Awasthi, Manu; Nellans, David W.; Sudan, Kshitij; Balasubramonian, Rajeev | ABP : predictor based management of DRAM row buffers | DRAM accesses are costly, especially in multicore systems. Future CMPs will run a mixed load of workloads/threads. Destructive interference at memory controller, spatio-temporal locality lost! DRAM row-buffer hits are least expensive, row-conflicts are most. Randomized memory access patterns re... | 2010-10-06 | |

Pascucci, Valerio | Efficient data restructuring and aggregation for I/O acceleration in PIDX | Hierarchical, multiresolution data representations enable interactive analysis and visualization of large-scale simulations. One promising application of these techniques is to store high performance computing simulation output in a hierarchical Z (HZ) ordering that translates data from a Cartesian ... | 2012-01-01 | |

Kasera, Sneha K. | Enhancing covert communications with multiple colluding receivers | Traditional (single receiver) system setup: ? Choose exploit field (e.g. last byte of TCP Timestamp) ? Alice: probabilistically inject parts of coded message into field ? Bob: extract symbols from field, decode to correct errors ?Warden: assume full knowledge of system and keys Can we create un... | 2010-10-06 | |

Grosset, Andre Vincent Pascal; Pascucci, Valerio | Infinite Zoom | Any image (apart from a fractal) has a finite resolution. On zooming in, we eventually see pixels. The aim of this project is to allow users to infinitely zoom in on an image. | 2010-10-06 | |

Li, Guodong; Gopalakrishnan, Ganesh; Kirby, Robert Michael Ii | PUG : A Symbolic Verifier of GPU Programs | PUG is a automated verifier for GPU programs written in C/CUDA. PUG verifies GPU kernels for Data Races, Barrier mismatches, Totally wrong results, and Weak memory model related bugs. SMT-based correctness checking methods for these error are often more scalable, general and modular. | 2010-10-06 | |

Potter, Kristin Carrie | Uncertainty visualization in forward and inverse cardiac models | Quantification and visualization of uncertainty in cardiac forward and inverse problems with complex geometries is subject to various challenges. Specific to visualization is the observation that occlusion and clutter obscure important regions of interest, making visual assessment difficult. In orde... | 2013-01-01 |
