Here is a strange error when using IntelMPI:  
After successful install and using IntelMPI runtime and complier, I have complied the fowllowing codes for mpi:

```auto
PROGRAM hello_world_mpi

include 'mpif.h'

 

integer process_Rank, size_Of_Cluster, ierror, tag

 

call MPI_INIT(ierror)

call MPI_COMM_SIZE(MPI_COMM_WORLD, size_Of_Cluster, ierror)

call MPI_COMM_RANK(MPI_COMM_WORLD, process_Rank, ierror)

 

print *, 'Hello World from process: ', process_Rank, 'of ', size_Of_Cluster

 

call MPI_FINALIZE(ierror)

END PROGRAM

```

I have complied it by using intel ifork complier by

```auto
 mpiifort hello.f90 -o hello

```

Then when I try to run such program as root user:

```auto
> mpirun -n 2 ./hello

 Hello World from process: 1 of 2
 Hello World from process: 0 of 2

```

**Everything goes right in root user.**  
When I try to run this in any other user, it get:

```auto
> mpirun -n 2 ./hello

[1733578910.431461221] RFRLServer7:rank89.hello: Unable to create send CQ of size 5080 on mlx5_bond_0: Cannot allocate memory

MPIDI_OFI_mpi_init_hook(1673): 
create_vni_context(2242).....: OFI endpoint open failed (ofi_init.c:2242:create_vni_context:Invalid argument)

```

It seems a wrong in this.  
The ifork information:  
ifort (IFORT) 2021.13.1 20240703  
The complier is 2024.2.  
The intel MPI is Intel(R) MPI Library for Linux\* OS, Version 2021.14 Build 20241121 (id: e7829d6)  
My cpu is Intel(R) Xeon(R) Platinum 8360H CPU @ 3.00GHz.  
The sysmtem is rocky linux 8.10.  
Is there anyone could help me with this problem?
