Running Julia Trainings

Submitting a Julia Training Job

  1. Constructing your command

    At the very least, your command should have two steps in it:

  1. Activating your environment.

    As mentioned before, you must have already configured a Conda environment with a given name. If for example, your Conda environment is named julia_env, the first part of your command should be conda activate julia_env

  2. Calling your script.

    As explained in the setup guide, your Julia script should run the training process based on a CLI call. If for example, your Julia file is named main.jl, the first part of your command should be julia --project main.jl

+ These parts, and any part you choose to add in between/anywhere else, should all be joined with a double ampersand (i.e. &&).

Example 1. Explicit resources
$ ssh bhn20 (1)
$ runai-bgu submit julia \ (2)
  -n conv-2-64 \ (3)
  -c 2 \ (4)
  -m 4Gi \ (5)
  -g 1 \ (6)
  --conda julia_env \ (7)
  -- "julia --project main.jl" (8)
1 Configure SSH connection to bhn20
2 Specifies it is a Julia.
3 Specifies the name of the job.
4 Allocates 2 CPU cores.
5 Allocates 4GiB of memory*.
6 Specifies the GPU allocation(Whole or fractions). If you do not need GPU, do not use this flag.
7 Tells The Job to use the julia_env Conda environment.
8 The command to run, here julia --project.
The space ( ) between the two dashes (--) and the command is intentional. As are the quotes (") surrounding the command.
When running the command you can change directory to the location of your Julia file (cd ~/path/to/file && julia --project main.jl), or give the full path (julia --project ~/path/to/file/main.jl ).

You can also use a predefined resource template. Check out the guide for the template CLI Introduction.

Example 2. Using User Templates:
$ runai-bgu submit julia \ (1)
  -n conv-2-64 (2)
  --ut train-over-quota-user (3)
  --conda julia_env \ (4)
  -- "julia --project main.jl" (5)
1 Submit a julia workload
2 Specify the job name
3 Use the --ut specify the user template
4 Tells The Job to use the julia_env Conda environment.
5 The command to run, here julia --project.
The space ( ) between the two dashes (--) and the command is intentional. As are the quotes (") surrounding the command.
When running the command you can change directory to the location of your Julia file (cd ~/path/to/file && julia --project main.jl), or give the full path (julia --project ~/path/to/file/main.jl ).
Example 3. Using Group Templates:
$ runai-bgu submit julia \ (1)
  -n conv-2-64 (2)
  --ug train-over-quota-group  (3)
  --conda julia_env \ (4)
  -- "julia --project main.jl" (5)
1 Submit a julia workload
2 Specify the job name
3 Use the --ug specify the group template
4 Tells The Job to use the julia_env Conda environment.
5 The command to run, here julia --project main.jl.
The space ( ) between the two dashes (--) and the command is intentional. As are the quotes (") surrounding the command.
When running the command you can change directory to the location of your Julia file (cd ~/path/to/file && julia --project main.jl), or give the full path (julia --project ~/path/to/file/main.jl ).

Submitting Job

The CLI will display messages about the job creation and status.

Example 4. Synopsis
Start job for training
$ ssh bhn20 (1)
$ runai-bgu submit julia -n conv-2-64 --ut train-over-quota -- "julia --project main.jl" (2)
Waiting for the job to be created...

Job conv-2-64 submitted successfully.
You can check the status of the job by running:
        runai describe job conv-2-64 -p myproj
