I forward to Francois Pellegrini.
We take a look on that problem tomorrow, but I think you can
automatically remove the metis files from scotch in PETSc without
problems. Scotch uses them only to provide to users the Metis and
ParMetis interface with the libraries libscotchmetis.a and
libscotc

Thanks for the suggestion, when PETSc installs Scotch it

How is something other than ADD_VALUES necessary for BDDC? Onc
Scotch has a file called metis.h this is a big problem when
automatic installers are installing both ParMetis and Scotch since
automatic installers are not smart enough to read header file notes
and figure out exactly what file to delete. I would have reported this
as a bug to Scotch b

What most experimenters take for granted before they begin their experiments
is infinitely more interesting than any results to which their experiments
lead.

Sorry for jumping in late.
PDE discretizations and solvers many geometric decompositions of the
linear space
they ultimately operate on. However, many of these decompositions can
be expressed
rather naturally in linear algebraic terms (e.g., "factorization" of
the stiffness matrix into
a "sum" of
