Context

The first detection of a gravitational wave was in 2015 by the LIGO collaboration. This detection changed and expanded our perception of the universe. This discovery required a multidisciplinary effort that combines highly precise interferometers and data analysis tools. Such analyses require very precise modeling of the expected signals, given the high sensitivity required.

To date, LIGO-Virgo has detected around 90 collisions of black holes. In the next few years, it is expected that this number will grow very rapidly, along with the need to model these events and other possible sources of gravitational radiation. The most detailed description of black hole collision is provided by numerical simulation of Einstein’s equations. Given the high complexity of this task, specialized algorithms are required that can only be carried out using HPC. This research area has matured enough, and there is open-source software available that provides the necessary tools to perform these simulations.

Infrastructure

The event is supported by the National Laboratory for High Performance Computing (NLHPC), which will provide computer infrastructure as well as as well as specialized advice to help our instructors conduct both theoretical and practical sessions. During the event, individual accounts will be created for the participants so they can install and use the Einstein Toolkit software more efficiently. It is worth noting that the Einstein Toolkit is an open-source software platform designed to provide computational tools for research in relativistic astrophysics and gravitational physics and to take advantage of advanced cyberinfrastructure in Chile.

This event uses resources and services provided by the National Laboratory for High Performance Computing (NLHPC).
