So an alternative to ClusterManagers approach which does not rely on array jobs is as follows:

```julia
### Initializing cluster
isfile("machinefile") && rm("machinefile")

open(pipeline(`qsub -l nodes=2:ppn=2`), "w", STDOUT) do io
    println(io,"cat \$PBS_NODEFILE > machinefile; while [-f machinefile]; do sleep 1; done")
end

print("Queing")
while !isfile("machinefile")
    sleep(1)
    print(".")
end
println("")

cores = [(i, 1) for i in readlines("machinefile")]
clusterworkers = addprocs(cores; topology=:master_slave, dir="~",exename="julia")

### Doing some calculation

pmap(x->run(`hostname`),1:10)

### Killing the job and workers
rmprocs(clusterworkers)
rm("machinefile")

```
