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.

- 12/18/2013 Postdoctoral researcher positions available now -- we are looking for postdoctoral associates to conduct research in the areas of data ming, database management, and high-performance computing. See the Job Posting for contact information.
Software Developed by the Center:
- NU-MineBench -- a collection of data mining algorithms and applications in sequential and parallel
- Parallel netCDF -- a parallel I/O library for accessing netCDF files
- AGILE -- a sequence mapping tool to map the long reads to a given reference genome
- Pairwise Statistical Significance -- a sotfware suite that estimates the statistical significance of local sequence alignment (in MPI, OpenMP, and CUDA)
- Fast Max Clique Finder -- a sotfware suite to find the maximum cliques of large sparse graphs
- Prof. Alok Choudhary has received major funding for his big data startup, 4C. The amount of $5 million from Chicago-based venture fund Jump Capital was awarded to the Social Intelligence Company based on 4C's platforms application of algorithms. Based on decades of research by Prof. Choudhary, these algorithm mine social-media data around the globe to help advertisers target their campaigns on television, Twitter, Facebook and other media channels.
