A no
David,
Depending on what you wish to do it may be very easy. The logging
is all done on a per process basis (each process just logs its stuff).
PetscLogPrintSummary() takes as an argument a communicator and summarizes
all the data over THAT communicator. So it may be as simple as calling
Pets
I would like to create two communicator subgroups of PETSC_COMM_WORLD.
Is it possible to use the petsc profiling utilities to profile the two
communicator sub-groups individually?
thank you,
David Fuentes

Hi,
I'm trying to plot using X a sparse matrix of order 100.000, with
about 7.000.000 not zero elements using
ierr = PetscViewerDrawOpen(PETSC_COMM_WORLD, NULL, "matrix ATA",
PETSC_DECIDE, PETSC_DECIDE, PETSC_DECIDE, PETSC_DECIDE, &atav

The code is not scalable for large matrices; I would argue that
it doesn't make sense to visualize such large matrices in this way.
Each matrix entry is tiny compared to a single pixal on the screen.
For PDE problems and most others, the non-zero structure of the
matrix is well represented wit
Yes, the implementation is very bad. It assembles the whole matrix on process 0
before viewing. It is intended for very small matrices only. Fixing would entail
rewriting the X viewer to take pieces of the matrix at a time. This is
a low priority for
us now, but we would gladly accept contributed c

Can you try the following change to python/BuildSystem/RDict.py - and
then run configure with the option '--useThreads=0' - and see if it
works?

No - its using the python - installed at

What version of redhat? What do you have for:
cat /etc/redhat-release
Ben,
First make sure that the residual has actually gotten
to the tolerance you want. PETSc KSP does NOT stop if the
linear system has not converged; you should call KSPGetConvergedReason()
after each solve to make sure it has converged (as a quick check
you can run with -ksp_converged_reaso
No, this sounds like a bug in the code. You probably are overwriting
memory somewhere.

Jianing,
There is no "by hand" in PETSc! All you do is acess the next
set of grid points to via the indices in the usual way. So
in two dimensions to access the values to the "left of x[j][0]
use x[j][-1] to the right of x[j][nx-1] use x[j][nx]. (Recall the
i,j indices are reversed in the C a
