Computer Architecture and Systems Laboratory (CASL) is part of the NSF Industry University Cooperative Research Center on Experimental Research in Computer Systems (www.cercs.gatech.edu). Our efforts are focused primarily on the exploration of novel concepts in computer architecture with a current emphasis on heterogeneous computing, power and thermal issues, and interconnection networks and memory hierarchies. The efforts are guided by an experimental philosophy that develops hardware and software artifacts and consequently are influenced by emerging standards. Towards this end, and through Georgia Tech, we are members of the Hypertransport Consortiumand have been past members of the Open Core Protocol Consortium.
Our current projects are broadly guided by the following themes. The first is the need for new scalable modeling and simulation infrastructures to support research efforts in many core architectures, which we are applying to the study of the integration of interconnection networks and memory systems. The second is heterogeneous computing with a focus on GPU accelerators and supporting execution environments. The third is on understanding the impact of the physics of operation (e.g., thermal, device degradation, etc.) on system performance and driving architecture operation and design.
We gratefully acknowledge the support of these efforts by the National Science Foundation, Sandia National Laboratories, Los Alamos National Laboratories, Samsung, LogicBlox, AMD, Intel, IBM, SRC, and NVIDIA, as well as the support of past projects by HP Labs, DARPA, and ONR.
