OPALp

Energy refinement and molecular dynamics simulation algorithm for biomolecules

OPALp is a program for molecular dynamics (MD) simulation and energy refinement of biological macromolecules. OPALp features point-centered domain decomposition, a new algorithm for MD simulations on parallel computers that can make efficient use of up to 100 and more processors for realistic systems of a protein in water comprising 10 000 to 20 000 atoms. The implementation in OPALp uses a standard message passing library, so that the program runs on both shared memory and massively parallel distributed memory computers.

Availability

• Development and support for OPALp has been stopped. The program is currently not available.
