Index Key Features MPI Ready : Full OpenMPI support with intra-node and inter-node job execution : Full OpenMPI support with intra-node and inter-node job execution User Management : User synchronization from head node to workers via mounted home volume : User synchronization from head node to workers via mounted home volume Shared Configuration : All SLURM configs shared via mounted volume : All SLURM configs shared via mounted volume Full Job Accounting (Optional) : Complete sacct functionality with MariaDB backend. You can opt not to start the database container and the system will still work, just without accounting : Complete functionality with MariaDB backend. You can opt not to start the database container and the system will still work, just without accounting Runtime customisation: Install additional software onto the cluster at container startup without the need to rebuild the image, see Install Extra Packages below Usage Quick start Simply docker compose up -d The virtual cluster will start up in its default configuration: One login node Two worker nodes with 4 vCPU each and 2048M of vRAM with 4 vCPU each and 2048M of vRAM Full accounting via a database node (MariaDB) Accessing the Cluster Although it is of course ...
