how to install SuperLU_MT on windows

[Ning-Li-Ambition]

Hi, I try to install SuperLU_MT on windows with visual studio following your instructions on this webpage https://portal.nersc.gov/project/sparse/superlu/faq.html#windows. But it does not work and I got the following errors. Could you please help me to fix these errors? thanks

Unfortunately, none of the developers know about Windows. The tips in the FAQ page were provided by the users. But, from the error message you provided, it looks like just the timer issue: it is using the timer function on Linux. Can you replace it by the Windows timer you usually use? If you succeed, I would like to know how it is resolved. Sherry Li

I added NDEBUG;_LIB;_CRT_SECURE_NO_WARNINGS;__OPENMP;WIN32;UpCase; to property page->C/C++->Preprocessor->Preprocessor definitions. and build the library successfully. But when I linked the library SuperLU_MT.lib to my Fortran visual studio project, I got the linker error:
Severity Code Description Project File Line Suppression State
Error error LNK2019: unresolved external symbol PDGSSV referenced in function MAIN f77_main.obj

[xiaoyeli]

Can you take a look at README, the section discussing CDEFS. Some name mangling is needed between Fortran and C programs.

[Ning-Li-Ambition]

I read that section, and I also read the source file slu_mt_Cnames.h. That is why I added UpCase to Preprocessor definitions.
I think the problem is the library generated does not provide a linkage to those functions. and extern "C"
keyword might be necessary.

[xiaoyeli]

I suggest that you write a small program to test out the Fortran-C calling needs on your machine.

[Ning-Li-Ambition]

Hi, Sherry, this is my test result:

1. I built a static library in c++ with visual studio, this is the source code
   1.1 Cpp_lib.h
   #pragma once
   extern "C" double add(double* a, double* b, double* c);
   1.2 Cpp_lib.cpp
   #include "Cpp_lib.h"

     double add(double* a, double* b, double* c) {
     *c = *a + *b;
     return *c;
      }
   

2. my fortran code
   program main
   use, intrinsic :: ISO_C_Binding, only: C_DOUBLE
   implicit none
   double precision :: a, b, c

   interface
   subroutine add(a, b, c) bind(C,name="add")
   import
   real(C_DOUBLE) :: a, b, c
   end subroutine
   end interface

   a = 1.0D0
   b = 2.3D0
   call add(a, b, c)

   print*, 'c: ', c
   pause
   end program main

3. result
   I run the fortran code with visual studio, there is no problem.
   then I tried to do the same thing with SuperLU_MT, but in your source code, I could not find the definition of c_bridge_dgssv

[xiaoyeli]

Are you using C++ compiler? If so, can you try add c_bridge_pdgssv in side extern "C" { ...} in SRC/slu_mt_ddefs.h ?

[Ning-Li-Ambition]

yes, visual studio 2019 uses C++ compiler.
what should be the definition of c_bridge_pdgssv? same as pdgssv?

[xiaoyeli]

I just pushed a commit, adding c_bridge_pdgssv_ in SRC/slu_mt_ddefs.h.
You can try the master branch.

[jschueller]

it builds now with visual studio using cmake

I think there might be a problem with current version (4.0.0) for Windows users. I know main developers does not use Windows, but I hope there might be some developers or users that support the package for Windows. So I built 4.0.0 yesterday this way: created C++ project and added all .c and .h source files, then liked Intel MKL (I use Intel C++ compiler 2024), set preprocessor definitions USE_VENDOR_BLAS and _OPENMP and built a .lib. I cannot build superlu_mt version 3.1 this way though, because of "Error: call to undeclared function 'ccopy'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration] superlu_v31_intel_build path\SuperLU\SuperLU_MT_3.1\SRC\clacon.c(159,5): 1". I don't know how easy it can be fixed but I do not really need this version. But I can build as well some intermediate code I downloaded in spring 2023 and it is different from the current 4.0.0 version (I attach the archive). The problem is the code (I also attach the code and a small matrix in another archive) works fine on an intermediate version (relative residual output 1.317e-12, info=0, nnz(L+U)=1192547) and works wrong on 4.0.0 version (relative residual output 2.338e+09, info=0, nnz(L+U)=1189830). Please tell me what can be the reason of such behaviour and whether someone built and used 4.0.0 version on Windows with MSBuild (Visual Studio) successfully.

superlu_test.zip

[ChessMastery]

Seems like I fixed it. First I tried to set [int nprocs = 1] instead of [int nprocs = 4] and itworked correctly. Then I tried turn off OpenMP support MSBuild option while building 9.0.0 version and it worked.

[ChessMastery]

I realized I just turned off OpenMP support and OpenMP directives were ignored. When I build like this, SuperLU_mt with sequential BLAS works a little bit slower than sequential SuperLU. When I build with OpenMP support, I get huge residual with both 4.0.0 and older versions, but when I set OpenMP threads number as 1 I get normal residual. Could you please tell what steps did you do in order to build correctly working SuperLU_mt with OpenMP and Visual Studio?

[jschueller]

the infos on the website are outdated, as it can be built using cmake now that should set the right compilation options for you, here is an example using cmake + ninja:

git clone -b v4.0.1 --depth 1 https://github.com/xiaoyeli/superlu_mt.git
cmake -LAH -G "Ninja" -B build_slu -S superlu_mt -DPLAT="_OPENMP" -DBUILD_SHARED_LIBS=OFF -Denable_tests=OFF -Denable_examples=OFF
cmake --build build_slu

[ChessMastery]

These commands worked for me, thanks a lot!
P. S. I also added -DCMAKE_BUILD_TYPE=Release option in the 2nd command, or it can be specified in the root CMakeLists.txt file as set(CMAKE_BUILD_TYPE Release). Without this option, the solver works about 2 times slower on some matrices I tested (e. g. COLAMD permutation is calculated 2 times slower).
