[Coin-ipopt] MKL Pardiso

[Andreas Waechter]

Hi Javier,

As far as I know, the current release of the MKL does not have a version 
of Pardiso in there that includes the changes that the Pardiso developers 
Olaf Schenk and Michael Hagemann did to make it work correctly with Ipopt. 
(Olaf and Michael, if you are reading this, is that correct?).

You might be lucky that it sometimes works with the Pardiso version in the 
MKL, particularly if you are solving a convex problem (most changes were 
related to correctly handling the non-convex case).

By the way, in the Pardiso library currently available at the Pardiso 
website, a few minor changes are not yet included, but they are not 
essential.  However, if you obtain Pardiso from there, you probably should 
get the new releaes once it is out...  I will try to remember to make sure 
that we send a message to the mailing list when that happened.

Hope this answers your question,

Andreas
