I tried to sent a double vector with size of 5 to all other cpus.
but it seems no values have been broadcase out.
only the root has values in tt vector. all other cpus only have zero values
in tt.
Could you please help me out.
vector<double> tt(5);
if(Utilities::MPI::this_mpi_process(mpi_communicator)==0) {
for(int i=0;i<tt.size();i++) tt[i]=1.0*i;}
Utilities::MPI::broadcast(mpi_communicator,tt);
