Thanks for the fast answer !
The error coming from MUMPS is :
On return from DMUMPS, INFOG(1)= -9
On return from DMUMPS, INFOG(2)=29088157
The matrix size : 4972410*4972410
I need only 1 eigen value, the one near zero.
In order to have more precision, i put ncv at 500.
I'm
Thank you. It is clear now.

I see.
Actually, my goal is to compile petsc without real MPI to use it with libmesh.
You are saying that PETSC_HAVE_MPI is not a sign that Petsc is built with MPI.
It means you have MPIUNI which is a serial code, but has an interface of MPI.
Correct?

Not sure why you are looking at this flag and interpreting it - PETSc code uses
the flag PETSC_HAVE_MPIUNI to check for a sequential build.
[this one states the module MPI similar to BLASLAPACK etc in configure is
enabled]

Let me explain the problem.
This log file has
#ifndef PETSC_HAVE_MPI
#define PETSC_HAVE_MPI 1
#endif
while I need to have PETSC without MPI.

Why it did not work then?

And I see from configure.log - you are using the correct option.

The option is --with-mpi=0
Are you getting an error from MUMPS or from BV? What is the error message you
get? What is the size of the matrix? How many eigenvalues do you need to
compute?
In principle you can use any KSP+PC, see section 3.4.1 of the users manual. If
you have a good preconditioner, then an alternative to
Hi all,
I'm trying to solve a huge generalize (unsymetric) eigen value problem
with SLEPc + MUMPS. We actually failed to allocate the requested memory
for MUMPS factorization (we tried BVVECS).
We would like to know if there is an alternate iterative way of solving
such problems.
Thank you,
Thanks for the fix. https://gitlab.com/petsc/petsc/pipelines/96957999

For a while I had put in an incorrect URL in the download location.
Perhaps you are using PETSc 3.12.0 and need to use 3.12.1 from
https://www.mcs.anl.gov/petsc/download/index.html
Otherwise please send configure.log
