Ok thank you I'll take a look at it,<br><br>I wanted to use SuperLU_dist as there is less mistakes during runs, and the last version seems faster.<br><br>Nicolas<br><br><br><div class="gmail_quote">On Mon, Mar 4, 2013 at 10:24 PM, Max Rudolph <span dir="ltr"><<a href="mailto:rudolph@berkeley.edu" target="_blank">rudolph@berkeley.edu</a>></span> wrote:<br>

MUMPS, but you could easily test this for yourself. I have not used it<br>
with GALE, only with my own codes. I do not think that the<br>
-mat_superlu_icntl parameter that you've set will do anything - that<br>
syntax is specific to the Petsc MUMPS interface. If you run with<br>
--log_summary, Petsc should provide you with a list of the options<br>
that you provided that had no effect when the program exits.<br>
