The CERCS research center works in three domains: enterprise and datacenter systems; high performance machines and platforms; and embedded/pervasive systems. Within these domains, current core areas of expertise are (1) the multicore stack, including computer architecture, tool chains and compilers, operating systems and hypervisors; (2) energy management, across the entire hardware to datacenter stack and in joint work with other Georgia Tech researchers to address the broader energy ecosystem; (3) systems infrastructure and management, with projects ranging from the development of virtualization and cloud computing technologies to better understanding the services such systems can deliver; and (4) extensive end user engagementand methodology development, in part through CETI@CERCS, our Ohio State center effort.
Lead the innovation of systems, computing, and information technologies, to further the development of the interactive and distributed information services of the future, and to create the intellectual capital that can advance these technologies and fuel future discoveries.
The Georgia Tech CERCS project 'CoolIT', developed in collaboration with the Mechanical Engineering department, allows the synergistic and cooperative management of IT and cooling system resources, adjusting air velocity and the location of active computing simultaneously to minimize power consumption. Initial results attained in CoolIT highlight the interesting tradeoffs faced by a coordinated management solution. For instance, at lower cooling air velocities, for a homogeneous set of server systems, an awareness of hot spots in the data center permits the IT management system to operate at close to 100% maximum performance load, whereas without such awareness, there are situations in which only 40% load is achieved. These results illustrate the significant benefits of coordination between computer and facilities power management.
