# FN_PARALLEL_SYNCHRONIZED

In matrix function evaluation, only the first MPI process performs the computation.

## Note

When this parallel mode is selected, only the first MPI process performs the computation and then the computed matrix is broadcast to the other processes in the communicator. This communication is done automatically at the end of `FNEvaluateFunctionMat()` or `FNEvaluateFunctionMatVec()`.
