Thanks for your reply! And sorry for my late answer. I want to parallel a
particle-method code and solve Ax=b in each timestep. In this code, each
partition forms a CSR matrix and assembles the final coefficient matrix by
MatCreateMPIAIJWithArrays. But, the domain decomposition makes that the
When and where do you want to change the row order?
For PETSc and external factorization based solvers this is handled
automatically, no need to do anything.
The ordering of matrix rows corresponds to the ordering of the vectors;
almost always one partitions and orders the vectors bas
Hello,
I want to change the row order of a sparse matrix. Are there any build-in
functions and suggestions?
Thank you very much!
