[Trilinos-Users] Get all eigenpairs

[Baker, Christopher G.]

Hello.

Not easily. For parallel dense eigenvalue solves, your best bet is SCALAPACK. Trilinos does not have an interface to SCALAPACK. There are parallel eigensolvers appropriate for finding some eigenvalue of a sparse or matrix-free operator (namely, in the package Anasazi). However, in general, it is difficult to extend these to compute all eigenvalues, and there is no specific support for this in Anasazi.

Good afternoon,

Is It possible calculate paralleling all eingenpairs of a dense (or sparse) symmetric matrix by Trillinos?

Thanks.
