First Attempt

• Unfortunately this doesn’t help with get_data()

  • different types: two floats and one int
  • not guaranteed to be contiguous in memory

• Idea: use a C structure

Typedef struct {

float a;

float b;

int n;} INDATA_T;

INDATA_T indata;

MPI_BCAST(&indata, 1, INDATA_T, 0, MPI_COMM_WORLD);

• WRONG! Arguments to functions must be variables not defined types
