What is Singularity
Singularity is a container platform to run complex applications on HPC clusters in a simple, portable, and reproducible way. It supports Docker images and is an alternative to Docker, whose security model and execution mode are not well-suited in an HPC environment.
- Verifiable reproducibility and security, using cryptographic signatures, an immutable container image format, and in-memory decryption.
- Integration over isolation by default. Easily make use of GPUs, high speed networks, parallel filesystems on a cluster or server by default.
- 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.
To setup required environment variables for Singularity, please use following command
|module load singularity/3.8.0
Available singularity images are located under /share1/singularity/simg/ in HPC2021 system.
