 Hi Fabrice,

 Sorry, there are not plans at the moment to make Ipopt threadsafe.  It
 might actually not be that difficult, as long as none of the smart
 pointers are shared between the individual threads.  But beside the smart
 pointers, we currently use global variables for the tagging of vector and
 matrix objects - this could be changed, probably with not too much
 problems, but I don't think I will get to this soon...

 If you would want to take a look at it, I'm talking about the
 "unique_tag_" member of the TaggedObject class in
 Ipopt/src/Common/IpTaggedObject.hpp . It might be possible to change the
 definition of a tag to include the basic pointer of the VectorSpace of
 MatrixSpace so that then the unique_tag_ could be moved into those
 spaces....

 Andreas
