    Abstract

    The work described in this paper forms the preliminary stages in an ongoing project to meet these objectives. The paper will look first at the implementation of eigensolution on muti-core computers using the subspace iteration method. Attention is given to software design aspects; execution speed; and using the methods to enhance usability. On the software engineering side, component oriented design is used. Parallelisation of the subspace iteration method is implemented using a beta version of the .NET Task parallel Library (TPL). The software is tested on two space trusses, with 1623 and 9831 degrees of freedom, with the code being run on a quad-core processor. Parallelisation of the subspace algorithm itself yielded a speed-up of 2.59 for the larger problem, whereas the domain decomposition version achieved 3.16.
