Abstract

High-level view of the Hobbes Node Virtualization Layer compute node environment. Three enclaves are shown, each running a different application component. The components are composed together across enlaves using shared memory mappings provided by XEMEM [3], copy-on-write memory snapshots provided by XASM [4], I/O mechanisms provided by ADIOS, or by MPI. The Leviathan Node Manager provides a set of tools and infrastructure needed to manage enclaves and application composition.[5]
