You can also look into SLEPc to compute eigenvalues in parallel for the
global system.
SLEPc is based on PETSc so it should not be too hard to use in your code.

Hello,
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.
How should i go about this problem? can i use different
communicators or something? Please help!
Do you need all the eigenvalues? If so, you can try to use Elemental,
with the development version of PETSc.
Thanks,
Matt
