A job scheduler determines the job priorities, enforces resource limits and dispatches jobs to available nodes. CPU and memory), schedules jobs and guarantees no interference from other user processes. A resource manager allocates resources (e.g. A workload manager is composed of a resource manager and a job scheduler. An HPC cluster is typically equipped with a workload manager. HPC jobs are often submitted to a batch queue within a workload manager where jobs wait to be scheduled from minutes to days. Nevertheless, typical HPC jobs are large workloads that are normally hardware-specific. Containerising AI applications can be a potential solution.

Furthermore, HPC systems, especially HPC production systems, usually provide a complete stack of software packages which often do not allow user customisation.

In the muti-tenant environment of an HPC cluster, it is difficult to install new software packages since this may alter working environments of existing users and even raise security concerns. HPC is not ready to fully support AI applications due to their complex environment requirements. High Performance Computing (HPC) systems are traditionally applied to perform large-scale financial and engineering simulation that demand low latency and high throughput. īig Data Analytics hosted on Cloud are compute-intensive or data-intensive, mainly due to deployment of Artificial Intelligence (AI) or Machine Learning (ML) applications, which demand extremely fast knowledge extraction in order to make rapid and accurate decisions. The production can benefit from container orchestrators that can provide efficient environment provisioning and auto-scaling. thousands of separate containers may be required in production. Nevertheless, containerised applications can become complex, e.g. Containers are dedicated to run micro-services and one container mostly hosts one application. This feature makes containers more lightweight than VMs. Rather than simulating the holistic operating system (OS) as in a Virtual Machine (VM), containers only share the host OS. Containerisation is a virtualisation technology. Containerisation ensures environment compatibility by encapsulating applications together with their libraries, configuration files and other dependencies, thus enabling users to move and deploy programs easily among clusters.
Cloud computing demands high-portability.
