Slurm PaaS in a cloud environment for development and debug purposes

Nowadays specialized distributed services and sig-nificant amounts of computing resources are used for solving tasks in Big Data processing and analysis. Cloud environments allow people to create virtual clusters with necessary characteris-tics and tune specialized software for planning jobs and resource allocation. Slurm belongs to such systems class. Unfortunately, lots of problems appear during manual setup and Slurm usage in cloud infrastructure. The article offers the solution to the problem of automating deployment of the Slurm cluster in cloud infrastructure for development and testing purposes. User acquires access using REST API request to get ready for use virtual cluster with preinstalled and preconfigured Slurm cluster. This work also includes analysis for Slurm/HPC clusters effi-ciency running in Openstack environment using virtual machines interconnected with an overlay network compared to classical bare-metal HPC clusters.
