slurm-factory 0.1.33

Slurm builder project by Vantage Compute - builds Slurm packages in Docker containers

Slurm Factory

Build relocatable, GPG-signed Slurm packages using Docker and Spack.

Documentation | Buildcache

Quick Start

Option 1: Install Pre-built Slurm from Buildcache (Fastest!)

Use Spack to install GPG-signed pre-built binaries (no slurm-factory tool needed):

# Install Spack
git clone --depth 1 --branch v1.0.0 https://github.com/spack/spack.git
source spack/share/spack/setup-env.sh

# Add mirrors for dependencies and Slurm
SLURM_VERSION=25.11
TOOLCHAIN=noble  # or: jammy, resolute, rockylinux9, rockylinux10, rockylinux8
CLOUDFRONT_URL=https://slurm-factory-spack-binary-cache.vantagecompute.ai

spack mirror add slurm-factory-deps "${CLOUDFRONT_URL}/${TOOLCHAIN}/slurm/deps/"
spack mirror add slurm-factory-slurm "${CLOUDFRONT_URL}/${TOOLCHAIN}/slurm/${SLURM_VERSION}/"

# Import GPG keys and install Slurm (5-15 min!)
spack buildcache keys --install --trust
spack install slurm@${SLURM_VERSION}

Option 2: Build Custom Slurm with slurm-factory Tool

Install the slurm-factory tool to build custom packages:

# Install Docker and the slurm-factory build tool
pip install slurm-factory

# Build Slurm with default compiler (GCC 13.4.0)
slurm-factory build-slurm --slurm-version 25.11

Operating System Compiler Toolchains

Slurm is built using the default system compiler from each OS distribution:

OS	Codename	GCC Version	GLIBC	Use Case
Ubuntu 24.04	Noble	13.3.0	2.39	Recommended - Modern stable
Ubuntu 26.04	Resolute	15.2.0	2.42	Latest features (development)

Rocky Linux 9	-	11.5.0	2.34	RHEL 9 compatible
Rocky Linux 8	-	8.5.0	2.28	RHEL 8 compatible

GPG Package Signing

All packages are cryptographically signed with GPG for security and integrity.

Why GPG Signing?

• ✅ Authenticity: Verify packages were built by Vantage Compute
• ✅ Integrity: Detect tampering or corruption during download
• ✅ Security: Prevent man-in-the-middle attacks
• ✅ Trust Chain: Establish provenance for production deployments

GPG Key Information

Key ID: DFB92630BCA5AB71
Owner: Vantage Compute Corporation (Slurm Factory Spack Cache Signing Key)
Email: [e-mail]

Importing GPG Keys

Keys are automatically imported when using the buildcache:

# Automatic import and trust
spack buildcache keys --install --trust

# Packages are verified during installation
spack install slurm@25.11%gcc@13.4.0

Features

Download Pre-built Tarball (Alternative)

Download complete Slurm installation as a tarball with GPG signature verification:

# Set versions
SLURM_VERSION=25.11
TOOLCHAIN=noble  # or: jammy, rockylinux9, etc.
CLOUDFRONT_URL=https://slurm-factory-spack-binary-cache.vantagecompute.ai

# Download tarball and signature
wget "${CLOUDFRONT_URL}/builds/${SLURM_VERSION}/${TOOLCHAIN}/slurm-${SLURM_VERSION}-${TOOLCHAIN}-software.tar.gz"
wget "${CLOUDFRONT_URL}/builds/${SLURM_VERSION}/${TOOLCHAIN}/slurm-${SLURM_VERSION}-${TOOLCHAIN}-software.tar.gz.asc"

# Import GPG key
gpg --keyserver keyserver.ubuntu.com --recv-keys DFB92630BCA5AB71

# Verify signature
gpg --verify slurm-${SLURM_VERSION}-${TOOLCHAIN}-software.tar.gz.asc \
             slurm-${SLURM_VERSION}-${TOOLCHAIN}-software.tar.gz

# Extract and install
sudo tar -xzf slurm-${SLURM_VERSION}-${TOOLCHAIN}-software.tar.gz -C /opt/
cd /opt && sudo ./data/slurm_assets/slurm_install.sh --full-init

Package Structure

All builds produce GPG-signed relocatable tarballs:

slurm-25.11-noble-software.tar.gz
├── view/                    # Slurm binaries & libraries
├── modules/slurm/25.11.lua  # Lmod module (relocatable)
└── data/slurm_assets/       # Config templates & install script

Deployment

# Extract (from tarball build)
sudo tar -xzf slurm-25.11-noble-software.tar.gz -C /opt/

# Install (creates users, configs, services)
cd /opt && sudo ./data/slurm_assets/slurm_install.sh --full-init

# Use
module load slurm/25.11

Buildcache Structure

The public buildcache is organized by OS toolchain for optimal performance:

https://slurm-factory-spack-binary-cache.vantagecompute.ai/
├── <toolchain>/
│   └── slurm/
│       ├── deps/            # Slurm dependencies (GPG-signed)
│       ├── 25.11/           # Slurm 25.11 packages (GPG-signed)
│       ├── 24.11/           # Slurm 24.11 packages (GPG-signed)
│       └── 23.11/           # Slurm 23.11 packages (GPG-signed)
├── noble/                   # Ubuntu 24.04
│   └── slurm/
│       ├── deps/
│       ├── 25.11/
│       ├── 24.11/
│       └── 23.11/
├── jammy/                   # Ubuntu 22.04
├── resolute/                # Ubuntu 25.04
├── rockylinux10/            # Rocky Linux 10
├── rockylinux9/             # Rocky Linux 9
├── rockylinux8/             # Rocky Linux 8
└── builds/
    └── <slurm_version>/
        └── <toolchain>/
            ├── slurm-<version>-<toolchain>-software.tar.gz      # Complete tarball
            └── slurm-<version>-<toolchain>-software.tar.gz.asc  # GPG signature

### Mirror Architecture

The buildcache uses a **toolchain-first structure** organized by OS for efficient caching:

1. **`<toolchain>/slurm/deps/`** - Slurm runtime dependencies (OpenMPI, PMIx, Munge, etc.)
2. **`<toolchain>/slurm/<version>/`** - Slurm packages for each version

This separation allows:

- ✅ **Better caching** - Dependencies shared across Slurm versions within a toolchain
- ✅ **OS compatibility** - Packages built with native system compilers
- ✅ **Reduced storage** - No duplication of common packages per toolchain
- ✅ **Parallel downloads** - Spack can fetch from multiple mirrors simultaneously

## Requirements

- Python 3.12+
- Docker 24.0+ (for building from source)
- 50GB disk space
- 4+ CPU cores (8+ recommended)
- 16GB RAM (32GB+ recommended)

For buildcache installs: only Spack required (no Docker needed)
