Public Functions Documentation

function MPIDomainSplit

Constructor. 

inline TempLat::MPIDomainSplit::MPIDomainSplit (
    ptrdiff_t total,
    ptrdiff_t nDimensions,
    ptrdiff_t nDimensionsToSplit
)

Parameters:

  • total the number of processors in total in the group. Don't pass a prime number.
  • nDimensions the total number of the domain.
  • nDimensionsToSplit <= nDimensions, the number of factors which should multiply to total.
