SLEPc is based on PETSc so it should not be too hard to use in
your code.<br>

<div style="font-family:georgia,serif">I want to execute
Monte Carlo simulations for eigenvalue problem in
parallel with PETSC. i am using LAPACKsygvx function
to compute all the eigenvalues. Now the problem i am
facing is that, i think LAPACKsygvx requires Matrices
to be declared as MATSEQDENSE, and this sequential
type is not allowing me to execute this program on
multiple processors. <br>

<div>Do you need all the eigenvalues? If so, you can try to
use Elemental, with the development version of PETSc.</div>
