What is Singularity?
Singularity is an open source container platform designed to be simple, fast,
and secure. Many container platforms are available, but Singularity is designed
for ease-of-use on shared systems and in high performance computing (HPC)
environments. It features:
- An immutable single-file container image format, supporting cryptographic
signatures and encryption.
- Integration over isolation by default. Easily make use of GPUs, high speed
networks, parallel filesystems on a cluster or server.
- Mobility of compute. The single file SIF container format is easy to transport
and share.
- A simple, effective security model. You are the same user inside a container
as outside, and cannot gain additional privilege on the host system by
default.
Singularity is open source software, distributed under the BSD License.
