I ran into this issue last year, as have a few other people (see [here](https://discourse.julialang.org/t/help-setting-up-julia-on-a-cluster/5519) and [here](https://discourse.julialang.org/t/clustermanagers-package-not-connecting-for-pbs-batch-system/8879/5)). It seems like the interactive `addprocs_pbs()` approach doesn’t work on all clusters. The details of why not I can’t tell you, but an alternative approach is to use Julia’s `--machinefile` option on startup to tell it which processors PBS has allocated you…basically the cluster version of running `julia -p 2 myscript.jl` on a laptop:

I found the easiest way was to submit to one of the queues using a PBS submit script that tells Julia where to find all the processors via the PBS nodefile. Here’s a minimum working example PBS script: #!/bin/bash #PBS -l nodes=4:ppn=12,walltime=00:05:00 #PBS -N test\_julia #PBS -q debug echo PBS: node file is $PBS\_NODEFILE julia --machinefile=$PBS\_NODEFILE /path…
