Update the binaries (dll) to a thread-safe version

Reported by: andreas Owned by: ipopt-team
Priority: normal Component: Ipopt
Version: 3.12 Severity: normal
Keywords: thread-safety Cc:



I am using IPOPT 3.11.0 downloaded from (Ipopt-3.11.0-Win32-Win64-dll.7z) and it works great.

But, I am currently in need of a thread-safe version of IPOPT and from what I understand the newer versions of IPOPT are thread-safe (

Are there any plans to update the pre-compiled libaries? Or is there any way to find updated dlls?

Thanks in advance!

Even though Ipopt itself should be thread-safe now, also the linear solver used by Ipopt needs to be thread-safe. However, the only open-source linear solver that is interfaced by Ipopt is MUMPS 4, which isn't thread-safe.
