ClusterManagers.jl hangs on pbs

[ElOceanografo]

I ran into this issue last year, as have a few other people (see here and here). 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:

Help setting up Julia on a cluster

I recently went through the same learning process on my university’s cluster, and your second question was the hardest part for me. 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…
