Actually, it's not ten years out of date. It's ten years' diverged
from the original code, but if you look at the changelog for the
releases Intel has put a significant amount of work into Pardiso to
improve performance and robustness. We use MKL Pardiso in optimal
control problems with over 20 million variables and it's by far the
fastest linear solver at that scale in IPOPT, especially on Intel
hardware. <br></div><div bgcolor="#FFFFFF" text="#000000">

<br>
Intel has recently (September) made their MKL for the three
main<br>
operating systems available for free. You don't get any
support or old<br>
versions, but it is a good way to have access to MKL's Pardiso
for use<br>
in IPOPT. I haven't seen this on the list so I thought I'd
bring it up.<br>
