LATTE: Los Alamos TravelTime package based on Eikonal equation
We develop an open-source package for traveltime computation, tomography and source location in 2D/3D isotropic acoustic/elastic media.
The work was supported by Los Alamos National Laboratory (LANL) Laboratory Directory Research and Development (LDRD) project 20240322ER. LANL is operated by Triad National Security, LLC, for the National Nuclear Security Administration (NNSA) of the U.S. Department of Energy (DOE) under Contract No. 89233218CNA000001. The research used high-performance computing resources provided by LANL's Institutional Computing program.
The work is under LANL open source approval reference O4770.
A manual will be released in the near future pending separate approval.
LATTE depends on FLIT. Some examples in example use RGM to generate random geological models.
The code is written in Fortran. Currently, it only support Intel's Fortran compiler, which is freely available through Intel oneAPI Base Toolkit and Intel HPC Toolkit. We tested LATTE with ifort 2021.10 and ifx 2024.2. The default compiler set by the Makefile for 2D and Makefile for 3D is ifx 2024.2 (the newest version of the compiler suite). Note that per Intel's announcement, ifort will be deprecated starting from late 2024.
To install LATTE,
cd src
ruby install.rb
The compiled LATTE executables will be at bin.
To remake,
cd src
ruby install.rb clean
We include several simple examples to use LATTE in example. To run the tests,
cd test
and the scripts to reproduce the examples in the mansucript are contained in subfolders.
