Hi Yiheng,

Thanks for reaching out to us!

Could you please provide the command line you were using and also the logs after setting I_MPI_DEBUG=10.

SET I_MPI_DEBUG=10

If your error is code specific, then please provide us a sample to reproduce at our end.

If your error is specific to launching MPI, then try running the below command:

$ mpiexec.exe hostname

Warm Regards

My code is  a very simple code for test：

#include "mpi.h"
#include <iostream>

int main(int argc, char* argv[])
{
int rank;
int size;
MPI_Init(0, 0);
MPI_Comm_rank(MPI_COMM_WORLD, &rank);
MPI_Comm_size(MPI_COMM_WORLD, &size);
std::cout << "Hello world from process " << rank << " of " << size << std::endl;

MPI_Finalize();

return 0;
}

Hi Yiheng,

Sorry for the delay in response.

Please refer to this article (Configuring a Visual Studio* Project (intel.com)) where they have mentioned the required steps to set up and run MPI in Visual Studio.

After setting up if you want to add new environment variables like I_MPI_DEBUG add -genv I_MPI_DEBUG=10 as command arguments in Configuration Properties > Debugging.

example : -genv I_MPI_DEBUG=10 -n <processes-number> "$(TargetPath)"

Let us know if you face any issues.

Regards
