For results send by separate socket connections from each processor, the
parallel format just adds a prefix specifying the total number of processors and the current processor id:

An example of this can be found [here](https://github.com/mfem/mfem/blob/v4.8/examples/ex1p.cpp#L305).

To illustrate the parallel visualization capabilities of GLVis, suppose that we have solves a simple Poisson problem on a 2x2 square grid using 2 processors.
