Today's "connect anytime and anywhere" society based on the use of digital technologies is fueling tremendous data growth and transforming the way our business, science, and digital technology-based world functions. Data in the terabytes range are not uncommon today and are expected to reach petabytes for many application domains in science, engineering, business, bioinformatics, and medicine in the near future. Ultra-scale refers to the two to three orders of magnitude increase in data sizes, computing power, and complexity of data compared to what is considered today. As data becomes so pervasive, assurance, trust and security of information becomes of paramount importance. Secure computing, therefore, must be considered as an important parameter in any research dealing with ultra-scale computing.
The goal of the Center for Ultra-scale Computing and Information Security (CUCIS) is to conduct highly innovative research in many synergistic areas of ultra-scale computing and information technologies. Furthermore, the goal of the center is to foster and enable inter-disciplinary research in computing technologies that scale to these levels. The CUCIS is directed by Prof. Alok Choudhary, and is presently supported by the NSF, DOE, Sandia National Labs, NASA, and Intel.

Our centers benchmark suite, NU-MineBench, which contains high performance and parallel data mining applications is available for download.

- Exciting News! White House Invitation.
Dr. Choudhary has received an invitation from the White House and will attend the Big Data Event on March 29th. The purpose of the Big Data Event is to address the challenges and opportunities relating to "Big Data". Specifically, the Big Data Event provides the opportunity to learn about several new federal efforts relating to big data and to provide a discussion forum where leaders from government, academia and industry can work together on this important challenge.
- Congratulations to Dr. Choudhary on the recognition of DOE (Department of Energy) supported research through the NSF (National Science Foundation) Expeditions program on climate science problems. The results of this research will be featured in an advertisement by North Carolina State University in the Chronicle of Higher Education and will be published as an article on the DOE (Department of Energy) website.
