gprMax supports parallelism through **MPI** and **OpenMP**. For a deeper dive into how parallelism works in gprMax, refer to the [official documentation](https://docs.gprmax.com/en/latest/openmp_mpi.html).

In this tutorial, you will learn how to configure and run gprMax simulations sequentially and using MPI. We will use the `B-scan with a bowtie antenna model` from the gprMax example cases as our demonstration.

This example creates a B-scan using an antenna model. The setup includes a metal cylinder with a diameter of 20 mm buried in a dielectric half-space with a relative permittivity of 6. The simulation uses an antenna similar to the GSSI 1.5 GHz antenna.

For a B-scan, the antenna must be repositioned for each A-scan (trace). In this case, the B-scan covers a distance of 270 mm with traces every 5 mm, resulting in **54 separate model runs**.
