The most plugins currently not take care that only n-1 gpus (VirtualWindow) are analyzed in y direction. There is an open issue [1] for that. The hdf5 and adios output take care of the reduction in y direction and dumps out only the areas inside VirtualWindow. best regards, René [1] https://github.com/ComputationalRadiationPhysics/picongpu/issues/89 On 11/01/2016 10:59 AM, Khikhlukha Danila wrote: > Dear all, > > The moving window concept is described on this page: > https://github.com/ComputationalRadiationPhysics/picongpu/wiki/PIConGPU-domain-definitions#moving-window. > It is said there that the y-size of the domain if reduced by 1 GPU.
