Particle collision simulation

1.Introduction:

  • This project is a high-performance simulation of molecule collision in a box.
  • It is used to simulate collision of about 1000-10000 particles with density of 0.7-0.9 throughout 1000 steps.
  • Parallel computing techniques are applied (using OpenMP in particular) to optimize the runtime about 10 times faster than sequential implement.

2.How to run:

Compile:

Run the following command to compile the code:

make

Run the Simulation:

After compiling, run:

./sim <test> <number_of_threads>
  • <test>: Input file (initialize the molecule) (e.g: test/100k_density_0.9_fixed.in)
  • ``<number_of_threads> : Number of threads used to run simulation.
