[lammps-users] Large Gay-berne(.gb) or Lenard Jones(.lj) Input file

I am working on benchmarking LAMMPS on multiple GPUs.For that i need a large input file of the type gay berne(.gb) or lenard jones(.lj).Can any one tell me the place where to find a large input file or how to generate a large input file of the type .gb or .lj?

for the most part, you should have a look at the online documentation.

there are a set of benchmark examples in the lammps distribution for the
cpu that can be easily adapted for the gpu supported pair styles.
similarly, there is: http://lammps.sandia.gov/bench.html
which has examples for gay-berne and lennard-jones.

also there is:
http://sites.google.com/site/akohlmey/software/lammps-benchmarks
http://git.icms.temple.edu/git/?p=lammps-icms.git;a=tree;f=bench-nsf

that compare all-MPI, OpenMP+MPI and GPU+MPI runs of several
systems on a number of platforms.

axel.

The replicate command in LAMMPS will convert a small (periodic)
problem into a larger one. You can also just use the create_atoms
command to generate as large a lattice of particles as you like.
The set quat/random command will randomize ellipsoid orientations once
they are created.
