[petsc-users] Issue about using MUMPS with PETSc

[Gavin Ge]

Hi Satish:

Yes I used to use metis. But this update require a cmake 2.5 or higher, which I don't have a privilege to install on the cluster.. But I think you are right, this problem could be fixed by install metis instead. Thanks!

Gavin
