Are you sure it works for broadcast? I tried this test code:
#include "libmesh/libmesh.h"
#include "libmesh/point.h"
#include "libmesh/parallel.h"
using namespace libMesh;
int main (int argc, char** argv)
{
LibMeshInit init(argc, argv);
// Let's try to broadcast a libMesh Point
Point p;
// Initialize p only on processor 0
if (init.comm().rank() == 0)
p(0) = 42;
Parallel::broadcast(p);
return 0;
}
and got a similar error:
parallel_implementation.h:2986:26: error: calling a private
constructor of class 'libMesh::Parallel::StandardType<libMesh::Point>'
MPI_Bcast (&data, 1, StandardType<T>(&data), root_id, this->get());
