Sessions
Research computing organizations facilitate scientific investigations by providing access to computational resources, advanced networking, and ample storage to support the demands of scientific workflows. Traditional HPC systems run as self-contained environments with a head node that defines access to all resources and orchestrates operation of the cluster. Managing access to these services over the various lifetimes of hardware, software, clusters, and facilities presents challenges in maintaining access for users to different systems as they evolve. At UAB we are building a software defined HPC environment to manage evolution of our systems by implementing an A/B testing framework that leverages Open OnDemand as the web interface to different generations of hardware.
