[petsc-users] Memory usage during matrix factorization

[De Groof, Vincent Frans Maria]

Thanks. I made a new function based on the PetscGetCurrentUsage which does what I want. It seems like I am being lucky as the numbers returned by the OS seem to be reasonable.


thanks again,
Vincent

HPC vendors have a habit of implementing these functions to return
nonsense.  Sometimes they provide non-standard functions to return
useful information.
