Supporting storage resources in Urgent Computing Environments

The special priority and urgent computing environment (SPRUCE) provides on-demand access to high-performance computing resources for time-critical applications. While SPRUCE supports computationally intensive applications, it does not fully support high-priority, data intensive applications. To support data intensive applications in urgent computing environments, we developed the urgent computing environment data resource manager (CEDAR). CEDAR provides storage resource provisioning capabilities that manage the availability and quality of service of storage resources used by urgent computing applications. In this paper, we describe the architecture of CEDAR, illustrate how CEDAR will integrate with urgent computing environments, and evaluate the capabilities of CEDAR in simulated urgent computing environments.
