Processing of the molecular dynamics model by the parallel computer pax

Molecular dynamics model is processed by a parallel array type computer PAX, that has an architecture of nearest neighbor meash connection of processors. Two parallel schemes, named Lagrangian and Eulerian, are implemented, execution time and efficiency are analyzed and expressed in terms of the basic parameters such as problem size and array size. The Lagrangian scheme realizes high efficiency close to 1, which assures the linear speedup proportional to the size of the processor array. Parallel programming technique is also presented.
