Datatype Constructors (cont)<br />
MPI_TYPE_CREATE_HINDEXED (count, blocklengths, displs,<br />
oldtype, newtype, ierr)<br />
Identical to MPI_TYPE_INDEXED except displacements are in bytes<br />
rather then elements<br />
Displs are <strong>of</strong> type MPI_Aint in C and<br />
integer(KIND=MPI_ADDRESS_KIND) in Fortran<br />
MPI_TYPE_CREATE_STRUCT (count, lengths, displs, types,<br />
newtype, ierr)<br />
› Used mainly for sending arrays <strong>of</strong> structures<br />
› count is number <strong>of</strong> fields in the structure<br />
› lengths is number <strong>of</strong> elements in each field<br />
› displs should be calculated (portability) and are <strong>of</strong> type MPI_Aint in<br />
C and integer(KIND=MPI_ADDRESS_KIND) in Fortran<br />
