Query: GALAMOST: GPU-accelerated large-scale molecular simulation toolkit   A new molecular simulation toolkit composed of some lately developed force
fields and specified models is presented to study the self-assembly, phase
transition, and other properties of polymeric systems at mesoscopic scale by
utilizing the computational power of GPUs. In addition, the hierarchical
self-assembly of soft anisotropic particles and the problems related to
polymerization can be studied by corresponding models included in this toolkit.
