hpc-runner 0.2.0

Unified HPC job submission across multiple schedulers

hpc-runner

Unified HPC job submission across multiple schedulers

Write your jobs once, run them on any cluster - SGE, Slurm, PBS, or locally for testing.

Features

• Unified CLI - Same commands work across SGE, Slurm, PBS
• Python API - Programmatic job submission with dependencies and pipelines
• Auto-detection - Automatically finds your cluster's scheduler
• Interactive TUI - Monitor jobs with a terminal dashboard
• Job Dependencies - Chain jobs with afterok, afterany, afternotok
• Array Jobs - Batch processing with throttling support
• Virtual Environment Handling - Automatic venv activation on compute nodes
• Module Integration - Load environment modules in job scripts
• Dry-run Mode - Preview generated scripts before submission

Installation

pip install hpc-runner

Or with uv:

uv pip install hpc-runner

Quick Start

CLI

# Basic job submission
hpc run python train.py

# With resources
hpc run --cpu 4 --mem 16G --time 4:00:00 "python train.py"

# GPU job
hpc run --queue gpu --cpu 4 --mem 32G "python train.py --epochs 100"

# Preview without submitting
hpc run --dry-run --cpu 8 "make -j8"

# Interactive session
hpc run --interactive bash

# Array job
hpc run --array 1-100 "python process.py --task-id \$SGE_TASK_ID"

# Wait for completion
hpc run --wait python long_job.py

Python API

from hpc_runner import Job

# Create and submit a job
job = Job(
    command="python train.py",
    cpu=4,
    mem="16G",
    time="4:00:00",
    queue="gpu",
)
result = job.submit()

# Wait for completion
status = result.wait()
print(f"Exit code: {result.returncode}")

# Read output
print(result.read_stdout())

Job Dependencies

from hpc_runner import Job

# First job
preprocess = Job(command="python preprocess.py", cpu=8, mem="32G")
result1 = preprocess.submit()

# Second job runs after first succeeds
train = Job(command="python train.py", cpu=4, mem="48G", queue="gpu")
train.after(result1, type="afterok")
result2 = train.submit()

Pipelines

from hpc_runner import Pipeline

with Pipeline("ml_workflow") as p:
    p.add("python preprocess.py", name="preprocess", cpu=8)
    p.add("python train.py", name="train", depends_on=["preprocess"], queue="gpu")
    p.add("python evaluate.py", name="evaluate", depends_on=["train"])

results = p.submit()
p.wait()

Scheduler Support

Scheduler	Status	Notes
SGE	Fully implemented	qsub, qstat, qdel, qrsh
Local	Fully implemented	Run as subprocess (for testing)
Slurm	Planned	sbatch, squeue, scancel
PBS	Planned	qsub, qstat, qdel

Auto-detection Priority

1. HPC_SCHEDULER environment variable
2. SGE (SGE_ROOT or qstat available)
3. Slurm (sbatch available)
4. PBS (qsub with PBS)
5. Local fallback

Configuration

hpc-runner uses TOML configuration files. Location priority:

1. --config /path/to/config.toml
2. ./hpc-tools.toml
3. ./pyproject.toml under [tool.hpc-tools]
4. Git repository root hpc-tools.toml
5. ~/.config/hpc-tools/config.toml
6. Package defaults

Example Configuration

[defaults]
cpu = 1
mem = "4G"
time = "1:00:00"
inherit_env = true

[schedulers.sge]
parallel_environment = "smp"
memory_resource = "mem_free"
purge_modules = true

[types.gpu]
queue = "gpu"
resources = [{name = "gpu", value = 1}]

[types.interactive]
queue = "interactive"
time = "8:00:00"

Use named job types:

hpc run --job-type gpu "python train.py"

TUI Monitor

Launch the interactive job monitor:

hpc monitor

Key bindings:

• q - Quit
• r - Refresh
• u - Toggle user filter (my jobs / all)
• / - Search
• Enter - View job details
• Tab - Switch tabs
