Moby Dock in the Wind Tunnel
summary
Demonstrates Docker/Moby as a lightweight alternative to full VMs for HPC, presenting benchmarks (including an IBM Docker paper and an internal Abaqus microbenchmark on CentOS) that show roughly 2% overhead versus bare metal across setups with InfiniBand, Lustre and local RAID. Describes use cases like packaging multiple application versions, creating portable workflows, and deploying apps to heterogeneous clusters, while noting caveats around kernel-shared isolation (LXC), multi-tenant security risks, and the need for wrapper/startup policies and signed local image registries.
