Singularity is now Apptainer! What Does This Mean For You? Updates and Enhancements in 2022
An introduction to Apptainer: Apptainer is the most widely used container system for HPC. It is designed to execute applications at bare-metal performance while being secure, portable, and 100% reproducible
As Docker brought containers into enterprise, Singularity brought containers into HPC with a containerization strategy that just works for HPC architectures, security models, and use-cases.
Now Singularity is part of the Linux Foundation and re-released under a new name for the open source project, Apptainer.
While many container systems are built, designed, and optimized for microservices, Apptainer is for applications and computational use-cases.
Portable Jobs and Environments:
Apptainer allows you to bring your environments anywhere creating extreme portability from system to system.
Trusted supply chain / Immutable / Encrypted:
Absolute trust in your environment via cryptographic key validation and encryption.
Singularity, now Apptainer, was created to bring the benefits of container computing to HPC use-cases and system architectures. Within months of release, Singularity was installed on the majority of HPC systems worldwide and facilitated new and innovative non-traditional HPC use-cases.
Singularity is used pervasively throughout HPC centers as well as other community projects and even commercial vendors. The Singularity founder and leading developers are all part of CIQ and we provide enhanced capabilities to customers and partners.
Today, the open source Singularity project has been moved into the Linux Foundation and renamed to Apptainer to better integrate with container innovations and infrastructure capabilities coming out of enterprise, cloud, and hyper scale like OCI and CNCF.
