Hallo Barry,
I think you're right, but this is the setup I used for more than a year,
so I first want to check if there is an error in my code and then switch
with an correct code to a newer version when I do have the time for the
installation.
Is the faster symbolic MatAXPY for the DIFFEREN
Hallo Matthew,
here is a short example I used for 8 cores:
int d_nnz[3];
int o_nnz[3];
d_nnz[0] = 3; d_nnz[1] = 3; d_nnz[2] = 3;
o_nnz[0] = 6; o_nnz[1] = 6; o_nnz[2] = 6;
ierr = MatCreateBAIJ(PETSC_COMM_WORLD, 3, 9, 9, 72, 72, 0, d_nnz,
0, o_nnz,&A);
ierr = MatSetOption
Klaus,
You would really benefit by upgrading to PETSc 3.5.3, we added much faster
symbolic MatAXPY() for the DIFFERENT_NONZERO_STRUCTURE flag. Plus it is much
easier for us to support the newest version.

Hallo Matthew,
thanks for your fast response. With "no beside the nonzero structure" I
meant, that I do not create a different non-zero structure while I'm
adding values to my matrices.
I also tried MAT_COPY_VALUES and the result was the same.
I do not get a error message but the resulting m

Hallo,
I have a strange behavior in my code concerning the function MatAXPY. I
create 3 different Matrices
ierr = MatCreateBAIJ(PETSC_COMM_WORLD, block_size, local_size,
local_size, system_size, system_size, 0, d_nnz, 0, o_nnz,&A);
ierr = MatSetOption(A,MAT_NEW_NONZERO_ALLOCATION_ERR

My admin did an install of petsc on ubuntu 14.0 using the package manager.
Things seem to be ok, expect I noticed the following when I compile using the
petsc rules:
mpicxx -o ex19.o -c -Wall -Wwrite-strings -Wno-strict-aliasing
-Wno-unknown-pragmas -O -fPIC-I/usr/lib/petscdir/3.4.2/incl

Eric,
I have now updated all the standard MPI matrix types AIJ, BAIJ, SBAIJ to
print the correct global indices in the error messages when a new nonzero
