#58: MA57 & MeTiS for IPOPT
------------------------------+---------------------------------------------
Reporter: pmota | Owner: ipopt-team
Type: defect | Status: new
Priority: normal | Component: Ipopt
Version: 3.3 (C++ Version) | Severity: normal
Keywords: MA57 MeTiS |

Dear Coleagues:
I am trying to build an ipopt executable (with cygwin) in which MA27 is
replaced by MA57. The latest version of MA57 recommends linking it with
the MeTiS package (http://www-
users.cs.umn.edu/˜karypis/metis/metis/download.html). The experience of
the developers of MA57 is that the choice of ordering can be quite crucial
to performance so their default invokes logic that chooses automatically
between the MeTiS ordering and a version of approximate minimum degree. In
general, the MeTiS ordering gives the best results for large matrices and
so they recommend that the user should ensure that this library is
available. Now, MA57 is a fortran code and MeTiS is a C code. Has anyone
actually compiled MA57 with MeTiS for IPOPT?
Regards,
Paulo Mota
