The TREX Center of Excellence in Exascale Computing organises the "Bridging Quantum Monte Carlo and High-Performance Simulations" Symposium, took place from February 5 to 9, 2024, in Esch-sur-Alzette, Luxembourg. The symposium focuses on the latest developments in quantum Monte Carlo (QMC) methods, also in relation to high-performance computing (HPC). Topics covered include materials simulations with QMC, method developments, HPC implementations, machine learning for QMC, trans-correlated methods, and others. The event will also feature some practical demonstrations to showcase the progress of TREX codes and libraries, including QMCkl and TREXIO. This symposium is tailored for researchers, scientists, and professionals within the quantum chemistry and physics, materials science, and high-performance computing domains.
