This paper describes the study and implementation of parallel algorithm and software for static buckling analysis.The research takes advantage of advanced serial finite element analysis code

MSC.NASTRAN as development platform

and massively parallel computer as parallel environment.The dominating computing work of elastic structure static buckling analysis was parallelized

and the parallel solver was implemented in Fortran90 and MPI.Moreover

the parallel solver was embedded into the original solution sequence as a sub-module

and could be called directly.For convenient use

the development for friendly interface was implemented.The integrated software

which includes serial pre-and postprocessors with parallel solver

can improve the scale and speed of linear buckling analysis for thin shell structure.
