Usage example: Allocate SLURM resources, e.g. via

salloc --ntasks=4 --cpus-per-task=8 --mem-per-cpu=8GB --time=1:00:00

Then start Julia within the shell started by salloc:

julia

Then, in the Julia session, run

using LegendDataManagement
legend_addprocs()

Query workers:

using TypedTables
Table(LegendDataManagement.distributed_resources())

legend_addprocs() should also work in a Julia process started via sbatch.

Note: The SLURM options --cpus-per-task and --mem-per-cpu are currently required for legend_addprocs() to work.
