Make tests fail when building with Intel MKL libraries

[BenVanDerMeer]

I'm trying to build Ipopt using the Intel MKL libraries. I'm using Ubuntu 22.04 with Ipopt 3.14.17, and Intel MKL 2025.0 library. I configure Ipopt with:

 ../configure --with-lapack-lflags="-L${MKLROOT}/lib/intel64 -Wl,--no-as-needed -lmkl_intel_lp64 -lmkl_sequential -lmkl_core -lm"

This works without any issues. I then do:

make

Again, no issues. But then I do:

make test

And I get the following output:

There's more output with further tests that fail in a similar manner. No explicit errors but Ipopt just can't seem to solve any of the problems. Any idea why this is happening and how I can fix it?

[svigerske]

Increasing the print_level or enabling Pardiso output (pardisomkl_msglvl) may give more information.

The test still works with MKL 2024.2 for me. And the MKL 2025.0 release notes mention that some work has been done on pardiso.

[BenVanDerMeer]

Hi Stefan, thanks for the response. Downgrading to MKL 2024.2 has worked for me also, all tests passed successfully. Not sure what the issue with version 2025.0 is.

[svigerske]

I can reproduce with current MKL 2025.0.1.16. If I enable the log, and compare with MKL 2014.2, then there is a difference in the Pardiso call in PardisoMKLSolverInterface::Solve().

With MKL 2024.2 it says

Times:
======
Time spent in direct solver at solve step (solve)                : 0.000027 s
Time spent in additional calculations                            : 0.000005 s
Total time spent                                                 : 0.000032 s

With MKL 2025.0.1, I only get

Times:
======
Time spent in additional calculations                            : 0.000004 s
Total time spent                                                 : 0.000004 s

This is when pardiso is called with PHASE=33, so it should do some solving (https://www.intel.com/content/www/us/en/docs/onemkl/developer-reference-c/2025-0/pardiso.html#GUID-FB4D5442-2BE8-4687-A6F6-D2AAE34B8A87).

I can track it down to

Ipopt/src/Algorithm/LinearSolvers/IpPardisoMKLSolverInterface.cpp

Line 238 in d63fe2c

IPARM_[20] = 3;// bunch-kaufman pivoting

If I comment out this line, it seems to work again.

[svigerske]

Follow-up with Intel in https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Pardiso-bunch-kaufman-pivoting-option-3-different-in-MKL-2025-0/m-p/1648273

[svigerske]

Current stable/3.14 and next release will change to IPARM_[20]=1 if MKL 2025 or higher and pardisomkl_max_iterative_refinement_steps is > 0 (default is 1). That should work around the issue. I don't know whether there is an effect on performance.

I'll probably remove the workaround in a future version if there is a fixed MKL version available.
