Parallel Studio XE 2017 on MS Visual Studio CONFIGURATION

[Alexandre_M_1]

I am very confused when it comes to use the mpi library under the Visual Studio environment.

I have several folders with mpi stuff under IntelSWTools and have no clue if I even need an additional one besides the original installation.

I tried to include the path for each of these folders to the Project Properties (Fortran, Linker etc) but nothing seems to work.

Would anyone have a straight forward way to solve this?

I am trying Intel's example and the log is below.

Many thanks!

I suggest you ask this in https://software.intel.com/en-us/forums/intel-clusters-and-hpc-technology

[Kevin_D_Intel · Accepted solution]

With the example you provided try this:

• Create a new (empty) Fortran Console project.
• Add an x64 configuration and set that as the default configuration.
• Under source files, add the source file corresponding to the example you've shown.
• Under Properties set (for all Configurations) set:
•      Fortran > General > Additional Include Directories to $(I_MPI_ROOT)\intel64\include
•      Linker > General > Additional Library Directories: $(I_MPI_ROOT)\intel64\lib\release
•      Linker > Input > Additional Dependencies to impi.lib
• Build the solution/project

With a successful build:

• Open a pre-initialized Fortran Command prompt window (these are what you found in your earlier thread)
• Run the mpivars.bat  (Note: Adjust the path to the version of MPI you have installed)   For example:

                 C:\>  "C:\Program Files (x86)\IntelSWTools\mpi\5.1.3.246\intel64\bin\mpivars.bat"

• Change directory to the Debug or Release folder for your solution and run: mpiexec –np 4 Console.exe

Here are some getting started guides:
https://software.intel.com/en-us/get-started-with-mpi-for-windows
https://software.intel.com/en-us/node/610381

The latter one has the three keys VS settings needed that are mentioned above.

There is additional documentation available at: https://software.intel.com/en-us/intel-software-technical-documentation  (Use the left-side Products Filter to select Intel MPI Library)

From your build output, it looks like you may only need to replace <configuration> under Additional Library Directories with a selection of the libraries you want to use i.e. debug, release, debug_mt, release_mt as discussed on the page I noted earlier, https://software.intel.com/en-us/node/610381

[Alexandre_M_1]

Many thanks you both. I will give it a try tomorrow. I am about to reach that "uninstall everything and re-start from the beginning point"...

[Alexandre_M_1]

Why not give it a try?

When I told it to build, I got an error related to the impi.lib, below. I have loads of impi.lib under the root folder but unsure if I am telling the compiler its path...

[Alexandre_M_1]

A solution:

I copied one of these files into the project folder and the build was successful...   I will look at the other details later but I am sure this is not the best way forward... I put an .f90 in the end so I could upload it...

[Kevin_D_Intel]

The first line of the build output shows for LIBPATH that you added the include path for MPI into the linker's Additional Libraries setting and not the MPI library path. Compare your project settings to those that I posted earlier. This only requires the three settings that I noted. It doesn't require copying MPI files. Your is working as a by-product of the linker searching the current build directory.

[Alexandre_M_1]

Many thanks again.

Please note below:

/OUT:"x64\Debug\ex0.exe" /INCREMENTAL:NO /NOLOGO /LIBPATH:"C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2017.1.143\windows\mpi\intel64\include" /MANIFEST /MANIFESTFILE:"x64\Debug\ex0.exe.intermediate.manifest" /MANIFESTUAC:"level='asInvoker' uiAccess='false'" /DEBUG /PDB:"D:\_1 - shared\_Arquivos\Alexandre\_Tecnicos\Pós-Doutorado\Exercicios MPI\ex0\ex0\ex0\x64\Debug\ex0.pdb" /SUBSYSTEM:CONSOLE /IMPLIB:"D:\_1 - shared\_Arquivos\Alexandre\_Tecnicos\Pós-Doutorado\Exercicios MPI\ex0\ex0\ex0\x64\Debug\ex0.lib" impi.lib

> There is no impi.lib under that folder (Intel08.png) - strange? The folder intel64 under 2017.1.143 only has bin and etc - no include nor lib...

Also, I double checked that I included the entries as indicated - another strange thing?

• Under Properties set (for all Configurations) set:
•      Fortran > General > Additional Include Directories to $(I_MPI_ROOT)\intel64\include
•      Linker > General > Additional Library Directories: $(I_MPI_ROOT)\intel64\lib\release
•      Linker > Input > Additional Dependencies to impi.lib

Many thanks again!

[Kevin_D_Intel]

You are just overlooking the incorrect setting in the properties settings. The Intel09A.png shows where you have the wrong setting. The Linker > General > Additional Library Directories setting needs to be:  $(I_MPI_ROOT)\intel64\lib\release     (it is incorrectly set to the MPI include path)

[Alexandre_M_1]

I am sorry the delay but I would like to thank you for your help. All is working fine now! :-)
