Hi, I have a parallel vector spread across all processors that I would like to gather into a single processor, say the root processor. Is there PETSc functionality to do this? I tried looking for a PETSc gather function but the one I found, VecStrideGather <http://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/Vec/VecStrideGather.html>, does not seem to apply. Should I simply use the MPI routine MPI_Gather?
