First Experience and Practice of Cloud Bursting Extension to OCTOPUS

In the Cybermedia Center at Osaka University, OCTOPUS (Osaka university Cybermedia cenTer OverPetascale Universal Supercomputer) has provided for providing a high performance computing environment for scientists and researchers in Japan since April 2017. OCTOPUS enables a stable operation with only a few technical problems. However, due to higher and higher computing demands, the users’ waiting time from job submission to job completion has been increasing. In this research, we explore the feasibility of solving this problem by offloading the computational workload to IaaS Cloud services, in the hope that we can alleviate the high utilization on OCTOPUS. Technically, we build a cloud bursting environment where OCTOPUS as an on-premise computing environment and Microsoft Azure as an IaaS Cloud service are integrated. Therefore, we investigate whether the cloud bursting environment is useful and practical for avoiding high utilization on OCTOPUS. In this paper, we summarize the first experience and practice of our cloud-bursting solution.
