Formerly Singularity, the newly named Apptainer project delivers a feature set that supports both application and microservice use cases
The Linux Foundation, the nonprofit organization enabling mass innovation through open source, announced it will host the Apptainer project. Formerly the Singularity project, Apptainer is the most widely used container system for High-Performance (HPC) computing and is one of the container systems uniquely suited for both enterprise and HPC use cases. It is designed to execute applications at bare-metal performance while being secure, portable and completely reproducible.
“The Apptainer project has had massive growth and needs a neutral home with proven open source governance to support its next development and adoption phase,” said Gregory Kurtzer, CEO of CIQ and Founder and Project Lead of Singularity/Apptainer. “The Linux Foundation is the natural host for Apptainer, where it can also collaborate with the Cloud Native Computing Foundation, Open Container Initiative, OpenHPC and other projects to expand its ecosystem.”

The HPC community for many years has been isolated from the enterprise and cloud sectors of the ecosystem, but those barriers are starting to come down. HPC consumers are looking to modernize and take advantage of enterprise tech and enterprises are looking to make use of decades of optimizations in performance and parallelization through use-cases like Artificial Intelligence (AI), Machine Learning (ML) and compute- and data-driven analytics.
“The Apptainer project is at a pivotal moment in its growth and evolution,” said Mike Dolan, senior vice president and general manager of projects at the Linux Foundation. “We look forward to supporting this community and enabling cross collaboration with even more open source developers and technologists to expand its ecosystem of contributors.”
Apptainer features include: public/private key signing of containers; Docker- and OCI-compatible; container encryption and integration with Vault and other management platforms; single-file SIF executable container format; runs “rootless” and prohibits privilege escalation within the container; and supports GPU, FPGA, high-speed networks and filesystems, among others.
