Hi Petsc Experts,
Trying to do something like appending some rows (~100 rows) to an already
created matrix, but could not find any document about it.
Could anyone provide some information about it?

f it is more efficient to reuse the matrix entries than recompute them you
can create a larger matrix and then loop over the old matrix calling
MatGetRow() and then call MatSetValues() to copy that row into the new matrix.

Hi,
I have a problem that need to interchange between two different DMDAs. They
have the exactly same size, however they are distributed/partitioned
differently across multiple processes. For instance, one DMDA is created with
DMDACreated1d, the other is created with DMDACreated3d. How can I in

Hi,
I was using MatMultTranpose and MatMult to solver a linear system.
However we found out, MatMultTranpose create an extra memory copy of matrix for
its operation. This extra memory copy is not stated everywhere in petsc manual.
This basically double my memory requirement to solve my system.
Hi,
I am running into a problem, different node/process take different time to run
petscinitialize. The difference could be 5~10mins.
I put some check before petscinitialize, and after petscinitialize.
MPI_Init(argc, args);
int rank;
MPI_Comm_rank(MPI_COMM_WORLD, &rank );
std:
Thanks. Let me fix that. Try it again.

Also you are mixing using the Intel MPI and OpenMPI, I am not sure this will
work.
