[sundials-users] SuperLUMT and Sundials

[David Halpern]

Hi,

I've been trying to build sundials with superlumt, and things fail each time. I've tried gnu and intel compilers, with the same outcome.  If using ccmake, I get errors like: ERROR: Could not find SuperLU_MT.  Please check the variables:

          SUPERLUMT_INCLUDE_DIR and SUPERLUMT_LIBRARY_DIR

I've typed the appropriate information but it still fails. I have also used cmake, using the command

cmake .. \

  -DCMAKE_INSTALL_PREFIX=/usr/local/sundials750-ifx \

  -DCMAKE_C_COMPILER=icx \

  -DCMAKE_Fortran_COMPILER=ifx \

  -DCMAKE_BUILD_TYPE=Release \

  -DBUILD_FORTRAN_MODULE_INTERFACE=ON \

  -DENABLE_OPENMP=ON \

  -DENABLE_LAPACK=ON \

  -DSUNDIALS_INDEX_SIZE=64 \

  -DENABLE_SUPERLUMT=ON \

  -DSUPERLUMT_INCLUDE_DIR=/usr/include/SuperLUMT \

  -DSUPERLUMT_LIBRARY=/usr/lib64/libsuperlumt_d.so \

  -DSUPERLUMT_THREAD_TYPE=Pthread \

  -DSUPERLUMT_WORKS=TRUE \

  -DBUILD_SUNLINSOL_SUPERLUMT=ON \

  -DEXAMPLES_ENABLE_C=OFF \

  -DEXAMPLES_ENABLE_CXX=OFF \

  -DEXAMPLES_ENABLE_F2003=OFF

This builds sundials libraries but there is nothing related to superlumt installed.  I can build with KLU, but I would rather use superlumt if possible.  

Also, I've had to switch off building fortran examples because they do not compile. This has been happened over the last few versions of Sundials, but this is not as critical.

Any suggestions would be appreciated.

Best regards,

Hi David,

 

What version of SuperLU MT are you using? It would be helpful if you supplied the CMakeCache.txt, CMakeOutput.log, and CMakeError.log files.

Hi Cody:

The SuperLU_MT Fortran module interface is not built in SUNDIALS 7.5.0, even when properly configured with BUILD_FORTRAN_MODULE_INTERFACE=ON and ENABLE_SUPERLUMT=ON. The C library builds successfully, but the Fortran bindings (fsunlinsol_superlumt_mod.mod) are missing.

Environment

SUNDIALS Version: 7.5.0

Compilers:

Intel ifx (Fortran) 2024.x

Intel icx (C) 2024.x

Also tested with gfortran 11.x (same result)

OS:  Fedora 43

SuperLU_MT: From SuperLUMT-devel package version 4.0.3.

Headers: /usr/include/SuperLUMT/

Libraries: /usr/lib64/libsuperlumt_d.so

Cmake command used: cmake .. \

  -DCMAKE_INSTALL_PREFIX=/usr/local/sundials750-ifx \

  -DCMAKE_C_COMPILER=icx \

  -DCMAKE_Fortran_COMPILER=ifx \

  -DCMAKE_BUILD_TYPE=Release \

  -DBUILD_FORTRAN_MODULE_INTERFACE=ON \

  -DENABLE_OPENMP=ON \

  -DENABLE_LAPACK=ON \

  -DSUNDIALS_INDEX_SIZE=64 \

  -DENABLE_SUPERLUMT=ON \

  -DSUPERLUMT_INCLUDE_DIR=/usr/include/SuperLUMT \

  -DSUPERLUMT_LIBRARY=/usr/lib64/libsuperlumt_d.so \

  -DSUPERLUMT_THREAD_TYPE=Pthread \

  -DSUPERLUMT_WORKS=TRUE \

  -DEXAMPLES_ENABLE_C=OFF \

  -DEXAMPLES_ENABLE_CXX=OFF \

  -DEXAMPLES_ENABLE_F2003=OFF

Note that I also tried with gnu compilers.

Make and make install work but there is no fortran superlumt stuff in the installation directories. So when one tries to compile with superlumt, compile/errors appear because the compiler cannot find the modules since they were not built. I'm attaching the CMakeCache.txt file.

By the way, I had to disable the building of the examples, since the fortran ones do not compile.

Happy Thanksgiving!

Best regards,

David

Hi David,

The SuperLU_MT module does not have a Fortran interface. See https://sundials.readthedocs.io/en/latest/sundials/Fortran_link.html#id2 for the currently supported modules.

Cody
