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

In the below image, the currently computed part of the simulation grid (moving window) is marked as a hatched area. Note that for simulations which do not use moving window, the currently computed part of the simulation grid always spans the total simulation grid.

All wiki entries describe the dev branch. Features may be different in the current master branch.
