Parallel Hybrid Simulations of Block Copolymer Nanocomposites using Coarray Fortran

Computer simulations of experimentally comparable system sizes in soft matter often require considerable elapsed times. The use many cores can reduce the needed time, ideally proportionally to number processors. In this paper a parallel computational method using coarray Fortran is implemented and tested for large systems purely block copolymer melts, as well nanocomposites. A satisfactory strong scaling shown up 512 while weak with drop performance achieved 4096 cores. cell dynamic scheme displays no drawbacks over MPI provides an example simplicity approach. code has been on several architectures compilers. hybrid copolymer/nanoparticle algorithm achieve previously unavailable sizes.
