1. We will introduce the BEAST eigensolver, which incorporates both polynomial and contour integral type filter diagonalization schemes for the solution of large sparse eigenproblems. The solver incorporates multiple levels of parallelism as well as a variety of algorithmic advances for fast, accurate, and robust solution. The underlying filter diagonalization schemes and the resulting solver will be introduced here.
2. In this talk we will discuss some of the latest advances of the BEAST eigensolver, including the availability of mixed precision calculations for reduced calculation time while maintaining accuracy. We also show results from recent tests showing the scalability of BEAST to very large problem sizes and numbers of cores.
