.NET Projects

Please refer to Compiling and Porting Serial Applications for a detailed description of creating VS 2005 projects using C/C++ or Fortran.

General Directions:

  • Designate the multi-threaded run time libraries for the debug and release versions under the property pages for the project, if you are using one of the C/C++ compilers. The defaults are correct for Fortran.

MS Visual C/C++ and Intel C/C++:

  • Add paths to C:\Program Files\MPIPro\Include and C:\Program Files\MPIPro\Lib (these paths can be project specific or added as default paths that will be used for all of your projects)
  • Add MPIPro.lib as an additional dependency

Intel Fortran:

  • Add path to C:\Program Files\MPIPro\Lib (this path can be project specific or added as a default path that will be used for all of your projects)
  • Add MPIPro.lib as an additional dependency
  • Add mpipro_cdec.lib as an additional dependency
  • Include mpif.f90 as a source file in your project
  • Use lowercase names

Following is a detailed discussion of the additional steps needed to compile a parallel application in Microsoft Visual Studio 2005.

MPI Libraries

To make your application communicate using MPI/Pro, MPI/Pro must be installed on the machine where you are compiling the parallel executable (MPI/Pro is available on the winlogin nodes and in the Collaboratory). The MPIPro library must be added to the Linker as an additional dependency. To add MPIPro.lib go to project properties; make sure that All Configurations is selected in the Configuration: window, then go to Linker | Input | Additional Dependencies and add MPIPro.lib here.

If you are using Intel Fortran, there are a few more steps. MPIPro_cdec.lib must also be added to the Additonal Dependencies list with a space between it and MPIPro.lib. To avoid some annoying warning messages when compiling, add libc.lib to Ignore Specific Library. You must also specify that lower case names will be used. Go to Fortran | External Procedures | Name Case Interpretation and add Lower Case.

Note: the MPI libraries are an example of limitations on your compiler options. The MPI/Pro library does not support the combinations [mixed case names and stdcall] or [uppercase names and cdecl].

Multi-threaded Libraries

Another important consideration when you build parallel programs is to use the correct runtime libraries. The MPI/Pro libraries have been built using the multi-threaded libraries, so it is best that you do so also.

If your project is written in C/C++, you should designate the multi-threaded libraries for the debug and release versions separately, because there are both debug and plain versions of the multi-threaded libraries for C/C++.

VS 2005 uses the correct Multi-threaded libraries for Intel Fortran by default, so you don't need to change the settings when you are writing Fortran code.

Go to the project properties dialog box for a project or source file.

Microsoft and Intel C/C++:

  • Go to C/C++ | Code Generation | Runtime Library
  • choose the libraries corresponding to what is in the Configuration: window (Debug Configuration = Multi-threaded Debug (/MTd); Release Configuration = Multi-threaded(/MT).

Note: you should change the properties of an individual source file only if they need to be different from the ones that have been set for the project.

Default paths

If you are going to be writing many programs using MPI, consider customizing your VS 2005 environment so that the include files and libraries will be found automatically. Even on the winlogin nodes, VS 2005 can be personalized to suit your needs. But be aware that the login nodes are separate machines, so any customization to VS 2005 you do on one login node will not automatically be applied to the others.

Microsoft C/C++:

  • Go to Tools | Options | Projects and Solutions | VC++ Directories
  • add C:\Program Files\MPIPro\Include to the Include files section
  • add C:\Program Files\MPIPro\Lib to the Library files section

Intel C:

  • Go to Tools | Options | Intel(R) C++ | Directories
  • add C:\Program Files\MPIPro\Include to the Includes: section. Each entry is separated by a semi-colon.
  • add C:\Program Files\MPIPro\Lib to the Libraries section. Each entry is separated by a semi-colon.

Intel Fortran:

  • Go to Tools | Options | Intel(R) Fortran | General
  • add C:\Program Files\MPIPro\Lib to the Libraries: section. Each entry is separated by a semi-colon.

Note: These paths can either be typed in or found by browsing.

Project Specific Paths

If you don't set up default paths, each project will need to be customized by putting in the include and  library paths on its project properties. This would make sense for a project that needs specific libraries that none of your other projects need. Go to the project's properties page and make sure that All Configurations shows in the Configuration: window,

All:

  • add C:\Program Files\MPIPro\Lib to Linker | General | Additional Library Directories

C/C++:

  • add C:\Program Files\MPIPro\Include to C/C++ | General | Additional Include Directories

Additional Fortran Steps

Include paths are not needed for Fortran projects because no include files are needed by MPI/Pro. Instead, a module definition file MPIf.f90 is needed. This file must be added as an additional source file and will be compiled with your other source files. It is located in C:\Program Files\MPIPro\Include.
