The comput.tional Research and Engineering Acquisition Tools and Environments (CREATE) program is charged with positively impacting the US Department of Defense (DoD) Acquisition Process via comput.tional Engineering for capability gaps identified by the CREATE Boards of Directors. These prioritized requirements have been characterized and are annually reconciled in terms of gaps associated with required analysis cycle-times, physical accuracy, and necessary analysis capabilities. Furthermore, the Office of the Secretary of Defense(OSD) Overarching Integrated Product Team (OIPT) has provided goals which drive the usage of CREATE software by DoD Acquisition programs. In order to achieve these usage targets, the CREATE program has established a governance model and thence a hosted set of services to enhance collaboration among the developer teams and the targeted Acquisition program (AP) subject matter experts. The goals of these collaboration services are to: 1) scale and speed the feedback amongst the CREATE and AP teams, while 2) minimizing interruption to developer and user workflows. Towards these goals, the community services have been architected as discussion forums, issue tracking, and documentation. Such services are now common place in the enterprise and open-source software projects, and efficiently scale with the user community by enabling a searchable knowledge base. In addition, owing to the key capabilities of this DoD software, CREATE requires authenticated and authorized access for each member of the community. This paper summarizes the governance model and process by which the services were selected, the architecture implemented, and the challenges going forward.

Next generation Exascale systems face the difficult challenge of managing the power and thermal constraints that come from packaging more transistors into a smaller space while adding more processors into a single system. To combat this, HPC center operators are looking for methodologies to save operational energy. Energy consumption in an HPC center is governed by the complex interactions between a number of different components. Without a coordinated and system-wide perspective on reducing energy consumption, isolated actions taken on one component with the intent to lower energy consumption can actually have the opposite effect on another component, thereby canceling out the net effect. For example, increasing the setpoint (or ambient temperature) to save cooling energy can lead to increased comput.-node fan power and increased chip leakage power. This paper presents the building blocks required to develop and implement a system-wide framework that can take a coordinated approach to enact thermal and power management decisions at comput.-node (e.g., CPU speed throttling) and infrastructure levels (e.g., selecting optimal setpoint). These building blocks consist of a suite of models that inform the thermal and power footprint of different comput.tions, and present relationships between comput.tional properties and datacenter operating conditions.
