Sarus - An OCI-compatible container engine for HPC

release: 1.6.4

Sarus is a software to run Linux containers on High Performance Computing environments. Its development has been driven by the specific requirements of HPC systems, while leveraging open standards and technologies to encourage vendor and community involvement.

Key features:

  • Spawning of isolated software environments (containers), built by users to fit the deployment of a specific application

  • Security oriented to HPC systems

  • Extensible runtime by means of OCI hooks to allow current and future support of custom hardware while achieving native performance

  • Creation of container filesystems tailored for diskless nodes and parallel filesystems

  • Compatibility with the presence of a workload manager

  • Compatibility with the Open Container Initiative (OCI) standards:

    • Can pull images from registries adopting the OCI Distribution Specification or the Docker Registry HTTP API V2 protocol

    • Can import and convert images adopting the OCI Image Format

    • Sets up a container bundle complying to the OCI Runtime Specification

    • Uses an OCI-compliant runtime to spawn the container process
