Description
This contribution reports on solutions, experiences and recent developments with the dynamic, on-demand provisioning of remote computing resources for analysis and simulation workflows. Local resources of a physics institute are extended by private and commercial cloud sites, ranging from the inclusion of desktop clusters over institute clusters to HPC centers.
We report on recent experience from incorporating a remote HPC center (NEMO Cluster, Freiburg University) and resources dynamically requested from a commercial provider (1&1 Internet SE), which have been seamlessly tied together with the ROCED scheduler [1] such that, from the user perspective, local and remote resources form a uniform, virtual computing cluster with a single point-of-entry. On a local test system, the usage of Docker containers has been explored and shown to be a viable and light-weight alternative to full virtualization solutions in trusted environments.
