Where to use OpenMP, MPI libraries?
Are the OpenMP or MPI libraries still up to date? If so, for what purposes are they used in practice?

These are two completely different technologies: Open Multi-Processing and Message Passing Interface.
The first helps to parallelize the execution of pieces of code on one machine without the explicit use of threads, the second - to perform work on a cluster.
gcc has an implementation of OpenMP, you can enable it with the -fopenmp flag and use OpenMP pragmas and functions.
I did not work with MPI, I will not tell.
