[petsc-users] statistics on matrix passed to mumps

[Luc Berger-Vergiat]

Hi,
I have an integer memory allocation when I call mumps to solve my linear 
problems.
mumps report a memory error: INFOG(1)=-7 when it allocates IRN and JCN, 
these two arrays being of size NZ.
mumps documents also defines NZ as the numbers of entries being input.

I want to know what is the size value of NZ so that I can determine how 
to partition my system of equations correctly.
So far I call: MatGetInfo(Kmat, MAT_LOCAL, info, ierr) in order to get 
the statistics on my matrix.
I want to know if info(MAT_INFO_NZ_ALLOCATED) corresponds to the NZ of 
mumps?
If it is not the case how can I recover that mumps NZ value?
