MD
A Molecular Dynamics Program

MD is a program which simulates the behavior of a collection of N particles in a box, by computing their positions, velocities and accelerations at STEP_NUM regularly spaced times.

The program does some initialization, and then enters an integration loop. The results of each time step are summarized by printing the time, and the kinetic and potential energies (whose sum should be constant).

The main work occurs in the function update; most of the rest of the work is carried out in function compute.

Source Code:

• md.c, the C source code.
• md.cpp, the C++ source code.
• md.f, the FORTRAN77 source code.
• md.f90, the FORTRAN90 source code.

Completed Source Code:

Here are "completed" versions of the programs.
(Access to these files may be restricted until everyone has had a chance to work on the problems!)

• md_complete.c, the C source code.
• md_complete.cpp, the C++ source code.
• md_complete.f, the FORTRAN77 source code.
• md_complete.f90, the FORTRAN90 source code.

Script for Local Execution:

• md_local.sh, runs the program locally.
• md_local_output.txt, the output file.

Batch Script for the FSU HPC cluster:

• md_batch.sh, a script to submit to the batch system.
• md_batch_output.txt, the output file.
