  • 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:
