Micro-Accelerometer Based Hardware Interfaces for Wearable Computer Mixed Reality Applications
Found in: Wearable Computers, IEEE International Symposium
By A. D. Cheok, K. G. Kumar, S. Prince
Issue Date:October 2002
pp. 0223
Human interaction with wearable computers is an important research issue, especially when combined with mixed reality (MR) applications. Natural and non-obtrusive means of interaction calls for new devices, which should be simple to use. This paper conside...

Aggressively voltage overscaled adaptive RF systems using error control at the bit and symbol levels
Found in: On-Line Testing Symposium, IEEE International
By J. Natarajan, G. Kumar, S. Sen, M.M. Nisar, D. Lee, A. Chatterjee
Issue Date:June 2009
pp. 249-254
Voltage overscaling for power reduction in RF systems has been limited by the need to maintain sufficient overscaling guard bands to ensure that minimum signal quality requirements of the end to end communication link are met. In this paper, we propose err...
Massively parallel landscape-evolution modelling using general purpose graphical processing units
Found in: 2012 19th International Conference on High Performance Computing (HiPC)
By A. S. McGough,S. Liang,M. Rapoportas,R. Grey,G. Kumar Vinod,D. Maddy,A. Trueman,J. Wainwright
Issue Date:December 2012
pp. 1-10
As our expectations of what computer systems can do and our ability to capture data improves, the desire to perform ever more computationally intensive tasks increases. Often these tasks, comprising vast numbers of repeated computations, are highly interde...
Optimus: A Parallel Optimization Framework with Topology Aware PSO and Applications
Found in: 2012 SC Companion: High Performance Computing, Networking, Storage and Analysis (SCC)
By S. Sreepathi,G. Kumar Mahinthakumar
Issue Date:November 2012
pp. 1524-1525
This research presents a parallel metaheuristic optimization framework, Optimus (Optimization Methods for Universal Simulators) for integration of a desired population-based search method with a target scientific application. Optimus includes a parallel mi...

By R. Gandhi, G. Kumar, B. Bederson, B. Shneiderman
Issue Date:September 2000
pp. 591
Users of hypertext systems like the World Wide Web (WWW) often find themselves following hypertext links deeper and deeper, only to find themselves
Poster: a scalable two-phase parallel I/O library with application to a large scale subsurface simulator
Found in: Proceedings of the 2011 companion on High Performance Computing Networking, Storage and Analysis Companion (SC '11 Companion)
By G. Kumar Mahinthakumar, Richard Mills, Glenn Hammond, Sarat Sreepathi, Vamsi Sripathi
Issue Date:November 2011
pp. 67-68
This poster describes the development of a highly scalable application layer parallel I/O library (ASCEM-IO) for scientific applications. This library was envisioned to leverage our earlier I/O optimization experience to build a scalable general purpose pa...
Reduction of communications in a MasPar computer using fuzzy logic concepts
Found in: Proceedings of the 1994 ACM symposium on Applied computing (SAC '94)
By Anand G. Kumar, Joe Hootman
Issue Date:March 1994
pp. 351-356
This paper describes the effects of program restructuring in a dataflow environment. Previous studies showed that dataflow programs can exhibit locality and that a memory hierarchy is feasible in a dataflow environment. This study shows that the order in w...
Deriving good transformations for mapping nested loops on hierarchical parallel machines in polynomial time
Found in: Proceedings of the 6th international conference on Supercomputing (ICS '92)
By A. Basu, D. Kulkarni, K. G. Kumar
Issue Date:July 1992
pp. 82-92
We present a computationally efficient method for deriving the most appropriate transformation and mapping of a nested loop for a given hierarchical parallel machine. This method is in the context of our systematic and general theory of unimodular loop tra...
Loop partitioning for distributed memory multiprocessors as unimodular transformations
Found in: Proceedings of the 5th international conference on Supercomputing (ICS '91)
By A. Basu, A. Paulraj, D. Kulkarni, K. G. Kumar
Issue Date:June 1991
pp. 206-215
The paper traces the development of large multi-transputer systems for high-performance scientific and engineering computing. After defining what we mean by 'supercomputing' in the context of this paper, the past and present state of transputer supercomput...
