MPI TypeMap Display

Little library allowing to display Typemaps for derived Datatypes in MPI.

Quick documentation

Use #include <typemap.h> to access the function void printMapDatatype(MPI_Datatype datatype). The typemap is printed on the stdout.

  • [ means that this is the beginning of and vector typemap. ] is for the end of it.
  • < and > are for an indexed.
  • { and } are for a structure.

Output example :

"(LB, -3), (MPI_INT, 0), (MPI_INT, 9), (UB, 15)"
