Computational Relativistic Astrophysics studies regions of the universe where gravity is very strong, and space-time geometry is distorted. This includes objects such as black holes, neutron stars,or core-collapse supernova explosions. High performance computing uses the world's largest computing systems as a laboratory, predicting and visualizing the behaviour of these systems that are extremely difficult to observe directly.
I will introduce some modern methods and tools that map complex systems of equations (such as the Einstein equations) onto modern computing architectures. I will then report recent results of simulations of potential engines for Gamma-Ray Bursts, the most energetic electromagnetic events in today's universe.
