description: Run gprMax simulations in parallel with MPI on Inductiva and cut runtimes from hours to minutes
---

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.
In this tutorial, you’ll configure and run gprMax simulations sequentially and with MPI, learning how to cut runtimes from hours to minutes with **Inductiva**.

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**.
