John,
My first suggestion would be to use the petsc already built for Intrepid if
that is an option.
Either way, others have had luck using the local disks on the FEN to speed

Jed,
We replaced old numerical factorization and MatSolve with faster data structure,
then cleaned up MatPivotCheck() (still using previous algorithm).
Changes, such as

Jed,
I recall that I fixed bug in Kernel_A_gets_inverse_A_x(), e.g.
petsc-release-3.1:
Kernel_A_gets_inverse_A_4()
...
shift = .25*shift*(PetscAbsScalar(a[0]) + PetscAbsScalar(a[5]) +
PetscAbsScalar(a[10]) + PetscAbsScalar(a[15]));
petsc-dev:
shift = .25*shift*(1.e-12 + PetscAbsScalar(a[0]) +
PETSc never assumes that standards are followed nor that system implementors
are intelligent or even sane. Whenever something becomes system dependent (even
if the dependence is only because the system developer is insane) PETSc needs a
configure test for it. In theory adding new configure

With the version from Feb 1, I get (using AIJ since SBAIJ had no shift logic
at that time and just proceeded with negative pivots):

shift_amount 1.02086e+06
