Target substance/model

Any molecular aggregates, especially molecules in nanotechnology and biotechnology disciplines, for example, solutions, micelles, lipid membranes, proteins, polymers, and viruses.

Physical quantities that can be computed

Orbitals, structures, and thermodynamic quantities such as free energy.


Molecular dynamics method


Parallel computing by MPI and OpenMP is supported. The number of processes for MPI parallel computing is restricted to 2^n (n: positive integer) in the latest version released on the Web. The number of threads for OpenMP parallel computing is arbitrary.

Parallel computing by GPGPU is supported at the level of OpenACC in a development version, which has not been released yet.

Parallel computation using Xeon-Phi is being developed (supported as a JHPCN project).

This package includes various methods required for the molecular dynamics calculation of materials in nanotechnology and biotechnology. Highly efficient massively parallel computing is possible, and extended simulation is possible for systems comprising tens of thousands of atoms up to around 10 million atoms. The software can also calculate free energy.
