This is the beta version of the POLARIS(MD) website that is still under construction.
POLARIS(MD) is a molecular dynamics code developed at the Commissariat à l’Energie Atomique (CEA, France) which supports polarizable force fields (based on the point induced dipole approach), the TCPE class of short range many body potential energy functions, and a polarizable coarse grained approach can be oupled to standard or polarizable molecular force fields. It is supported by the Exascale Computing Research Laboratory (ECR).
Most of the POLARIS(MD) code have been vectorized and all the routines are multi-threaded (according to the OPENMP 4.0 standard). An MPI scheme to perform multiple independent simulations (e.g., to compute free energy or potential of mean force based on the Umbrella Sampling approach) is available. For large systems, a specific domain-based MPI scheme for our Fast Multipole Method has been introduced to perform massively parallel computations when using our coarse grained solvent approach in conjunction with a polarizable force field.
For a more detailed discussion of the methods used by POLARIS(MD), please see the Theory section of this website.
