[Ipopt] Ipopt release 3.11.8

[Tony Kelman]

HAVE_MPI_INITIALIZED should get checked during Ipopt’s configure (check config.log in the Ipopt subfolder), then the value gets populated into Ipopt/src/Common/config.h. The MPI_Init might also get skipped if MUMPS_MPI_H is defined somewhere?

Thanks Stefan. I tried upgrading the Homebrew formula to 3.11.8 but I'm still getting the test failures due to MPI_Init():

./run_unitTests

==> Warning: Treating 1 binary and 1 integer variables as continous.

*** The MPI_Comm_rank() function was called before MPI_INIT was invoked.
*** This is disallowed by the MPI standard.
*** Your MPI job will now abort.
[Aragorn:91158] Local abort before MPI_INIT completed successfully; not able to aggregate error messages, and not able to guarantee that all other processes were killed!

I looked through the updated source code but it's not clear to me who's supposed to set HAVE_MPI_INITIALIZED?

Thanks

Dominique

  Hi,

  I just created a new Ipopt maintenance release.
  This release includes an important fix for a bug that has been introduced (by me) with Ipopt 3.11.0 and could be responsible for difficult to debug convergence problems. If you were using Ipopt 3.11, it is suggested to update.

  Here is a list of changes (r1234 stands for a related svn changeset, #123 for a ticket number in the trac bugtracking system):

  - fixed a bug, introduced with Ipopt 3.11.0, where the tag in the
    Ipopt's caching mechanism was not unique over time, which lead to
    failures of Ipopt that were difficult to debug or recognize
    (e.g., Ipopt may have stopped with an restoration failure for
    instances that solved fine with Ipopt 3.10) [r2472, r2473]
    I'm very thankful to Gabriel Hackebeil and Kurt Majewski for their
    debugging effort on this issue.
  - building Mumps with pthreads is now disabled by default [#229]
  - fixed setting of LD on Windows (now set to link only iff using
    MS/Intel compilers) [#230]
  - fixed download link for Gnumex [r2471]
  - for some messages about too-few-degrees-of-freedom and restoration
    failure, the message level changed from error to strong-warning
    [r2460, r2469]
  - revised calls to MPI_Init and MPI_Finalize in Mumps interface [r2467]
    (MPI_Init is now called only if function MPI_Initialized is available
    and MPI has not been initialized already; MPI_Finalize is only called
    if Ipopt also called MPI_Init; ...)

  The source tarballs should be available tomorrow.

  Enjoy,
  Stefan
