WebThe energy of each particle equals a global constant k multiplied by the square of the distance between the particle’s current position (x, y, z) and a reference position (x0, y0, z0). We specify that x0, y0, and z0 are per-particle parameters, so each particle can have a different reference position. http://docs.openmm.org/latest/userguide/application.html

WebOpenMM utilizes both CUDA and OpenCL to program molecular models for GPUs, and runs the entire calculation on the accelerator device to eliminate the GPU-to-CPU communications that can significantly limit performance. In general, the CUDA platform is faster than the OpenCL platform, but OpenCL works on a much wider array of hardware.
