The GreenLight project, funded by NSF in July 2008, gets its name from its plan to connect scientists and their labs to more energy-efficient "green" computer processing and storage systems using photonics - light over optical fiber. To achieve this, the project is using a variety of networking resources built upon CENIC's CalREN-XD and CalREN-HPR infrastructure. Project GreenLight is building instrumented modular server facilities (using Sun Modular Data Centers - customized 8'x20' sea storage containers) which utilize optical fiber connections to local and wide area research networks to support a collection of Computer Science and Network Engineering experiments and collaborations, all of which focus on the development of metrics and technologies to help minimize the ICT industry’s environmental impact. Advanced high performance networking technologies (multiple 10GigE DWDM channels providing Layer 2 and 3 connections to multiple experiments - all of which are connected to the CENIC wide area network infrastructure via Cisco and Force10 switches) allow remote access to dozens of GreenLight researchers who test and compare various hardware, system software, and virtualization designs and configurations to determine which optimizations can provide the greatest work/watt. The networking environment also allows these "GreenLight Instruments" to be located near and support larger scale energy generation testing opportunities, such as proximity to existing Photovoltaic resources and a Fuel Cell DC generation system on UCSD's East campus. Experiments involve various hardware architectures and configurations of processors, memory, FPGA and GP GPU coprocessors, bus layouts, communications channels, NICs, power supplies, fans etc. These experiments reside within the GreenLight Instrument and utilize the various environmental sensors to measure the real time  impact on power consumption, thermal dissipation, and related environmental metrics.
