High Performance Computing is continually growing in scope and areas of research. To cover these new areas of research, HPC has to become more flexible to handle the wide variety of workloads. As the computing becomes more flexible, the infrastructure becomes more complex to accommodate these new varied workloads. At Pittsburgh Supercomputing Center, a Level 1 XSEDE Service Provider, we faced this exact problem for Bridges, our new NSF-funded configurable computing resource. This talk will cover the technical decisions that were made for Bridges, why we made them, the tools we chose, and what the users gain. We chose Openstack Ironic for system installation, Openstack for managing virtual machines, Puppet for configuration, Slurm for scheduling, Naemon, Elastic Search / Logstash / Kibana and InfluxDB for monitoring and reporting. This software gives flexibility to give the users a wide range of ways to do computing at PSC. Additionally, it gives the ability to maintain an even higher level of monitoring and reporting that changes automatically as the systems change functionality.
