> 1. Is there a way to use this method in an interactive session (IJulia notebook)? It seems to require a command line execution.

Yes, this is something you have to do from the command line. Maybe you could try [this workaround](https://discourse.julialang.org/t/clustermanagers-package-not-connecting-for-pbs-batch-system/8879/8), from one of the threads linked above?

> 1. Is it possible to hack the existing ClusterManagers.jl code to accommodate this approach?

I don’t think so, at least not trivially…when you call `addprocs_pbs` ClusterManagers [generates a qsub script](https://github.com/JuliaParallel/ClusterManagers.jl/blob/63770d62e3b19572101b94f18e3b2c4297aeebdc/src/qsub.jl#L71) and submits it, then finds the addresses of the processors that were started and makes them available to Julia. With the `--machinefile` approach, you request the processors first, then tell Julia where to find them when it launches.

Though if @johnh is correct, it may just be a matter of sorting out some command-line flags for different flavors of PBS…
