= GUARDYAN || GUARDYAN (GPU Assisted Reactor Dynamic Analysis) is a continuous energy Monte Carlo (MC) neutron transport code developed at Budapest University of Technology and Economics ([http://www.reak.bme.hu BME]). It targets to solve time-dependent problems related to fission reactors with the main focus on simulating and analyzing short transients. The key idea of GUARDYAN is a massively parallel execution structure making use of advanced programming possibilities available on CUDA (Compute Unified Device Architecture) enabled GPUs (Graphics Processing Units).\\ \\ * '''[wiki:GuarDyan_features Aims ]''' \\ * '''[wiki:GuarDyan_features Features ]''' \\ * '''[wiki:GuarDyan_features Physics Modelling and Verification ]''' \\ * '''[wiki:GuarDyan_features Variance Reduction ]''' \\ * '''[wiki:GuarDyan_features Examples ]''' \\ * '''[wiki:GuarDyan_features Publications ]''' \\ * '''[wiki:GuarDyan_features Project Participants and Funding ]''' \\ \\ [[Image(woodcock_elastic-scatter.3.png​, 600px, title=Neutron density distribution in the BME Training reactor calculated by GUARDYAN)]] \\ ''Fission source time evolution starting neutrons from point source at the centre '' || [[Image(BME_OR_1e-6s_n2e24_neutrondensity_Guardyan_v3r.jpg, 400px, title=Neutron density distribution in the BME Training reactor calculated by GUARDYAN)]] ''Neutron density distribution in the BME Training reactor calculated by GUARDYAN'' [http://www.reak.bme.hu/oktatoreaktor.html] Training Reactor|| ---- GUARDYAN (GPU Assisted Reactor Dynamic Analysis) fejlesztői segédlete [wiki:GuarDyan_fejlesztoi itt található].
