Hello,
I have to test the ParMetis ordering for factorization and i would like
to known if it's possible to use a user ordering ?
If i understand the manual correctly, i have to use
MatOrderingRegisterDynamic and PCFactorSetMatOrdering but the sentence
Currently we support orderings only for
1) The PETSc LU and Cholesky solvers only run sequentially.
2) The parallel LU and Cholesky solvers PETSc interfaces to, SuperLU_dist,
MUMPS, Spooles, DSCPACK do NOT accept an external ordering provided for
them.
Hence we do not have any setup for doing parallel matrix
Hi,
i was wondering in MatSetValues, when i need to specify the number of columns,
whether that is the number of column entries per row?
So, if i want to insert two rows at five entries each, do i specify 5 or 10
for the number of columns?
So something like this:
m_ierr =
It is 5, also the length of GlobalColIndices is 5, not 10.
Each row you pass in has the values in the same columns.
