The problem

Scattering Particles

• Problem:
  A 1D domain is block decomposed. Each domain contains a different number of particles.Initially these all lie on one process. This process scatters the particles to the other processes.

  This example uses:

  mpi_scatterv (
     sendbuf, sendcounts, displs, sendtype,
     recvbuf, recvcount, recvtype, root, comm,
     ierr)
