This library computes adjoint-state traveltime tomography in a very efficient way, by applying eikonal equation-based solver + multilayers MPI/SIMD parallelization.
Begin your journey with TomoATT: installation, documentation, and tutorials.
Explore TomoATT's scientific impact and performance on modern HPCs.
TomoATT supports multiple types of seismic data for any scale of projects.
TomoATT is designed for running on any size of computing resources with sophisticated mpi parallelization scheme, from a single laptop to a large HPC system.
The input/output file formats are designed to be easy to use. No post-processing is required for visualization of results.
In the core Eikonal solver, user can choose a suitable sweeping algorithm from the multiple options. A Higher-order stencil and parallelizable node ordering with SIMD optimization are also available.
Both local and teleseismic seismic events are supported, and even mixed datatypes can be used in a single tomography calculation. Absolute traveltime, common-source and common-receiver double difference traveltime data can also be used as the traveltime dataset.
Your new idea can be easily implemented in TomoATT's well structured code base.
