Mpi code not running

Lamine06F — Fri, 22 Sep 2023 19:42:32 GMT

I have a simple code and here isit :

program MPI_program

use MPI

implicit none

! Data declarations for MPI

INTEGER :: ierr ! error signal variable. Standard value = 0

INTEGER :: rank ! process ID / Number

INTEGER :: nprocs ! number of processors

! Initialize MPI

! Initialize subroutine

CALL MPI_INIT(ierr)

! Setup Communicator sizé

CALL MPI_COMM_SIZE(MPI_COMM_WORLD, nprocs, ierr)

! Setup ranks/IDs for each process

CALL MPI_COMM_RANK(MPI_COMM_WORLD, rank, ierr)

! Type the main code

print *, 'Hello World ! I am process', rank, ' of ', nprocs, 'Process(es)'

! Finalize MPI

! Finalize subroutine

CALL MPI_FINALIZE(ierr)

end program MPI_program

and Ihave followed all the instruction given here https://www.intel.com/content/www/us/en/docs/mpi-library/developer-guide-windows/2021-9/configuring-a-microsoft-visual-studio-project.html to config it. At the end, when I hit ctrl+F5 to build it, I have this error :
Erreur fatal error LNK1181: impossible d'ouvrir le fichier en entr‚e 'impi.lib' LINK.

Please any clue about what is wrong

Thanks

Hi,

Thanks for posting in Intel communities.

I have attempted to recreate the problem using the code you provided, and I am pleased to inform you that it compiles without any issues.

To assist you further, I have attached the following for your reference:

Screenshots of the Configuration Settings
Project Files
Compilation Screenshot

It is worth noting that during my investigation, I discovered that the issue can indeed be recreated if the following setting is not correctly configured or left empty:

Properties -> Linker -> General -> Additional Library Directories

Please configure it with the path "$(I_MPI_ONEAPI_ROOT)\lib\$(ConfigurationName);$(I_MPI_ONEAPI_ROOT)\lib".

I have included a screenshot highlighting the problem when this setting is not correctly configured.

If the issue persists on your end despite using the provided configuration settings, please provide the following details:

Your Project Files
Screenshots of Configuration Settings
Output of "lscpu" Command
Operating System Version and Details
One API Toolkit Version
Visual Studio Version

With the above mentioned details, we can perform a detailed analysis of the issue.

Thanks and Regards,

Veena
