Installation

pip install -e . # editable install

Usage

# Submit a workflow from YAML file
jrun submit --file workflow.yaml

# Check job statuses
jrun status

# Submit a single job
jrun sbatch --cpus-per-task=4 --mem=16G --wrap="python train.py"

Quick start

Define a tree of jobs

# Define tree
group:
  name: "test"
  type: sequential
  jobs:
    - group:
        type: parallel
        jobs:
          - job:
              preamble: cpu
              command: "echo 'python train.py'"

          - job:
              preamble: cpu
              command: "echo 'python eval.py'"
    - job:
        preamble: cpu
        command: "echo 'python make_report.py'"

# Define preambles
preambles:
  cpu:
    - "#!/bin/bash"
    - "#SBATCH --cpus-per-task=4"
    - "#SBATCH --mem=8G"
    - "#SBATCH --output=slurm/slurm-%j.out"
    - "#SBATCH --error=slurm/slurm-%j.err"

Submit tree and visuzlize

$ jrun submit --file path/to/job/tree.yaml
$ jrun viz # add `--mode mermaid` for mermaid diagram
Job Dependencies:
========================================
6866829 []: (COMPLETED): echo 'python train.py'
6866830 []: (COMPLETED): echo 'python eval.py'
6866831 []: (PENDING): echo 'python make_report.py' <- 6866829, 6866830

Workflow Types

Parameter Sweeps

group:
  name: "sweep-example"
  type: sweep
  preamble: base
  sweep:
    lr: [0.001, 0.01, 0.1]
    model: ["resnet", "vgg"]
  sweep_template: "python train.py --lr {lr} --model {model}"

This creates 6 jobs (3 × 2 combinations) automatically.

Parallel Jobs

group:
  name: "parallel-example"
  type: parallel
  jobs:
    - job:
        preamble: base
        command: "python train_model_a.py"
    - job:
        preamble: base
        command: "python train_model_b.py"

Link jobs with group ids

# Use `{group_id}` in commands to link jobs
group:
  name: "main"
  type: parallel
  jobs:
    - group:
        type: sweep
        preamble: gpu
        sweep:
          lr: [5e-4, 1e-4, 5e-5]
        sweep_template:  "python train.py lr {lr} --group_id {group_id}"  # (e.g., aaa-bbb-ccc)

    - job:
        preamble: cpu
        command: "python eval.py --group_id {group_id}" # (e.g., aaa-bbb)

🌳 JRun Features & Status

Current Features

• Submit job trees from YAML files (jrun submit --file workflow.yaml)
• Monitor job status with visualization (jrun status, jrun viz)
• Parameter sweeps and parallel job execution
• Job graph vizualization
• CLI filtering (jrun status --filter status=COMPLETED)
• Job retry (jrun retry JOB_ID)
• Job delete subgraph
• Web app
• Improve visual for loop group
• Improve dependency (make markovian)
• View job logs in browser
• Delete by node
• Add sweep_idx

Planned Features

• Bugfix: retry not auto updating old job id to new id in deps table
• Update afterany (allow some parent group failures)
• Update node color code (mixed with pending should be blue/active)

Requirements

• Python 3.6+
• SLURM environment
• PyYAML >= 6.0
• tabulate >= 0.9.0
