Detailed Description

Distributed (MPI) flow validation driver — mirrors tests/kokkos_mpi/test_sdflow_mpi.cpp in Python.

Builds a GLOBAL 2x2x2 periodic sphere-packing SDF on every rank, uses peclet.flow.mpi_block(N,N,N) to
get this rank's ORB block, slices the local SDF, constructs Solver(*size), init_mpi(N,N,N), configures
rho/mu/dt/body-force, sets the local solid, runs STEPS steps, and reduces the global velocity sum via
mpi4py. The reduced permeability k = mu*<u>/F must be the SAME across np=1,2,4 (the distributed solve is
bit-exact to single-rank, to the MG-PCG reduction-order floor).

Run:
  PYTHONPATH=$PWD/build_mpi mpirun -np 1 ./.venv/bin/python scripts/verify_mpi_spheres_sdflow.py
  PYTHONPATH=$PWD/build_mpi mpirun -np 2 ./.venv/bin/python scripts/verify_mpi_spheres_sdflow.py
  PYTHONPATH=$PWD/build_mpi mpirun -np 4 ./.venv/bin/python scripts/verify_mpi_spheres_sdflow.py
