Before diving into Singularity containers, it’s useful to understand the concept of containers in general and a bit of their history.
Researchers at Lawrence Berkeley National Laboratory created Singularity containers as an open-source project in 2015. Their goal was to bring containers and reproducibility to scientific computing and the high-performance computing (HPC) world, addressing the challenges of sharing and running scientific workloads across different computing environments and multi-tenant systems. Singularity containers are similar to Docker containers but have some key differences that make them better suited for scientific research.
One of the key differences between Singularity and Docker is that Singularity containers are designed to run as a non-privileged user. This is important for security reasons, as running containers as root can potentially give attackers access to the host system. Singularity offers several benefits over Docker:
The Singularity Image Format (SIF) is a container image format that is specifically designed for Singularity containers. It allows users to easily share Singularity container files and distribute them across different computing environments. In essence, SIF is a single file and specification that supports the bundling of metadata and enables image signing and verification, and image encryption. Sylabs is also planning to introduce support for the encapsulation of OCI data and configurations in SIF.
Users rely on Singularity for a wide range of use cases, including the following.
Singularity is used extensively in HPC environments to provide a consistent and portable software environment across different clusters and architectures. Singularity containers natively support resource managers, InfiniBand, MPI, GPUs, parallel file systems, and more on HPC clusters, ensuring that the application and its dependencies are properly configured.
AI practitioners use Singularity for a variety of use cases, including computer vision, natural language processing, and machine learning. By providing a way to package GPU-enabled AI models and dependencies, Singularity makes it easy to deploy them on different platforms and architectures. This can help simplify the process of deploying models in production.
Singularity containers are used in bioinformatics to facilitate collaboration and reproducibility of analyses, as well as to overcome challenges such as dependency management, software installation, and cross-platform compatibility. For example, users can rely on Singularity containers to run bioinformatics tools such as BLAST, Bowtie2, BWA, GATK, etc. on different platforms while reducing issues associated with complex overlapping dependencies.
Researchers rely on quantum circuit simulation to create simulators that mimic the quantum phenomena of superposition and entanglement. These simulators help researchers from various domains and sectors develop and test algorithms for quantum computers. Researchers use the reproducibility, portability, and isolation features in Singularity containers to accelerate quantum simulation and workloads.
Singularity containers can help decouple EDA toolchains from operating systems. EDA tools often require specific operating system versions and libraries, which can limit their compatibility and usability across different platforms. Singularity can encapsulate these tools and their dependencies in a portable virtual environment that can run on any Linux system.
Singularity and the SIF file format offer a powerful opportunity to streamline your workflows, increase productivity, and collaborate more effectively with other teams while providing verifiable reproducibility and security. Whether you’re just getting started with containers or looking for a more advanced tool to help you take your work to the next level, Singularity is worth exploring. At Sylabs, we offer multiple versions of Singularity, including SingularityCE, SingularityPRO, and Singularity Enterprise, that are designed to support the gamut of organizational sizes and needs.
