In this paper, an extended divide and conquer algorithm is intended proposed, which is for solving the real symmetric band generalized eigenvalue problem under distributing environment Eigenvalue partition theorem is presented and proved Based on divide and conquer by extension, this algorithm computes generalized eigenpaires of symmetric band matrix pencil by bisection and generalized Rayleigh quotient iteration Theoretic analysis and numerical results show that this algorithm is better than the classic software package LAPACK when bandwidth is small and the scale is large Combined with multisection, which has good parallelism, it got good effects under distributed environments

Then according to the cascade of IPS and LPS, the multi-stage rearrangeable nonblocking Omega network was introduced. Moreover, the method of bipartition graph was adopted to ascertain the node state of each stage. At last, a module of the rearrangeable nonblocking Omega network, which was integrated with polarizing beam-splitter,λ/2 wave plate and perfect shuffle Plates, was constructed.

该方法通过逆混洗(Inverse Perfect Shuffle， IPS)和左混洗(Lott Perfect Shuffle， LPS)的串联，构成多级的可重排、无阻塞的Omega网络，采用二分图法依次确定各级节点开关的状态，最后通过偏振分光棱镜(Polarizing Beam Splitter， PBS)、半波片(λ/2 wave plate)和PS Plate的组合，得到可重排、无阻塞的Omega网络交换模块。
