We describe a matrix multiply based block unsymmetric inverse iteration solver for upper Hessenberg matrices. Our kernel is robust in that it prevents overflow by scaling. It uses new techniques to ensure performance is not sacrificed when scaling is not necessary. Finally, we give results on a parallel implementation on an Intel Paragon{trademark} supercomputer.
