Hi,
OpenMPI-5.0.5 or 5.0.6 versions fail with following error during
"make" stage of the build procedure:

make[2]: *** [Makefile:1603: mtl_ofi.lo] Error 1
OpenMPI-5.0.7 surpasses this error, but it is not able build cuda [GPU
DIRECT] & ofi support:
Gromacs applications complains that it is not able to detect Cuda Aware MPI:
GPU-aware MPI was not detected, will not use direct GPU communication.
Check the GROMACS install guide for recommendations for GPU-aware support.
If you are certain about GPU-aware support in your MPI library, you can
force its use by setting the GMX_FORCE_GPU_AWARE_MPI environment variable.
OpenMPI is configured like this:
'--disable-opencl' '--with-slurm' '--without-lsf'
'--without-opencl'
'--with-cuda=/opt/nvidia/hpc_sdk/Linux_x86_64/25.1/cuda/12.6'
'--without-rocm'
'--with-knem=/opt/knem-1.1.4.90mlnx3'
'--with-xpmem=/sw/openmpi/5.0.7/g133cu126_ubu2404/xpmem/2.7.3/'
'--with-xpmem-libdir=/sw/openmpi/5.0.7/g133cu126_ubu2404/xpmem/2.7.3//lib'
'--with-ofi=/sw/openmpi/5.0.7/g133cu126_ubu2404/ofi/2.0.0/c126g25xu118'

'--enable-mca-no-build=btl-usnic'
Can somebody help me to build a successful cuda aware openmpi here?
Thanks
