you can also try lammps. check out

while lammps is a pretty bare bones MD code, you
can convert topologies generated with VMD/psfgen
to their native format and output dcd trajectory
files, so it is almost like using NAMD.

if you use only short range potentials, then LAMMPS
will parallelize quite well. at homogeneous, bulk,
plain LJ it is competitive to NAMD since there is
less load to balance and LAMMPS has a little less
overhead. for typical explicit solvent bio systems
with long-range coulomb NAMD is far better.
