Many Julia package names end with `.jl`. This is just a way of signaling that a package is written in Julia. When using such packages, the `.jl` needs to be omitted. In this case, we have isntalled the `MPI.jl` package even though we have only typed `MPI` in the REPL. Many Julia package names end with `.jl`.

The package you have installed it is the Julia interface to MPI, called `MPI.jl`. Note that it is not a MPI library by itself. It is just a thin wrapper between MPI and Julia. To use this interface, you need an actual MPI library installed in your system such as OpenMPI or MPICH. Julia downloads and installs a MPI library for you, but it is also possible to use a MPI library already available in your system. This is useful, e.g., when running on HPC clusters. See the documentation of `MPI.jl` for further details. The package you have installed it is the Julia interface to MPI, called `MPI.jl`. Note that it is not a MPI library by itself.
