[petsc-dev] asm / gasm

[Mark Adams]

Barry,

I am having problems with your branch on ksp/ex56. First I was getting an
error with the increase of the overlap that you added (I don't want that to
be the default).  So I set this back to 0 in gamg.c.

Next, I get the same error with the vec out of range because ex56 has BCs
in the matrix.  I created a branch mark/fix-gamg-asm-aggs from your branch
and added the dummy ASM block. But I am getting all kinds of errors.  I get
errors in get MatSubMatrix and a funny error when it tries to free a prefix
string.

I've attached the valgrind output of one process, of 8.  There is a lot of
noise with string operations but it looks like the first non-string thing
is in MatGetSubMatrices.  ex56 is elasticity. Maybe there is a block size
problem?
