Hello,
I'm having trouble with the MatView function drawing the matrix
structure(s) when I execute my code on multiple processors.
When I run on a single processor, the code runs fine, and the
graphics window displays cleanly.
Lets start with an example. I do this
cd $PETSC_DIR/src/snes/examples/tutorials
make ex19
Make sure it runs
./ex19 -snes_monitor
Make sure it runs in parallel (maybe you need
$PETSC_DIR/$PETSC_ARCH/bin/mpiexec)
mpiexec -n 2 ./ex19 -snes_monitor
Make sure it can draw
mpiexec -n 2 ./ex19 -snes_monitor -mat_view draw -draw_pause 1
This runs fine for me. Can you try it?
Thanks,
Matt
Hello Matt,
Yes, this example seems to run just fine. How should I proceed?

When I run with multiple processors, I get error messages (see below).
The matrices are constructed with DMCreateMatrix(da, &A_matrix).
I then set the values with
MatSetValuesStencil(A_matrix,1,&row,2,col_A,value_A,INSERT_VALUES).
Finally, I call MatAssemblyBegin(A_matrix,MAT_FINAL_ASSEMBLY) and
MatAssemblyEnd(A_matrix,MAT_FINAL_ASSEMBLY).
I also test that the matrices are assembled with
MatAssembled(A_matrix, &is_assembled_bool), and it appears they
are successfully assembled.
Any help/advice is greatly appreciated.
Thanks in advance!
