details like this are usually very dependent on how your sysadmins have configured your cluster.
would help if you posted your code, as well as logs showing why you think it is ignored.

Sorry for the late response @bjarthur , I had no access to lsf system till now.
The jobs are launched on the same node for example below:
julia> addprocs_lsf(4,bsub_flags=`-R "span[ptile=2]"`)
[ Info: `bsub -R 'span[ptile=2]' -cwd ... -J 'julia-649580[1-4]' .../julia --worker=HD6PDHgBP`
julia> pmap(i->gethostname(),1:nworkers()) |> unique
1-element Vector{String}:
"r310n11"
Without job arrays two nodes as expected:
bsub -Is -n 4 -R "span[ptile=2]" mpirun hostname
Job <512551> is submitted to default queue ...
<<Waiting for dispatch ...>>
<<Starting on r309n05>>
r309n07
r309n07
r309n05
r309n05
I appreciate the help!
