singularity
An open source container platform designed for simplicity, speed, and security in HPC and shared computing environments.
What is singularity?
Singularity is an open source container platform specifically designed for high performance computing (HPC) and shared computing environments. It solves the problem of running containers securely in multi-user systems where traditional container platforms face security and usability challenges. The platform emphasizes simplicity, speed, and security with its unique single-file container format.
Researchers, scientists, and system administrators working in HPC clusters, academic institutions, and shared computing environments who need to run containerized applications with access to specialized hardware.
Developers choose Singularity over other container platforms because it provides a secure, user-friendly way to run containers in shared environments without requiring root privileges. Its integration-focused design makes it easier to leverage GPUs, high-speed networks, and parallel filesystems compared to isolation-heavy alternatives.
Overview
Singularity has been renamed to Apptainer as part of us moving the project to the Linux Foundation. This repo has been persisted as a snapshot right before the changes.
