one API mpi_abi.dll missing

CFL — Mon, 24 Nov 2025 11:05:12 GMT

Hi, I have been trying to run a simple Fortran program on Windows 11, and which uses mpi. It compiles without apparent error but when executed reports that the mpi_abi.dll is missing.

I checked the installation folders Intel/oneAPI/mpi/latest/bin and other folders but there is no file called mpi_abi.dll. Two other dll files are present: impi.dll and libmpi_ilp64.dll.

Have I missed something? I have re-installed the oneAPI code a couple of times but get the same issue. Is the mpi_abi.dll file created when the source code is compiled?

My compile instruction is:

ifx -threads /Qcoarray-num-images=8 /Qcoarray=shared Example_Code.f90

I also tried mpiifx -threads /Qcoarray-num-images=8 /Qcoarray=shared Example_Code.f90,

and got the same result.

Many thanks for any help.

Hi CFL,

I'm having the same problem. I've repaired the oneAPI HPC Toolkit but still have the same error as you. Did you manage to solve this issue?

Thanks

Shaun
