I would like to partition and read a mesh in parallel.
After reading the discussion on the mailing list on “pre-partitioning a big
mesh"
I used the splitter to partition the mesh. The partitioner just worked (that
was great! Thanks!).
I set up a simple test to check if I could read the mesh.
Partitioning with one processor and then reading it works fine.
On the other hand when I try with 2 processors I get the following error.
Assertion `mesh.comm().semiverify(p_my_neighbor)' failed.
/not_backed_up/srossi/TPL/libmesh/libmesh-git/src/mesh/mesh_tools.C, line 1726
My simple test looks like this:
#include "libmesh/parallel_mesh.h"
int main(int argc, char** argv)
{
using namespace libMesh;
LibMeshInit init (argc, argv, MPI_COMM_WORLD);
ParallelMesh mesh(init.comm());
mesh.read("LA_T4_new_m1.cpr");
mesh.print_info(std::cout);
return 0;
}
Do you have any suggestions?
Can you send me the original mesh? The Checkpoint I/O is currently in
a fragile state, and I'm working to fix that, but I've been chasing
down other red herrings (well, other significant issues that turn out
to be MOOSE- or libMesh-but-not-Checkpoint- related), and having such
a simple test case to work with would be a big help.
