  We developed a portable code for dissipative particle dynamics (DPD)
simulations. This Fortran program named CAMUS has a couple of notable features.
One is the omission of constructing the so-called neighboring particles list,
providing a sizable speed-up per step and also a near linear scaling of costs
with respect to the number of particles. The other is an easy inclusion of
additional specific (such as 1-3 and 1-5 Morse bonding) interactions which are
crucial in describing protein structures. The formations of alpha-helix and
beta-sheet through DPD were then demonstrated. CAMUS is freely available at the
GitHub site.
