Hi OpenMPI-community, This is a cross post from the following spack issue : https://github.com/spack/spack/issues/20756
In brief, when I install openmpi@4.1.0 with ucx and xpmem fabrics, the behaviour of the compiler wrappers (mpicc) seems to depend upon the method by which it is loaded into the user environment. When loaded by `spack load`, the compiler wrappers successfully compiler a test program. However, if the same compiler wrappers are loaded via `module load` or as part of a spack environment, they fail. What could possibly cause this inconsistency ? The build logs and the output of opmi_info are available here ( https://we.tl/t-CaiOt7OefS) should it be of any help. Thank You, Sajid Ali (he/him) | PhD Candidate Applied Physics Northwestern University s-sajid-ali.github.io
