I am using this parameter "shmem_mmap_relocate_backing_file" and noticed that the relocation variable is identified as "shmem_mmap_opal_shmem_mmap_backing_file_base_dir" in its documentation, but then the next parameter that appears from ompi_info is spelled differently, namely "shmem_mmap_backing_file_base_dir".
Is the first name just a typo? > MCA shmem: parameter "shmem_mmap_relocate_backing_file" > (current value: > <0>, data source: default value) > Whether to change the default placement of > backing files or not > (Negative = try to relocate backing files to > an area rooted at > the path specified by > > shmem_mmap_opal_shmem_mmap_backing_file_base_dir, but continue > with the default path if the relocation > fails, 0 = do not > relocate, Positive = same as the negative > option, but will fail > if the relocation fails. > MCA shmem: parameter "shmem_mmap_backing_file_base_dir" > (current value: > </dev/shm>, data source: default value) > Specifies where backing files will be created when > shmem_mmap_relocate_backing_file is in use.
