Finite　element　method,　as　one　of　calculation　methods,　has　been　widely　applied　in　numerical　solution　of　differential　equations,　engineering　structural　analysis,　and　electromagnetic　analysis,　etc.　When　solving　large-scale,　dynamic　loading　of　engineering　structures,　it　is　computationally　challenging　to　find　the　large-scale　nonlinear　equations.　A　parallel　implementation　of　nonlinear　equation　solver,　using　a　combination　of　MPI　and　OpenMP,　has　been　developed　in　OpenSees　which　is　an　open　source　finite　element　analysis　software.　It　shows　good　performance　to　apply　this　new　solver　to　analyze　the　scale　of　tens　of　thousands　of　equations　order.　Furthermore,　the　HPCToolkit　parallel　program　performance　analysis　tool　is　used　to　analyze　the　experimental　results,　Statistics　show　that　the　hybrid　parallel　programming　model　is　more　efficient　than　the　one　using　pure　MPI　in　the　multi-core　cluster　architecture　computing　environment.　©　2011　IEEE.
