PeIGS parallel eigensolver library
The PeIGS library contains subroutines for solving standard and generalized real symmetric eigensystems. All eigenvalues and eigenvectors can be computed.
PeIGS incorporates scalable
- data structures: compact storage, column distribution with panel-block computation; and
- algorithms including inverse iteration with repeated reorthogonalization.
The library is implemented using message-passing model and is portable across many platforms.
