MPI_Init failure on Windows 10

[BLH]

I'm using MPI 2021.10 on Windows 10 Pro and trying to get the benchmark examples running on a single process, in particular the one in benchmarks\imb\WINDOWS\IMB-MPI1_VS_2017.  I am using VS2019 though but the project upgraded fine.

I'm getting a failure in MPI_Init:

C:\PF(x86)\Intel\oAPI\m\2021.10.0\benchmarks\i\W\I-M1_V_2017\x64\Debug> IMB-MPI1.exe

The call stack is this:

impi.dll!PMPI_Init_thread() Unknown
IMB-MPI1.exe!main(int argc, char * * argv) Line 296 C++

IMB-MPI1.exe!mainCRTStartup(void * __formal) Line 17 C++
kernel32.dll!BaseThreadInitThunk() Unknown
ntdll.dll!RtlUserThreadStart() Unknown

Any ideas?  I'm stuck.

I think we found the problem.  We were testing in a Windows command prompt, not the Intel oneAPI Command Prompt which sets up a different environment.

We finally got this to work in a Windows command prompt by copying a few more files from the MPI installation to the same location as our executable.

Specifically:

libfabric/bin/libfabric.dll

bin/release/impi.dll

libfabric/bin/utils/fi_info.exe

libfabric/bin/utils/fi_pingpong.exe

I'm assuming we can redistribute these.

Hi,

Thanks for posting in the Intel forums.

We have tried to replicate the issue at our end but we are able to run the IMB benchmark successfully at our end. Please refer to the below attachment for the output details.

OS: Windows 11

To investigate more regarding the issue could you please provide us with the below details?

1. cpuinfo

2. visual studio version

Thanks & Regards

Hi Shivani,

I wrote on 10/24/2023 that we solved our technical issue.

Can you confirm which files in the installation that we are allowed to redistribute with our commercial product?

Sorry for the inconvenience. I missed your second post, so responded back we are unable to replicate the issue.

>>>"Can you confirm which files in the installation that we are allowed to redistribute with our commercial product?"

Regarding this, we will get back to you.

Thanks & Regards
