Dear all, I am copying a distributed vector using the following function:
Vector <https://www.dealii.org/current/doxygen/deal.II/classVector.html> <Number>& Vector <https://www.dealii.org/current/doxygen/deal.II/classVector.html>< Number >::operator=(const PETScWrappers::VectorBase <https://www.dealii.org/current/doxygen/deal.II/classPETScWrappers_1_1VectorBase.html> & v) In the documentation it is written: "*Note that due to the communication model used in MPI, this operation can only succeed if all processes do it at the same time when v is a distributed vector: It is not possible for only one process to obtain a copy of a parallel vector while the other jobs do something else."* I would like to ask how can I synchronize all the processes to call the function operator() at the same time. Is there a barrier function or similar?
