Abstract: "The execution time of a symmetric eigendecomposition depends upon the application, the algorithm, the implementation, and the computer. Symmetric eigensolvers are used in a variety of applications, and the requirements of the eigensolver vary from application to application. Many different algorithms can be used to perform a symmetric eigendecompostion [sic], each with differing computational properties. Different implementations of the same algorithm may also have greatly differing computational properties. The computer on which the eigensolver is run not only affects execution time but may favor certain algorithms and implementations over others. This thesis explains the performance of the ScaLAPACK symmetric eigensolver, the algorithms that it uses, and other important algorithms for solving the symmetric eigenproblem on today's fastest computers. We offer advice on how to pick the best eigensolver for particular situations and propose a design for the next ScaLAPACK symmetric eigensolver which will offer greater flexibility and 50% better performance."

ScaLAPACK is an acronym for Scalable Linear Algebra Package or Scalable LAPACK. It is a library of high-performance linear algebra routines for distributed memory message-passing MIMD computers and networks of workstations supporting parallel virtual machine (PVM) and/or message passing interface (MPI). It is a continuation of the LAPACK project, which designed and produced analogous software for workstations, vector supercomputers, and shared memory parallel computers. Both libraries contain routines for solving systems of linear equations, least squares problems, and eigenvalue problems. The goals of both projects are efficiency, scalability, reliability, portability, flexibility, and ease of use.

This book provides state-of-the-art and interdisciplinary topics on solving matrix eigenvalue problems, particularly by using recent petascale and upcoming post-petascale supercomputers. It gathers selected topics presented at the International Workshops on Eigenvalue Problems: Algorithms; Software and Applications, in Petascale Computing (EPASA2014 and EPASA2015), which brought together leading researchers working on the numerical solution of matrix eigenvalue problems to discuss and exchange ideas – and in so doing helped to create a community for researchers in eigenvalue problems. The topics presented in the book, including novel numerical algorithms, high-performance implementation techniques, software developments and sample applications, will contribute to various fields that involve solving large-scale eigenvalue problems.
