+Running Julia interactive jobs
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+
+Interactive jobs allow a user to interact with applications on compute nodes. With an interactive job, you request time and resources to work on a compute node directly, which is different to a batch job where you submit your job to a queue for later execution.
+
+Using ``salloc``
+
+Using ``salloc``, you allocate resources and spawn a shell used to execute parallel tasks
+
+.. code-block:: console
+
+   $ salloc -A project_465001310 -N 1 -t 1:00:00 -p standard-g
+
+Once the allocation is made, this command will start a shell on the login node. You can start parallel execution on the allocated nodes with srun.
+
+.. code-block:: console
+
+   $ srun --ntasks-per-core=1 julia script.jl
+
+
+
+Using ``srun``
+
+For simple interactive session, you can use srun with no prior allocation. In this scenario, srun will first create a resource allocation in which to run the job. For example, to allocate 1 node for 10 minutes and spawn a shell
+
+.. code-block:: console
+
+   $ module use /appl/local/csc/modulefiles
+   $ module load julia
+
+   $ srun --account=project_465001310 --partition=standard-g --nodes=1 --cpus-per-task=1 --ntasks-per-node=1 --time=0:10:00 --pty julia script.jl
