D12.5 - Workload collocation based on container technologies to improve isolation

The aim of this report is to study containers resource isolation and explore Dynamic Resource Assignment techniques to maximize hardware utilization. Containers bring virtualization benefits to High-Performance Computing systems, thus allowing the safe execution of concurrent applications within the same computational node. In this situation it becomes possible to dynamically re-assign resources of multiples applications given their workload, maximizing the useful time the hardware is being used. Nevertheless, containers do not fully isolate their environment from the host, so full isolation is not guaranteed. This report designs, implements and functionally evaluates the workload collocation concept applying dynamic resource assignment solutions for containers.
