (0.25R,0.25R) to (0.75R,0.75R).
3. Sets each antiproton's initial velocity to 0.
4. Stores a snapshot of the antiprotons' initial positions in the outfile.
5. Performs steps time steps and stores another snapshot of the antiprotons' positions in the outfile. Each time step is dt.
6. Repeats Step 5 snaps times. The number of snapshots stored in the outfile is snaps+1.

The computation is performed sequentially in a single processor. The program measures the computation's running time. This establishes a benchmark for measuring the computation's running time on a parallel processor.
