This page describes the internal naming scheme for domain offsets and sizes in PIConGPU. (Names and semantics are subject to change)

domainSize: size of the simulation grid for a GPU
domainOffset: offset of the simulation grid of a GPU within the total simulation grid
globalDomainSize: size of the currently computed part of the simulation grid (moving window)
globalDomainOffset: offset of the currently computed part of the simulation grid (moving window) within the total simulation grid
localDomainOffset: offset of the simulation grid of a GPU from the start of the currently computed part (moving window). 0 for all GPUs for which domainOffset > globalDomainOffset
