Barry,
Thanks! Would you mind adding this to the manual?
A minor comment: even though -log_view :filename:format *is*
mentioned, supported formats are not documented in the PetscLogView
manual page.

It saves information from each process in one file in Python so it is easy
to process the summaries you want.

Dear All,
I have to parallelize an old fortran77-fortran90 cfd scalar code. Before
starting from scratch, I decided to parallelize “just” the pressure solver (for
instance a linear system solver A*x=q).
Because of the subroutines call tree, and in particular for the fact a lot of
subroutines are
Hello PETSc developers,
Is there a way to get profiling stats similar to -log_summary, but in
a format that can be processed programmatically?
As far as I can tell, current -log_summary output is tricky to parse:
whether output is space-separated depends on values that are printed.

Dear all,
I am solving a generalised eigenvalue problem
S \cdot v = a M \cdot v (1)
using Krylov-Schur eigensolver with the shift-and-invert transformation.
Now I would like to expand the problem to the case
[S + c^\ast \otimes c ] \cdot v = a M \cdot v (2),
where “c” is s

It may not. Cholesky generally just chugs along “pushing” the zero pivot to

Not necessarily. There are plenty of factorizable indefinite systems. Here
is one: an upper tr
But if it is indefinite, shouldn't the factorization algorithm complain about a

Hi,
I am having a convergence problem in a nonlinear FE problem (we only use ksp
from petsc, not snes). We don't have any problems using a direct solver with a
cholesky factorization (Petsc factor, cholmod, mumps). Now we want to solve it
using the bddc preconditioner. No problems on some prob
