Progressive Lab for Windows

In the previous labs, you have been working with a serial application, compiling and running it in batch. In this section, you will start transforming this into a parallel application by setting up Visual Studio to be able to compile with MPIPro.

Prerequisites:

1. Read Compiling Parallel Applications
2. H:\users\your_userid\lab\karp\ with a working solution file (karp.sln, created in the Compile lab segment, with updated code from the Add MPI lab segment). If this is not the case, rename the folder karpFparSolution or karpCparSolution to H:\users\your_userid\lab\karp\. Refer to the Logon and Copy Files lab for instructions for copying files.

Instructions using VS 2005:

1. Open the karp.sln solution file, which was created earlier. Open the file by navigating to H:\users\your_userid\lab\karp\, then double-click on the karp.sln file. Or open Visual Studio and then click on File | Recent Projects.
   
2. Assuming you want to add the MPIPro include and library paths and files to this project only, open the properties page for your parallel project. Make sure All Configurations is chosen in the Configuration box.
   C/C++:
   • To add the include path for MPIPro go to
     C\C++ | General | Additional Include Directories and type C:\Program Files\MPIPro\include
   • To add the library path for MPIPro go to
     Linker | General | Additional Libraries Directories and type C:\Program Files\MPIPro\lib
   • To add mpipro.lib as an additional dependency go to
     Linker | Input | Additional Dependencies and type mpipro.lib.
   • Change All Configurations to Debug
     Go to C/C++ | Code Generation | Runtime Library and select Multi-threaded Debug (/Mtd)
   • Change All Configurations to Release
     Go to C/C++ | Code Generation | Runtime Library and select Multi-threaded(/MT)
   Intel Fortran:
   • No include path for MPIPro is needed
   • To add the library path for MPIPro go to Linker | General | Additional Libraries Directories and type C:\Program Files\MPIPro\lib
   • To add mpipro.lib and mpipro_cdec.lib as additional dependencies go to Linker | Input | Additional Dependencies and type in mpipro.lib and mpipro_cdec.lib. A space is needed between the two library file names
   • To avoid some annoying warning messages, go to Linker | Input | Ignore Specific Library and type libc.lib
   • Go to Fortran | External Procedures | Name Case Interpretation and select Lower Case
   • Change All Configurations to Debug
     Go to Fortran | Libraries | Runtime Library and select Debug Multithreaded
   • Change All Configurations to Release
     Go to Fortran | Libraries | Runtime Library and select Multithreaded
3. Compile it on one of the login nodes. There are multiple ways to build an executable:
   • from the main menu choose Build | Build Project Name
   • add the Build Toolbar from View | Toolbars | Build and click on the Build icon
   • right-click on the name of the project in the Solution Explorer panel and choose the Build Solution option
   
   All the above actions will create a debug version of the same code by default. If you want the release version, you need to toggle the Debug/Release pane.
   

Instructions Using the Command Line:

1. Edit the code with your favorite editor
2. Compile the code
   Intel C/C++ 9.1:
   • setup_intelc32
   • setup_mpi
   • icl karp.c mpipro.lib
   Intel Fortran 9.1:
   • setup_intelf32
   • setup_mpi
   • ifort /Qlowercase karp.f mpipro.lib mpipro_cdec.lib

Results:

When you are done with this section, you should have a parallel executable ready to run.
