[Ipopt] Can PARDISO 4.0 work with ipopt in windows?

Thu Feb 18 15:13:46 EST 2010

York,

I use Visual Studio 2008 to build IPOPT 3.8.  In my case, I build IPOPT as a static library and link it with PARDISO.  If you are using Visual Studio, you must make sure that the file "IpPardisoSolverInterface.cpp" is included in your project file, or it will not be compiled even if you've changed it.  I've noticed that some IPOPT source files have not been included in the Visual Studio project file, and I've had to manually add some on occasion.

If you are building PARDISO as a DLL, you have to perform a few additional steps.

1.  When you build the IPOPT DLL, you will need to link it with the import library named "libpardiso400_INTEL_IA32.lib".  This is done so that when the IPOPT DLL is loaded by your executable, it can find the PARDISO functions it needs at runtime in "libpardiso400_INTEL_IA32.dll".  The process of building the IPOPT DLL should also produce a .lib file of the same name as the DLL.

2.  When you build your executable, you must link your code to the .lib file that was produced when building IPOPT.  This way, your executable can find the IPOPT functions it needs in the accompanying DLL at runtime.

3.  The file libiomp5md.dll is a runtime library (not to be confused with the import libraries mentioned above), and needs to be in the same directory as your executable.  This DLL is used to support the Intel MKL code that is used by PARDISO.  It may also be located somewhere else, provided that your system can find it, ie, it needs to be in a directory defined by the PATH environment variable.

4.  Do not rename "libpardiso400_INTEL_IA32.dll", or it will not be properly located at runtime.  If you link IPOPT with libpardiso400_INTEL_IA32.lib, it expects to use a runtime DLL of the same name.

5.  You probably do not need the PARDISO_Template.zip file - I didn't need it.

6.  At run time, your executable, the IPOPT DLL, and file libiomp5md.dll must all reside in the same directory or be located in a directory defined by the PATH environment variable.

Dear Teeter,

I have tried your step, but still crash when the solver start (do not print any msg from the process)

Here is what i have done.

1. First i download the( INTEL, 32-bit, icc/ifort 10.1 Windows) (with MKL BLAS) Version of PARDISO.
It has 4 files(libpardiso400_INTEL_IA32.dll,libpardiso400_INTEL_IA32.lib,libiomp5md.dll,PARDISO_Template.zip)
2. I named the "libpardiso400_INTEL_IA32.dll" to "libpardiso.dll". Put it next to my exe. (my exe can detect the licence is wrong, if i input a invalid licence file)
3. And do all the thing that you mentioned. and replace the old Ipopt38.dll with the new one.

Where is my problem?
Also What i need to do with the libpardiso400_INTEL_IA32.lib,libiomp5md.dll,PARDISO_Template.zip? (if i just want to use the PARDISO with ipopt)
Thank you so much for your help!

	York,

	PARDISO does indeed work with IPOPT.  I had an experience similar to
	yours, but this is how I fixed it:

	1.  At the top of the IPOPT source file IpPardisoSolverInterface.cpp,
	add the following preprocessor definition if it does not already exist:

	#ifndef HAVE_PARDISO_NEWINTERFACE
	#define HAVE_PARDISO_NEWINTERFACE 1
	#endif

	2.  In the same source file, remove the F77_FUNC() macro definition from
	ALL references to functions PARDISOINIT() and PARDISO().  For example,
	instead of the original function prototype:

	void F77_FUNC(pardisoinit,PARDISOINIT) (void* PT, const ipfint* MTYPE,
	                                                   const ipfint*
	SOLVER,
	                                                   ipfint* IPARM,
	                                                   double* DPARM,
	                                                   ipfint* ERROR );

	Use the following version instead:

	void PARDISOINIT(void* PT, const ipfint* MTYPE,
	                                                   const ipfint*
	SOLVER,
	                                                   ipfint* IPARM,
	                                                   double* DPARM,
	                                                   ipfint* ERROR );

	I commented out the original references and created the modified
	versions to be used instead.  Do the same for all function calls as
	well, and this should fix your problem after rebuilding IPOPT.

	One final point: If you haven't already done so, remember to define
	HAVE_PARDISO and HAVE_PARDISO_PARALLEL (if applicable) in the IPOPT
	source file IpoptConfig.h

	York,

	The PARDISO 4.0.0 DLL is working correctly with IPOPT. I am copying
	Chuck Teeter in this email since he is actually using IPOPT and PARDISO
	on Windows.
