Hi petsc-users, What solvers (either petsc-native or external packages) are available for quad precision (i.e. __float128) computations? I am dealing with a large (1e6 x 1e6), sparse, complex-valued, non-hermitian, and non-symmetric generalized eigenvalue problem. So far I have been using mumps (Krylov-Schur) with double precision but I'd like to have an idea about the rounding off errors I might be incurring.
Thanks in advance for any comments! Cheers, Andres.
